Siberian Villager Finds Steppe Mammoth Remains

By | August 31st, 2017|Dinosaur and Prehistoric Animal Drawings, Dinosaur and Prehistoric Animal News Stories, Main Page|0 Comments

A Mammoth in the Vegetable Patch

Everything Dinosaur has been informed about an article recently published in the “Siberian Times” reporting that a resident of the small and relatively remote village of Oy, in the Sakha Republic of north-eastern Russia, has found the fossilised remains of a Steppe Mammoth (M. trogontherii).  The local man was hoping to plant cabbage and potatoes in their vegetable patch.  Instead the digging uncovered the substantial tusks of a long-extinct member of the elephant family.

The Steppe Mammoth

The newspaper reports that the tusks measure 2.7 metres in length and at their base they are around 50 centimetres in diameter.  Palaeontologists and a regional historian, Prokopiy Nagovitsyn, were called in to assess the villager’s fossil discovery.  Officials are quoted as estimating the tusks at around 400,000-years-old.

Not Revealing the Exact Location of the Fossil Find

The historian (Prokopiy Nagovitsyn), explained that due to “understandable reasons”, the exact location of the fossil find was not being revealed.  If the location was known, this might attract unscrupulous ivory hunters who might attempt to steal the valuable tusks or they might be tempted to start their own excavations.

The vegetable patch discovery is described as “an extraordinary fossil find”.  Numerous Woolly Mammoths (Mammuthus primigenius), specimens are known from the Sakha Republic, the finding of the fossilised remains of a much more ancient Steppe Mammoth is a much rarer event.  Steppe Mammoths predate the Woolly Mammoth by hundreds of thousands of years.  Larger than M. primigenius, probably the largest of the Mammoth family, with adult males estimated to have weighed as much as fifteen tonnes, the Steppe Mammoth roamed Siberia from around 600,00 years ago to as recently as 370,000 years ago.

Everything Dinosaur stocks a large range of Ice Age models.  These models include a variety of prehistoric elephants and other ancient mammals.

In 2015, an almost complete fossil skeleton of a Steppe Mammoth was discovered in the same region of Russia.  The Steppe Mammoth is believed to have evolved from the southern, ancestral Mammoth (Mammuthus meridionalis).

The Oldest Elasmosaurid in Town

By | August 30th, 2017|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page|0 Comments

A New Basal Elasmosaurid is Described (Lagenanectes richterae)

It has been a busy week for Sven Sachs of the Bielefeld Natural History Museum, Germany.  A few days ago, Everything Dinosaur blogged about the discovery of the largest Ichthyosaurus specimen known (I. somersetensis), Sven was a co-author of the scientific paper published in the “Acta Palaeontologica Polonica”.  Today, we feature another marine reptile discovery, this time it concerns one of the oldest-known members of the Elasmosauridae and Sven is one of the co-authors of this paper too.

A Marine Reptile Discovery

Writing in the “Journal of Vertebrae Paleontology”, the researchers Jahn Hornung and Benjamin Kear as well as Sachs, describe a previously unrecognised new species of elasmosaur from Lower Cretaceous sediments at Sarstedt near Hannover (northern Germany).  The Elasmosauridae are a diverse family of plesiosaurs that are characterised by the extraordinarily long necks, with some specimens having more than seventy cervical vertebrae.  They were predominately piscivores, preying on small fish and squid, which they swallowed whole.

Older definitions of the Elasmosauridae included many Jurassic long-necked forms, however, most palaeontologists now restrict elasmosaurids to just the Cretaceous taxa.

The fossilised bones of the marine reptile were unearthed in 1964 as workmen were excavating a clay pit near the town of Sarstedt.  The fossils consist of a partial skull (cranium and mandible), the atlas-axis complex, additional cervical vertebrae, caudal vertebrae, an ilium, and limb elements.  The material was added to the vertebrate fossil collection of the Lower Saxony State Museum (Hannover), where it remained until scientists were recently invited to make a formal examination of the specimen.

Lead author of the study, Sven Sachs stated:

“It was an honour to be asked to research the mysterious Sarstedt plesiosaur skeleton.  It has been one of the hidden jewels of the museum and even more importantly, it has turned out to be new to science.”

