Carcharodontosaurus – An Enormous Carnivorous Dinosaur

Paleo Paul has been busy with his camera again as this week, team members at Everything Dinosaur were emailed some photographs of the latest addition to his fossil collection, a magnificent broken tooth from a very large theropod dinosaur. In his email, Paleo Paul explained that the tooth was from a North African, meat-eating dinosaur called Carcharodontosaurus, a dinosaur whose fossils first came to the attention of the scientific community in the early part of the 20th century, although Carcharodontosaurus was not named and formally described until 1931.

The Large Theropod Tooth (Carcharodontosaurus)

Carcharodontosaurus saharicus

Paleo Paul wrote to say that this dinosaur was named and described by the famous German palaeontologist Ernst Stromer von Reichenbach and this is a beautiful specimen. In many of the fossil carcharodontid teeth that we have examined, the tip of the tooth is often missing and Paleo Paul is lucky to have this specimen in his fossil collection. This is a broken tooth, the root is missing, this tooth was most probably shed when this dinosaur was alive.

The tooth may have been lost when this carnivore was either feeding or fighting. Scientists now know that North Africa around 98 million years ago (Late Albian to Early Cenomanian faunal stages) was home to a number of large predatory dinosaurs. Carcharodontosaurus saharicus is regarded as an apex predator, some of the teeth associated with this species are nearly twenty centimetres long!

The photograph above shows a close up the tooth serrations (denticles) which are found on the carinae (sharp edges) of the tooth. The shape, number and size of these denticles are helpful when attempting to identify which dinosaur the tooth likely came from.

Denticles can be found on both the leading edge (anterior) and the rear edge of the tooth (posterior), most theropod teeth have two carinae therefore, in bilateral symmetry, but not always, the carinae can be offset or even split in some genera. Being able to see clearly defined denticles such as these reflects the high degree of preservation of this particular fossil tooth. Well done to Paleo Paul for getting a super close up photograph!

An Apex Predator

Carcharodontosaurus saharicus was very probably the top predator in its environment. In the Everything Dinosaur database, we record C. saharicus as being potentially, up to fourteen metres long, reaching a head height of nearly six metres and weighing in excess of 6,000 kilogrammes. It really was a formidable animal. Carcharodontosaurus is very popular amongst dinosaur fans and Paleo Paul also sent in a couple of pictures of his CollectA Deluxe Carcharodontosaurus model

Titanosaurs Crossing Continents – Savannasaurus elliottorum a New Dinosaur is Named

By Mike|2024-05-06T15:28:26+01:00October 21st, 2016|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Photos/Pictures of Fossils|0 Comments

“Wade” Finally Gets a Name – Savannasaurus elliottorum

An Australian titanosaur, nicknamed “Wade”, whose fossilised bones were discovered in 2005, has been formally described and named. Say hello to Savannasaurus elliottorum, the scientific name may not be as catchy as its nickname, but this specimen does represent one of the most complete titanosaurs discovered in Australia to date and its discovery is helping palaeontologists to piece together how these giant, herbivorous dinosaurs crossed continents, spreading out from South America and reaching Australia via Antarctica.

An Australian Giant – Savannasaurus elliottorum

David Elliot, one of the co-founders of the Australian Age of Dinosaurs Museum, the museum established close to the town of Winton in Queensland that exhibits many of the Cretaceous fossils found in this region, spotted some fossil bones sticking out of the ground early in 2005. Mr Elliott returned to the site later in the day with his wife Judy to take a closer look at the fossil fragments. He hoped that the bones might represent a theropod, but this idea was quickly put to one side when his wife “clicked” two bones together to make a distinctive metatarsal (toe bone) of a sauropod.

The site was excavated in September 2005 by a joint Australian Age of Dinosaurs Museum and Queensland Museum team and seventeen pallets of bones encased in rock were recovered.

It has taken more than ten years or preparation work for the fossilised bones to be removed from the single silt stone concretion that encased them. Everything Dinosaur has regularly reported on Australian dinosaur fossil discoveries and kept tabs on the progress of the “Wade” preparation work.