“Lagena Swimmer”

This basal elasmosaurid lived around 132 million years ago (Hauterivian faunal stage of the Lower Cretaceous), it has been named Lagenanectes richterae.  The genus name is the Latinised form of the Leine River, which flows through the townscape of Sarstedt.  The species name honours Dr Annette Richter, (Chief Curator of Natural Sciences at the Lower Saxony State Museum), who facilitated documentation of the fossil.  Dr Richter also makes a handy scale reference in the drawing (above), L. richterae is estimated to have been around eight metres in length.  The skull of Lagenanectes will be displayed as a centrepiece in the “Water Worlds” exhibition at the Lower Saxony State Museum.

Lagenanectes richterae

Co-author of the paper, Dr Jahn Hornung, a palaeontologist based in Hamburg said:

“Its broad chin was expanded into a massive jutting crest, and its lower teeth stuck out sideways.  These probably served to trap small fish and squid that were then swallowed whole.”

Internal channels in the upper jaws might have housed nerves linked to pressure receptors or electroreceptors on the outside of the snout that would have helped Lagenanectes to locate its prey.

Bones at the back of the skull and the atlas show evidence of a chronic bacterial infection (osteomyelitic infection).  This pathology is clearly visible in the fossil bones and this infection could have eventually claimed the animal’s life.

Dr Benjamin Kear (Museum of Evolution, Uppsala University, Sweden), who also contributed to the study, explained the significance of this Plesiosaur specimen:

“The most important aspect of this new plesiosaur is that it is amongst the oldest of its kind.   It is one of the earliest elasmosaurs, an extremely successful group of globally distributed plesiosaurs that seem to have had their evolutionary origins in the seas that once inundated Western Europe.”

New Species of African Titanosaur Described

By | August 29th, 2017|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page|0 Comments

Shingopana songwensis – Hinting at a Diverse African Titanosaur Biota

A team of international scientists including Dr Eric Gorscak, a recent PhD graduate of Ohio University and now a post-doctoral researcher at the Field Museum of Natural History (Chicago, USA), have identified a new species of Cretaceous long-necked dinosaur from south-western Tanzania.  This new species of plant-eating giant has been named Shingopana songwensis and its discovery helps to demonstrate how diverse the dinosaur fauna was in southern Africa during the Cretaceous.

Writing in the Journal of Vertebrate Palaeontology, the scientists, describe the new titanosaur, one that shows anatomical affinities to South American titanosaurs, indicating that Shingopana was more closely related to South American dinosaurs than it was to those species known from Africa.

The first fossils of this new dinosaur were found in 2002 by scientists affiliated with the Rukwa Rift Basin Project, an international effort led by Ohio University Heritage College of Osteopathic Medicine researchers Patrick O’Connor and Nancy Stevens.  Other elements associated with the specimen were found over the next two years.  All the fossils come from Namba Member of the Galula Formation.

In the beautiful illustration created by palaeoartist Mark Witton, (above), a herd of Shingopana can be seen in the background, whilst the foreground is dominated by the rotting carcass of S. songwensis.  A crocodylomorph is scavenging and the corpse has attracted the attention of numerous carrion beetles some of which can be clearly seen on an exposed rib bone.

The Enigmatic Galula Formation

The Galula Formation consists of a 600-3000 metre-thick sequence of amalgamated, braided fluvial deposits that were deposited across an extensive braidplain system via multiple parallel channels that had their source in the highlands of Zambia and Malawi.  Dating these mainly sandstone sediments has proved challenging.  Magnetostratigraphic studies place these deposits, split into two main members (the Namba and the geologically older Mtuka members), as being no older than mid-Late Cretaceous (Turonian-Campanian) for the Namba and constraining the Mtuka to the Middle Cretaceous (Aptian – Cenomanian).  Although most of the vertebrate fossils discovered to date are fragmentary in nature, they hint at a rich biota made up of numerous crocodyliforms, turtles, theropods, sauropods plus evidence of several types of small mammal.

The fossils represent around 10% of the total skeleton.  They were excavated from a single location and the fossils were disarticulated.  A comparison of the left humerus to that of the contemporaneous but not closely related Malawisaurus suggests that Shingopana might have exceeded 16 metres in length, although other media sources report that this dinosaur was under ten metres in length.  Other fossils include part of the jaw (left angular), part of the hip girdle, cervical and dorsal ribs along with neck bones (cervical vertebrae).

“Wide Neck” from the Songwe Region

The name of this new dinosaur (Shingopana songwensis), is derived from the local Swahili term “shingopana” for “wide neck”.  The neural spine of the cervical ribs show a bulbous expansion, that led the researchers to assign this new genus to the Aeolosaurini, all the dinosaurs assigned to this clade (as far as we at Everything Dinosaur know), come from South America.  The trivial name honours the location of the discovery, the Songwe region of the Great Rift Valley.  Shingopana is the first African titanosaur that is closely related to Aeolosaurines.