To read an earlier article (2013), on the preparation work: An Update on Wade the Aussie Dinosaur.

Why “Wade”?

The nickname for this new species of titanosaur honours Australian palaeontologist Dr Mary J. Wade. During her long career, Dr Wade did much to help conserve and promote the extensive, exposed fossil bearing strata of Queensland. She worked on a number of iconic Australian dinosaurs including Muttaburrasaurus as well as helping to map and study Precambrian fossils that were later to be described as Ediacaran biota.

Although one of the more complete Australian titanosaur fossils yet described, the material is highly fragmentary and only about five percent of the skeleton has been recovered. The fossils consist of one neck vertebra, several cervical ribs, eight dorsal vertebrae making up a partial sequence, several rib fragments, sacral vertebrae and at least five fragmentary tail bones (caudal vertebrae). Limb bones are represented, several toe bones, elements from the ankle, bones from the manus (front feet) as well as incomplete humeri (upper arm bones).

The research team and volunteers were also able to recover a partial left radius and a highly fragmentary ulna and parts of the hip girdle. Although no cranial (skull) material was recovered, the team were confident, almost from the start, that these bones represented a new species. The fossils come from a site called “Belmont Station”, ironically, nearby cranial material from another, previously described titanosaur was found (Diamantinasaurus matildae). In the scientific paper which describes Savannasaurus, published in the journal “Nature”, the authors, which include lead researcher Dr Stephen Poropot, (Australian Age of Dinosaurs Museum), describe the braincase and neck bones of Diamantinasaurus.

Plotting the Distribution of the Titanosauria

These two titanosaurs are being used to help map the dispersal of the Titanosauria across the super-continent Gondwana as this huge landmass began to break up. Although the fossil record remains patchy to say the least, the fossils, which have been dated to around 98-95 million years ago (Cenomanian faunal stage of the Late Cretaceous), suggest that by this time in Earth’s history titanosaurs had dispersed from South America, migrated across Antarctica and entered the landmass that was later to become Australia.

Commenting on the significance of these fossils, Dr Stephen Poropot stated:

“We get a much better idea of the overall fauna. And as a result, we can start piecing together how climate affected these dinosaurs, how the positions of the continent affected those dinosaurs and how they evolved through time as well.”

Dispersal of the Titanosauria

Although, palaeontologists have discussed a number of potential dispersal routes, it is likely that these types of dinosaurs had entered Australia from South America, presumably crossing Antarctica. During the late Early Cretaceous the Earth went through a period of global warming. Prior to this climate change, titanosaurs, which were globally widespread in the Early Cretaceous were prevented from reaching Australia by the cold conditions in Antarctica. Global warming facilitated the dispersal of sauropods from South America to Australia via Antarctica.

Etymology of Savannasaurus elliottorum

The genus name is derived from the Spanish (Taino) “zavana”(savanna), a reference to the grassland and pasture in which the specimen was found. The species name honours the Elliott family for their continuing contributions to Australian palaeontology.

Differences between Savannasaurus and Diamantinasaurus

Although Savannasaurus and Diamantinasaurus were contemporaneous of each other and these giant herbivores may have been roughly the same size, living in the same habitat, preliminary measurements indicate that the forelimbs of Savannasaurus are proportionally quite different from those of Diamantinasaurus. This may suggest adaptation to a different feeding platform, allowing these large dinosaurs to co-exist without competing with each other for food.

A Review of Prehistoric Times Magazine (Autumn 2016)

The bumper autumn edition of Prehistoric Times has hit the office mat and Everything Dinosaur team members have been eagerly thumbing through its colourful pages. All hail talented palaeoartist Fabio Pastori whose depiction of the tyrannosaurid affectionately known as Stan (STAN-BHI3033) adorns the front cover. This is the fifth time that Fabio has produced front cover artwork for Prehistoric Times, it is always a pleasure to see his work and sure enough, there is plenty of Fabio’s amazing prehistoric themed artwork to marvel at inside, look out for the “picture perfect Cryolophosaurus” article.

Acrocanthosaurus and Eohippus Inside

The two featured prehistoric animals in this issue are the monstrous Acrocanthosaurus and the diminutive “dawn horse” Eohippus, Phil Hore does a good job producing updates on these two ancient creatures and both his articles are embellished with plenty of reader submitted artwork.

Amongst our favourites in the Acrocanthosaurus dedicated copy is the line drawing by Rich Morris and the image created by Manuel Gil Jaramallo, which reminded us of the Battat Acrocanthosaurus replica.

Look out for the wonderful model of Eohippus made by the great and sadly no longer with us, Ray Harryhausen, for the 1969 fantasy adventure film “Valley of the Gwangi”.

Regular contributor Tracy Lee Ford dedicates his how to draw dinosaurs series to Torosaurus and unravelling the rather complicated relationship this large herbivore has with other Late Cretaceous members of the Chasmosaurinae clade. Once again this is a very well written and informative piece.

Fabio Pastori

Fabio Pastori’s artwork can be seen throughout much of this edition of Prehistoric Times. For example, in an article on spectacular Upper Jurassic fossils “What is Quarry 5?” Fabio’s illustrations are used to bring various stegosaurs and sauropods to life.

Hiding in Plain Sight the “Higgs Bison”

By Mike|2023-05-08T10:48:38+01:00October 19th, 2016|Animal News Stories, Dinosaur and Prehistoric Animal News Stories, Main Page|0 Comments

Cave Paintings Reveal Surprising Clues to Bovid Evolution

The cave paintings left by our ancestors can be very evocative. The often elaborate and highly stylised frescoes represent life in the very distant past, a life so far removed from today. However, the paintings, in most cases, a record of the animals that shared the environment with these hunter/gatherers, hide hidden clues regarding prehistoric animals that modern-day researchers are only just beginning to appreciate. Cave art has helped to confirm the exisitence of a newly described bison species, nicknamed the “Higgs Bison”.

Climate Change Affecting Large Animal Populations

A report published in the journal “Nature Communications” by scientists from the University of Adelaide, documents the study of DNA recovered from fossil bones in order to map how climate change affects large animals. A surprise awaited the scientists, they have discovered a previously unknown species of bison, only to find out that this bovine was already recorded on the walls of caves across Europe, such as in the Niaux Cave (south-western France). These cave paintings are dated to around 17,000 years ago (Late Upper Palaeolithic).

In 1999, the Australian-based research team commenced the study of DNA extracted from bison bones excavated from a number of sites located in the Northern Hemisphere, where the Steppe bison (Bison priscus) roamed. The objective of the study was to assess the impact of changing global climate upon animal populations and in North America the fossil record for bison reflected the impact of a changing world. Bison numbers crashed around the Last Glacial Maximum (between 18,000 and 21,000 years ago.)

Megafauna Extinction

Such data supports the idea that climate change played a significant role in the extinction of “megafauna”.

The scientists then expanded the boundaries of their research by examining data from South America, this also revealed that rapid warming events were a significant factor in large animal extinctions, often with species being further pushed towards extinction by the effect on animal populations by human hunters.

A Puzzle from Europe

When the focus of the research was directed at the fossil record and climate data from Europe, a rather puzzling picture emerged. By studying mitochondrial DNA (which is inherited exclusively through the maternal line), recovered from fossilised remains, the team realised that the genetic signatures they were finding did not match those expected if the fossils had come from the Steppe bison (Bison priscus). This was something of a puzzle as palaeontologists had thought that the Steppe bison was the only species to have been present in Europe before 10,000 years ago.

The European Bison (Bison bonasus)

The researchers realised that there were looking at the genes of something novel, an unknown species distantly related to modern cattle and to the exceptionally rare European bison (Bison bonasus), also called the Wisent. The European bison is Europe’s largest, native, extant terrestrial mammal. Once widespread, this bovine is now found in a few, remote and protected forests, particularly the Białowieża Forest between Belarus and Poland.

In a story, somewhat similar to the more famous Przewalski’s horse, the last wild Wisent was shot in 1927, but the species clung on thanks to a handful of animals kept in protected reserves. Modern herds are descended from just a dozen individuals, including one bull from the Caucasus.