Shingopana Fossil Bones Being Excavated and Prepared for Field Removal

Commenting on the phylogeny of Shingopana, Dr Gorscak stated:

“There are anatomical features present only in Shingopana and in several South American titanosaurs, but not in other African titanosaurs.  Shingopana had siblings in South America, whereas other African titanosaurs were only distant cousins.”

This discovery supports the hypothesis that the biota of southern and northern Africa were very different during the Cretaceous.  Dinosaurs from the southern part of the continent were probably more closely related to South American dinosaurs than they were to the dinosaurs that lived on the northern part of Africa.  Shingopana co-existed with another titanosaur, Rukwatitan bisepultus, but just like Malawisaurus, Rukwatitan was not closely related to Shingopana.

Dinosaur CSI

The researchers noted that the bones had been weathered prior to fossilisation.  The fossils show extensive borings, most likely caused by the activities of carrion beetles.  The presence of these trace fossils are particularly notable on the cervical vertebrae, the humerus and the pubis.  Over 150 separate bore holes were identified on 10 different bones from the dig site.  Insect borings such as these give palaeontologists an opportunity to reconstruct the timing of death and the taphonomy (the fossilisation process), of the fossil material.

A Changing Cretaceous Landscape

As the super-continent of Gondwana began to break up, so Madagascar and Antarctica split from the landmass that we now know as southern Africa. This was followed by the gradual northward “unzipping” of South America.  Northern Africa maintained a land bridge with South America, but southern Africa slowly became more isolated until the continents completely separated around 105 – 95  million years ago.

Other factors such as terrain and climate may have further isolated southern Africa.  The discovery of Shingopana highlights the different regional faunas between north Africa and southern Africa and suggests that tectonically driven separation of the landmasses may have influenced the development of progressively isolated southern African faunas throughout the Cretaceous.

Palaeontologists and the Pregnant Ichthyosaurus

By | August 28th, 2017|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page|0 Comments

Largest Ichthyosaurus on Record Springs a Couple of Surprises

A team of scientists from the UK and Germany have discovered the largest Ichthyosaurus known to science, what’s more, the specimen was pregnant at the time of its demise some 200 million years ago.  In addition, the fossilised marine reptile, part of a collection at the Lower Saxony State Museum (Hannover, Germany), turned out to be a chimera.  The specimen did not represent two ichthyosaurs (mum and the baby), but actually three!  There’s a twist in this tale.

Ichthyosaurus somersetensis Specimen in the Study

Largest Ichthyosaurus

The new specimen is estimated to be between three and three and a half metres long.  It is an adult female.  The Ichthyosaurus genus consists of a number of species, several of which have been named and described in the last two years, with palaeontologist Dean Lomax of Manchester University, one of the authors of this new study, playing a prominent role in the description of Ichthyosaurus anningae (2015), I. larkini and I. somersetensis (both 2016).

The very first Ichthyosaurus species to be erected was Ichthyosaurus communis, that took place way back in 1822, thanks to the fossil finding exploits of Mary Anning.  Lots of Ichthyosaurus fossils have been collected, mostly from Lower Jurassic rocks of Europe, as a result, this genus is the best known of all the ichthyosaurs.

Not the Biggest Genus in the Ichthyosauria

Ichthyosaurus is so well known in the scientific community that the Order to which this genus belongs (Order Ichthyosauria), was named after Ichthyosaurus.  Most fossil examples of Ichthyosaurus show specimens of around two metres in length, this specimen was considerably larger, making it the largest Ichthyosaurus on record, although it would have been dwarfed by other members of the Ichthyosauria – giants such as Himalayasaurus and Shonisaurus that grew to lengths in excess of fifteen metres.

This fossil specimen was originally discovered on the Somerset coast, sometime in the mid 1990s.  It remained unstudied until it ended up in the vertebrate fossil collection of the Lower Saxony State Museum.  Co-author of the scientific paper, published in “Acta Palaeontologica Polonica”, Sven Sachs (Bielefeld Natural History Museum, Germany), first examined the fossil in August 2016, whilst on a routine visit to Hannover.  He contacted Dean Lomax and the two scientists set about investigating just what the fossil actually represented.

The pair identified the fossil as an example of Ichthyosaurus somersetensis, a species that Dean and another colleague, Professor Judy Massare (Brockport College, New York), had named a year earlier.