The Elusive “Higgs Bison”

That famous Australian dry sense of humour came to the fore, when the DNA from the fossil bones proved to be neither Steppe bison or modern European bison, the team thought they had a new species but they could not be certain. The elusive animal was nick-named “Higgs bison”, after all, the team had found evidence of something new, but they were not quite sure what this animal looked like, a parallel with physicists and their search for the Higgs boson particle.

In order to unravel this “Higgs bison” puzzle, the University of Adelaide research team set out to confirm their mitochondrial DNA results by obtaining nuclear DNA from the sixty-four European bison bones involved in the study. Although, much harder to retrieve, nuclear DNA records all aspects of ancestry, not just the maternal line. The small amount of nuclear DNA retrieved from the samples demonstrated that the “Higgs bison” was a hybrid, a cross between a female wild cow (extinct Aurochs) and a male Steppe bison.

The “Higgs Bison” and Hybridisation

The team dated this hybridisation event to more than 120,000 years ago. This ancestry was the same for the Wisent and even though the mitochondrial DNA was different, a consequence of the recent near extinction event for the European bison, the “Higgs bison” was revealed as the ancestor of the Wisent.

Pressure on bovine populations as a result of rapid fluctuations in climate could have triggered the hybridisation process.

Male offspring of the Aurochs/Steppe bison cross were sterile, a common outcome for mammal hybrids. As a result, several generations of females back-crossed with Steppe bison males (maybe even the same bull), resulting in a genetic ancestry of about 10 percent Aurochs and 90 percent Steppe bison.

Hybridisation Between Female Aurochs and Male Steppe Bison Leads to a New Species

Genetics and cave art reveal the assymmetric hybridisation between female Aurochs and male Steppe bison. Male hybrid offspring are sterile, and female offspring backbred with Steppe bison for several generations, possibly the same bull.

Looking for More Evidence – the North Sea and Cave Paintings

Having reached this conclusion, the Australian team then set about finding other sources of evidence to support the idea of a newly discovered species of prehistoric bison, resulting from the cross breeding between wild cattle and Bison priscus. Two strands of supporting evidence were identified, both from surprising sources.

Scientists from Holland reported that amongst the many numerous Steppe bison and Aurochs bones dredged up by fisherman from the North Sea (for much of the Pleistocene Epoch sea levels were much lower and Scotland was joined to Denmark by a wide and extensive plain), bones of a less common, smaller bovine had been found.
French cave art researchers had identified two distinct forms of bison depicted in the artwork of our ancestors, one type resembled the hump-backed, massive Steppe bison, whilst the other depiction was of a more evenly shaped animal with reduced horns, much like a modern-day Wisent.

Depicted in Prehistoric Cave Art – the Newly Discovered Species of Bison

A Wisent (European bison) depicted in Cave Art

820 examples of bison depicted in European cave art are known, two distinct forms have been identified, representing two different species.

Picture: D. Viat/Tourismeoccitanie

Radiocarbon Dating of Cave Art

Radiocarbon dating of the artworks showed that the wedge-shaped form was drawn when Steppe bison were present on the landscape (around 18,000 years ago), while the small-horned version was drawn when the newly discovered species dominated Europe (after 17,000 years ago). Each species appears to have dominated Europe for long periods of time, alternating in response to major climate changes.

Thanks to the accurate artwork of Stone Age people, scientists have a good understanding of what this new species of bison looked like. It had been hiding in plain sight all along.

This study has thrown up a number of surprises. Apparently, mammals can form new species by hybridisation, even if only rarely. It also shows that despite the huge bison fossil record the depictions of these ancient creatures made many thousands of years ago, still have a lot to tell us about life in the past.

Safari Ltd Prehistoric Animal Retirements 2017 Some Important News

By Mike|2024-05-06T15:29:44+01:00October 18th, 2016|Dinosaur Fans, Main Page, Press Releases|0 Comments

Prehistoric Animal Models Being Retired by Safari Ltd in 2017

Much has been said about Safari Ltd’s drip feeding of information with regards to their new models and replicas. Everything Dinosaur team members have tended to stay on the fence as it were, but we do know that there has not been much said about which models are being retired and coming out of production. In this brief blog post we intend to address this.

For model collectors and dinosaur fans knowing what new replicas are coming is great, but it is also extremely important to know which models are not going to be made any more.

Lots of Fuss About the New Models but Which Ones are Going?

Some of the new for 2017 prehistoric animal models.

A montage of new model images from Safari Ltd.

Time to flip the coin and give our ten cents worth on the prehistoric animal retirements from Safari Ltd.

Gastornis is Gone!

Fans of this particular “Terror Bird” are going to miss this replica of the giant, flightless Gastornis or should that be Diatryma? There is still some debate as to just how distinct these two genera are. However, after a little more than three years, this colourful and highly collectable replica is going to go to that great big aviary in the sky. Models of “Terror Birds” are rare and with the demise of this particular figure, they are likely to become rarer still. If you have not got this replica yet, snap it up quick – or should that be “quack” after all, as a member of the Anseriformes, Gastornis is distantly related to today’s ducks.

Tree Fern Felled!

Also for the chop is the tree fern model, one of three prehistoric plants (cycad and agathis conifer being the other two), in the Wild Safari Prehistoric World range. These replicas proved to be very popular with dinosaur diorama makers and not being able to add a tree fern or two to prehistoric scenes is going to disappoint a lot of model makers.

Wild Safari Prehistoric World Tree Fern – Gone to Seed

With Everything Dinosaur having received news of the demise of the tree fern it seems likely that the cycad and the agathis conifer models could have their days numbered too. We are still able to source these two prehistoric plants but we suspect that remaining stocks will soon be exhausted.

Toob Strike

The hand-painted designer toob product line is also having a bit of a sort out. Team members at Everything Dinosaur were sad to see the excellent prehistoric crocodiles toob retired a little while ago and now we hear that the prehistoric sharks and the prehistoric sea life toobs are also being withdrawn from production.

Prehistoric Sea Life and Prehistoric Sharks Scuttled

Prehistoric Animal Model Retirements

These two toobs contained a number of replicas not found in mainstream prehistoric animal model production. For example, in the prehistoric sharks toob there were models of Cretoxyrhina, Hybodus and Xenacanthus, whilst in the prehistoric sea life toob we know that collectors will miss the Metriorhynchus and the Basilosaurus replicas. Credit to Safari Ltd for bringing out these models in the first place and we do understand, that in order to introduce new figures some older models, inevitably have to be retired.

For more rare and difficult to obtain models visit Everything Dinosaur’s website: Everything Dinosaur.

Everything Dinosaur will have stocks of these items for a while yet, our advice is simple, purchase whilst you can if you want to add any of these to your model collections. As these items get rarer and more difficult to obtain, expect prices to rise on auction sites as dealers get greedier and greedier.

The Frankfurter Buchmesse (19th to 23rd October)

For many teachers, the half-term holiday provides an opportunity to review the scheme of work undertaken in the first part of the autumn term as well as to fine tune plans for the second part of the term and the build up to Christmas. However, for members of the teaching team at Everything Dinosaur, the pause in their programme of dinosaur and fossil themed workshops for schools, provides an opportunity to visit the forthcoming Frankfurt Book Fair.

Providing Inspiration for Teachers and Education Professionals

This annual five-day event, held in southern central Germany, attracts visitors from all over the world. It is the ideal venue for teachers, school administrators, educationalists and librarians to catch up on the latest trends in educational publishing.

Since Everything Dinosaur team members focus mainly on working with Key Stage One and Key Stage Two pupils, we appreciate the tremendous focus placed on the development of reading by teachers and teaching assistants. We may specialise in delivering fossil and dinosaur themed workshops in support of the science curriculum, but our teaching team also strives to ensure that they build in extension exercises that involves reading both non-fiction and fiction texts.