Dean Lomax commented:

“It amazes me that specimens such as this [the biggest] can still be ‘rediscovered’ in museum collections.  You don’t necessarily have to go out in the field to make a new discovery.  This specimen provides new insights into the size range of the species, but also records only the third example of an Ichthyosaurus known with an embryo.  That’s special.”

Ichthyosaurus Embryo

The embryo is incomplete and preserves only a portion of the back bone (vertebrae), a forefin, ribs and a few other bones.  The preserved string of vertebrae is less than 7 centimetres in length.  The bones of the embryo are not fully ossified, indicating that the embryo was still developing, when it and its mother perished.

Not the Right Tail

Dean and his co-author Sven, also made another intriguing discovery.  The tail of this newly described specimen did not belong with the rest of the fossil skeleton.  The rear portion of another ichthyosaur had been added, probably to make the exhibit more visually appealing.  As well as being an expectant mother this Ichthyosaurus turned out to be a chimera.

Sven added:

“It is often important to examine fossils with a very critical eye.  Sometimes, as in this instance, specimens aren’t exactly what they appear to be.  However, it was not ‘put together’ to represent a fake, but simply for a better display specimen.  But, if “fake” portions remain undetected then scientists can fall foul of this, which results in false information presented in the published record.”

Sven Sachs went onto state:

“Specimens like this provide palaeontologists with important information about when these animals lived.  Many examples of Ichthyosaurus are from historical collections and most do not have good geographical or geological records, but this specimen has it all.  It may help to date other Ichthyosaur fossils that currently have no information.”

Ceratopsian Cladogram

Piecing Together the Horned Dinosaur Family Tree

Plans are in place at Everything Dinosaur to create a pdf file that highlights the evolution, radiation and diversity of the Ceratopsia.  The aim is to use the numerous illustrations of horned dinosaurs that the company has built up in its extensive database to produce a simplified horned dinosaur family tree.

Dinosaur fans will be aware that over the last two decades, the number of formally described ceratopsid dinosaurs has increased significantly, mostly due to the number of new Late Cretaceous horned dinosaurs named from fossil discoveries in the United States and Canada.  Model collectors will also know that there have been several new horned dinosaur models introduced over the last few years.  This trend is set to continue.  For every named prehistoric animal model that Everything Dinosaur supplies, we send out an accompanying fact sheet with that figure.  In this way, our own image library for the ceratopsids has dramatically increased.

Centrosaurine and Chasmosaurine

Traditionally, whilst the Ceratopsia includes numerous basal horned dinosaurs, the Ceratopsidae family, has been classified into two sub-families based on cranial ornamentation and horn morphology -the Centrosaurinae and the Chasmosaurinae.  The large horned dinosaurs of the Late Cretaceous period, specifically the Ceratopsidae, were all quadrupedal with heavy, armoured heads.  Palaeontologists used a simple method of assigning these types of dinosaurs to a sub-family:

  • Centrosaurines – short neck frill with a large nose horn, bigger than the brow horns.  This very simplistic description does not mean that centrosaurines had short frills.  Most frills were ornamented and in the case of the centrosaurine Styracosaurus – spectacular.

  • Chasmosaurines – long neck frill with long snouts and the brow horns were usually bigger and more prominent than the nasal horn.

A Ceratopsian Cladogram

As with most things related to palaeontology, the rather simplistic classification of centrosaurines and chasmosaurines has been undermined as new discoveries have been made.  A case in point, is the recently described Regaliceratops (see picture above).  It is for this reason that Everything Dinosaur team members are wanting to create their own cladogram.

We need some more illustrations to complete our data set, but once these have been commissioned we shall post up our own version of the horned dinosaur family tree.  It might be interesting to populate one cladogram using our own dinosaur illustrations, a second, identical phylogenetic analysis can be produced, but this time using the actual models to illustrate the various taxonomic positions.  It’s still a work in progress at the moment, but hopefully, we shall be able to produce something in the near future.

Colourful Dinosaur Drawing

As August draws to a close and our teaching team turn their thoughts to the start of the new term.  Team members were sent a colourful dinosaur drawing.  It brightened our day.  We might have to spend much of our weekend planning (just like most teachers), but at least this lovely, colourful dinosaur drawing sent into our offices cheered us all up.

The artist did not give their dinosaur creation a name so we have called this prehistoric animal “Rainbowsaurus”.  With his red, yellow, bright orange and green colouration this is one dinosaur that would have had no trouble standing out from the rest of the flock.  Dinosaurs did have (in all likelihood), colour vision, so some species may have been very brightly coloured indeed.   As for that huge, custard-coloured, dinosaur, it might not be as fanciful as it first appears.  A duck-billed dinosaur from China may have possessed a very similar looking horn, the dinosaur is called Tsintaosaurus.