More than 250,000 Visitors are Expected at the 2016 Frankfurter Buchmesse

Developing a Passion for Reading

Developing confidence with reading is a fundamental element of the new English national curriculum for schools. In the Department of Education outline, the focus on providing children with a rich and stimulating learning environment is stressed and the school library can often provide a focal point for a coordinated effort across the school to improve reading. Many young boys become disillusioned with reading, however, if given the opportunity to read and then write about a Tyrannosaurus rex most jump at the opportunity.

As the world’s largest book fair (in terms of the number of publishers attending and exhibitors), the annual Frankfurter Buchmesse can inspire teachers, home educationalists and education professionals, allowing them to keep up to date with the fast moving world of educational publishing.

Did a Comet Aid the Rise of Mammals? That’s a Wonderful Question!

By Mike|2024-05-06T15:04:46+01:00October 16th, 2016|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Geology, Main Page|0 Comments

A Change in Sorting Tray Colour Leads to New Comet Conclusions

The idea that a period of rapid global warming that occurred some 56 million years ago was caused by an extra-terrestrial impact event has been postulated before. However, a team of American scientists, writing in the journal “Science” have published a new paper that supports the idea that a comet striking the eastern coast of North America may have played a role in a dramatic climate change, helping the rise of mammals.

The Rise of Mammals

A change that greatly benefited the Mammalia and helped to establish them as the dominate megafauna on our planet. Indeed, it could be argued that one group of mammals, the primates, did particularly well in the resulting “hot house Earth”, our ancient ancestors got a boost, which in the long-term contributed to our evolution.

For models and replicas of prehistoric animals including creatures from the Eocene: CollectA Deluxe Prehistoric Life Figures.

Fresh evidence to support the idea of a body from outer space crashing into Earth which resulted in a spike in global temperature (referred to as the Palaeocene-Eocene Thermal Maximum or the PETM for short), came when scientists switched from black sorting trays to white-coloured ones when examining drill core sediments from three sites located off the Atlantic coast of the United States.

“Hot House Earth”

The white sorting trays allowed the researchers to identify many more black-coloured, glassy, silica spherules (called microtektites). These objects suggest that there was some sort of high energy impact event, perhaps a six-mile wide comet crashing into the ocean. This would have instigated a rapid release of carbon dioxide into the atmosphere which led to global temperatures rising by around six degrees Celsius over the next thousand years or so.

As temperatures soared, great swathes of the planet became densely forested, the poles were ice free, thus providing a whole range of new habitats for the mammals to exploit.

Finding Microtektites

The tiny, glassy, tear-shaped or round objects, the microtektites have been found in marine sediments from three locations near to the stratigraphic level of the Palaeocene-Eocene boundary. The characteristics of these spherules are consistent with microtektites associated with debris caused during an extra-terrestrial impact.

Morgan Schaller, an Assistant Professor of Earth and environmental sciences at Rensselaer Polytechnic Institute, and corresponding author of the scientific paper, explained that the microtektites provide evidence of a catastrophic impact event having taken place.

He explained:

“This tells us that there was an extra-terrestrial impact at the time this sediment was deposited, a space rock hit the planet. The coincidence of an impact with a major climate change is nothing short of remarkable.”

Assistant Professor Schaller was helped in the research by Professor Miriam Katz and graduate student Megan Fung, (Rensselaer Polytechnic Institute), along with James Wright and Professor Dennis Kent (Rutgers University).

The Impact from a Comet

Professor Kent first postulated the idea that a comet impact could have led to the release of large amounts of CO2 that resulted in climate change back in 2003. He based his theory on magnetised clay particles found in New Jersey that he proposed were altered by the space impact. However, his views have been challenged by a number of other scientists. The idea of a comet striking the Earth has gained further credence following the discovery of relatively large amounts of microtektites from the Palaeocene-Eocene boundary. These objects could have formed when molten material flung out by the impact solidified in mid-air.

Black Trays and White Trays

The researchers were searching for micro-fossils in the drill cores (Foraminifera). Assistant Professor Schaller was the first to notice a microtektite in the sediment he was studying. Microtektites have not been found in Palaeocene-Eocene boundary strata in previous studies.