The Diversity of Early Cretaceous Feathered Theropods

By | August 26th, 2017|Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Main Page|0 Comments

Wonderful Early Cretaceous Theropod Dinosaur Illustration

Sometimes at Everything Dinosaur, we get asked fascinating questions.  For example, we were emailed this week by a fossil collector asking how many different types of feathered dinosaur were there?  That’s a question, the answer to which, as new fossil discoveries are made, keeps changing.  Since the discovery of Sinosauropteryx in 1996 and its subsequent scientific description, numerous feathered dinosaur fossil discoveries have been made.  In all likelihood, within the Theropoda alone, there were probably hundreds of different types of feathered dinosaur.

Feathered Theropods

The diversity of the feathered theropods is beautifully illustrated in a wonderful image created by Jan Slovak.

The famous Jan Slovak image depicts part of the Liaoning biota of the Early Cretaceous.  The picture illustrates a variety of different types of feathered dinosaurs, (all Coelurosaurian dinosaurs).  A pair of Sinosauropteryx (right), chase a small mammal.  Sinosauropteryx is an example of a compsognathid theropod.  To the left, two Microraptors pursue a dragonfly.  Microraptors come from another branch of the Coelurosauria clade, the dromaeosaurids, sometimes referred to as the “raptors”.

In the background, an ornate couple of dinosaurs are displaying to each other.  They are conducting an intricate courtship display and are oblivious to what is going on around them.  This is a pair of Caudipteryx dinosaurs, complete with beautiful tail plumes.  Caudipteryx is yet another example of a type of feathered theropod.  Caudipteryx is a member of the oviraptorosaurian group.

Chinese Stegosaurs

By | August 25th, 2017|Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Everything Dinosaur Products, Photos of Everything Dinosaur Products|0 Comments

Stegosaurs from China

With the addition of the PNSO Age of Dinosaurs model range to the Everything Dinosaur portfolio, we have had to increase the number of Stegosaur illustrations in our database.  The Dashanpu Formation (Sichuan Province, south-western China) has produced a large number of stegosaurian fossil remains and a number of genera have been erected. The majority of the specimens have been found in the Upper Shaximiao Formation, but the Lower Shaximiao Formation has also yielded thyreophorans, notably Huayangosaurus, which led to the establishment of the Huayangosauridae family, to which the later Chungkingosaurus has been assigned.  There are lots of Chinese stegosaurs.

There are members of the Stegosauria clade in the PNSO Age of Dinosaurs large models, an example of which is Chungkingosaurus, illustrated in the line drawing above.  In addition, the smaller models, the PNSO Age of Dinosaurs Toys include a number of armoured dinosaur representatives.  Four of the twenty-four models in this series are Stegosaurs, namely Kentrosaurus, Wuerhosaurus, Miragaia and Tuojiangosaurus, but surprisingly, despite the inclusion of an Ankylosaurus, there is no Stegosaurus, arguably the best-known of all the Stegosauridae, currently in this range (yet).  However, it is good to see Chinese stegosaurs represented.

An Asian Origin for Stegosaurs?

Such was the diversity of stegosaur fossil remains from the Sichuan Province (south-western China), that it had been thought that the stegosaurs evolved in Asia.  A review of the fossil material undertaken in 2006* reassessed the seven named genera of stegosaur based on fossil material from the Upper Jurassic of China.  These Chinese fossils represented a diversity of stegosaurs not found anywhere else in the world during the Late Jurassic.  The researchers concluded that only Tuojiangosaurus multispinus, Chungkingosaurus jiangbeiensis and Gigantspinosaurus sichuanensis were valid taxa and therefore, the origin of the Stegosauria remained uncertain.

A spokesperson from Everything Dinosaur commented:

“It is wonderful to see more stegosaur figures and the PNSO Age of Dinosaurs stegosaurs are in danger of selling out, however, we intend to bring in more stocks soon.  It is refreshing to see some of the lesser-known taxa being represented in an affordable model range.”

The spokesperson went onto state that a number of new illustrations has recently been commissioned and that more drawings would be added to Everything Dinosaur’s database in the near future.  The company receives lots of dinosaur and prehistoric animal drawings from dinosaur fans and they would be particularly interested to receive illustrations of armoured dinosaurs.