Schaller and his team suggest that this is so as microtektites being typically black are very difficult to spot against the dark colour of sorting trays. When the sediment from the cores was put into white sorting trays the team were able to identify many more. At peak abundance, the research team found as many as three microtektites per gramme of sediment examined.

Comets are known to contain a lot of carbon, an impact from a comet would release a lot of carbon dioxide, the lack of any iridium layer makes an impact from a rocky body such as an asteroid less likely. Hence the suggestion that a comet hit the Earth some 56 million years ago.

Doubts Expressed

A number of scientists remain sceptical with regards to this idea. The size of the microtektites has been noted. They are all extremely small. Professor Christian Koeberl, of the University of Vienna is an impact specialist and although he was not involved in this study, he states that the size of the spherules suggests that either they came from a long way away or that they were produced from a rather small impact event, one that would not have had the power to influence the global climate.

It is also possible that the particles may have been displaced from their original deposition, in the absence of dating information it cannot be confirmed that the microtektites come from the Palaeocene-Eocene boundary.

Rapidly Rising Temperatures May Have Helped the Evolution and Radiation of Primates

This is an intriguing paper, an extra-terrestrial impact very probably played a role in the ending of the “Age of Reptiles”, now it is suggested that ten million years later another impact event provided a stimulus to the radiation and diversification of the mammals.

Families Find Fossils of a Cretaceous “Swordfish”

By Mike|2023-05-08T09:58:04+01:00October 15th, 2016|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page|0 Comments

Australopachycormus hurleyi – Rare Fossils Found

The fearsome marine reptiles that once inhabited the Western Interior Seaway of North America led to this shallow, Cretaceous-age, inland sea being described as “Hell’s Aquarium”, but at the same time much of the land we know now as Australia was covered by an equally dangerous marine environment.

Amongst the myriad of marine reptiles, cephalopods and other exotic creatures, a three-metre fish with a head like a swordfish and dagger-like teeth swam. Thanks to two sharp-eyed families scientists have more fossils of this fast-swimming predator to study.

The Importance of Amateur Fossil Hunters

It is thanks to two families that scientists have some more of these extremely rare fossils to study. Australopachycormus was a member of an extinct, diverse group of fishes called the Pachycormidae, first described in 2007 from fossils found some several hundred kilometres south-west of the new discoveries.

This group of fish, believed to be basal to the teleosts, evolved into a number of forms including plankton-eating giants such as Bonnerichthys and Leedsichthys. Australopachycormus hurleyi was the first of the Pachycormidae to have been found in Early Cretaceous sediments in the Southern Hemisphere, it was not a gentle filter feeder, it would have been a fast swimming, active pursuit predator most likely preying on smaller fish species.

To read an article from 2010 that looks at some of the giant members of the Pachycormidae: Giant Bony Fish Swam in Prehistoric Seas.

An almost complete snout (rostrum) was found by the Johnston family and then, about a week later, the Amos family were walking in the same area and they discovered elements from the skull, backbones, teeth and portions of the front fins.

A spokesperson from Everything Dinosaur commented:

“Tourists and amateur fossil hunters have made a huge contribution in this part of the world. Fossils are often brought to the surface as agricultural machinery prepares the soil for crops and it is thanks to keen-eyed walkers that many rare and scientifically significant fossils have been found.”

Dr Patrick Smith, the curator of Kronosaurus Korner explained that thanks to these two families an outline of the skull, the anterior part of the body and that long sword-like rostrum had been assembled.

Dr Smith stated:

“We know that it was a high-tier carnivore and that it ate other large, fast-moving fish, a bit like marlin do today. Because it does fit that swordfish-like shape we know he [Australopachycormus] probably lived in that same ecological niche”.

The bony rostrum would have been used as a weapon to stun potential prey before they were snapped up in those formidable jaws. Dr Smith said he wanted to encourage other amateur palaeontologists and tourists to make their way to the tiny outback township of Richmond, as there were plenty of other amazing fossils just awaiting discovery.

What Does Australopachycormus hurleyi mean?

Whilst compiling this article Everything Dinosaur was emailed and asked how this ancient fish came to be called Australopachycormus hurleyi? The genus name reflects the fact that despite being a very numerous group of prehistoric fishes, Australopachycormus was the first Early Cretaceous pachycormid to be found in strata from the Southern Hemisphere. The genus name means “southern pachycormid”. The species name honours Tom Hurley who found the holotype material near Boulia in central, western Queensland when exploring the Toolebuc Formation of the Rolling Downs Group (Eromanga Basin).

So, if the Western Interior Seaway is known as “Hell’s Aquarium” we shall have to think of a suitable colloquialism to use when describing the marine biota of Queensland during the Cretaceous.

Suggestions would be most welcome.

Countdown to the Frankfurt Book Fair

By Mike|2023-05-08T09:49:58+01:00October 14th, 2016|Book Reviews, Main Page, Press Releases|0 Comments

One Week Until the Frankfurt Book Fair

Just under a week to go now until the grand opening of the Frankfurt Book Fair (19th-23rd October). The “Frankfurter Buchmesse” is the world’s largest trade fair for books and publications, based on the number of print houses and publishing companies that exhibit in the vast and sprawling trade halls. More than a quarter of a million visitors are expected to attend and for teaching professionals and for those responsible for book procurement for schools, this event provides a wonderful opportunity to catch up on the latest trends within educational publishing.

Over the course of the five-day event, the city of Frankfurt’s population could swell by us much as 20% as visitors from all over the world flock to, for what is for many, the centre of the book publishing world.

After all, this part of southern central Germany can trace its roots in the printing industry back some five centuries or more. The first three days are allocated to trade visitors, on the weekend, members of the public are able to attend and meet the many thousands of exhibitors, from over 100 different countries, many of who are specialists in the field of educational publishing.

Literacy and the English National Curriculum

When the Department of Education outlined the new curriculum for schools, it placed a great emphasis on reading skills and the development of language. Everything Dinosaur team members work mainly with Key Stage 1 and Key Stage 2 teaching teams and within the blueprints for the new curriculum’s roll out, the Dept. of Education stated that reading helps pupils to develop emotionally, culturally, intellectually, socially and spiritually.

Within our own workshops for schools, especially when working with Key Stage 1 classes, we try to build in extension exercises that involve the children exploring both non-fiction and fiction texts.

We may live in a society increasingly dominated by downloads, catch-ups and re-winds but it is through reading that children can acquire knowledge and build upon what they already know. Young boys can become disillusioned about reading, however, when given the chance to read a book all about dinosaurs they relish the opportunity.

The Aim of Many Teachers to Develop a Lifelong Appreciation of Books

Time for browsing at the Frankfurt Book Fair.

The Frankfurt Book Fair is considered by many as being the most important event of its kind in terms of international deals and trading. However, teachers and administrators responsible for the school library can also find much to inspire them and assist them with their work.

The school library is often a hub of learning within the school and provides a valuable focal point for developing a coordinated reading policy throughout the educational establishment. Such a library represents the very first place where children encounter a multitude of books for the very first time. It has been reported that the average UK household contains only around 150 books in total, so a well-stocked school library can appear like a magical “Aladdin’s Cave” to eager young readers.

The Reading Socio-economic Divide

In a survey carried out by the charity Booktrust and published in the early months of 2014, the socio-economic divide between readers and non-readers within the UK was highlighted. Based on a survey of fifteen hundred adults, the researchers found that on average, the better-off the person the more likely they were to read regularly. Key links were identified between a person’s propensity to read and their social background.

A high proportion of people from low income groups admitted that they never read. Young people, especially men with a relatively poor education, were the least likely to read regularly. The Dept. of Education concluded in its framework document for the future direction of the English national curriculum by stating that the skills of language are essential to participating fully as a member of our society.

People who do not learn to speak, read and write fluently and confidently are effectively disenfranchised.

All praise to the Frankfurt Book Fair and to the many teachers, home educationalists and education professionals who are inspired by what they see (and read) there.
