Another busy day for Everything Dinosaur’s teaching team. One of our dinosaur and fossil experts had been invited to a school in south Yorkshire to help the Nursery and Reception classes kick-start their term topic learning all about prehistoric animals. The enthusiastic children enjoyed the workshops and had fun handling the fossils, several of them talked excitedly about it for the rest of the day.
We were given the spacious hall to set up in and we noted that on one of the walls, there was a display of prehistoric animals that had been created by some of the children at the school.

Extension Resources
Prior to the start of our workshops we were briefed on the learning needs of the children by one of the teachers. The classes had only been studying dinosaurs for a week, but they had prepared some amazing questions for our dinosaur expert to tackle. As well as delivering four workshops throughout the day, we donated some dinosaur books to the school library and provided some additional teaching resources to help support the scheme of work for the school term.
We are confident that our “dinosaur hokey cokey” will be well received by the eager, young palaeontologists.
We were also able to email over some dinosaur fact sheets and additional drawing materials to help support the Reception classes with a little challenge that we had set them.
Our congratulations to all the budding palaeontologists in Sooty Owls class (Foundation Stage 2), at Laithes Primary in south Yorkshire for compiling such a fascinating set of questions about dinosaurs. The children in Foundation Stage at this Barnsley school have just started their summer term topic and they are very excited to be learning about dinosaurs and life in the past.
Questions About Dinosaurs
Questions Compiled by Sooty Owls for Everything Dinosaur
The children in the Sooty Owls class have compiled a set of questions about dinosaurs.

Why do Dinosaurs Roar?
Sophie asked why do dinosaurs roar? This is a very difficult question to answer as we don’t have a living Tyrannosaurus rex, Stegosaurus or any other non-avian dinosaur to study. Dinosaurs certainly do a lot of loud roaring in movies like “Jurassic Park”, but it is hard to work out what sort of sounds they made by just studying the fossilised bones alone. Having said that, the tiny bones of the inner ear that have been found have given palaeontologists some ideas as to the sort of sounds that these animals might have heard.
Dinosaurs seem to have had good hearing so they probably did make some sounds, perhaps some of the smaller dinosaurs might have chirped like their near relatives the birds. Other dinosaurs might have squawked, twittered or clucked, whilst very big dinosaurs may have made low frequency rumbling sounds, the vibrations of which, could have been detected by their feet (elephants are believed to be able to detect low frequency sounds in this way).
Some Very Big Dinosaurs Could have Picked Up Sounds Using their Feet
Some very big dinosaurs could have picked up sounds using their feet.
When do Dinosaurs Sleep?
Emir wanted to know about dinosaur sleeping habits. He asked when do dinosaurs sleep? There are lots and lots of different types of dinosaurs and some of them were probably nocturnal (active at night), so these types of dinosaurs would have slept during the day. Can the children in Sooty Owls class make a list of animals alive today that are nocturnal? Most dinosaurs would have slept at night, just like we do, but all dinosaurs would have probably napped from time to time to.
Palaeontologists have found fossils of sleeping dinosaurs. Some dinosaurs may have slept with one eye open so that they could stay safe.
A Sleeping Dinosaur (Mei long)
Did dinosaurs sleep with one eye open?
The fossils of the dinosaur from China called Mei long, suggest that some dinosaurs slept like birds. The name Mei long means “sleeping dragon”.
Were Dinosaurs Cold-blooded?
Tyler asked were dinosaurs cold-blooded? Reptiles that are alive today, animals like snakes, lizards and crocodiles, have to rely on external sources of heat to help them keep warm and active. Reptiles bask in the sun, using the heat from the sun to warm their bodies. It is likely that most dinosaurs, which were probably much more active than snakes and crocodiles, were not cold-blooded, that is, they could have maintained a body temperature that was warmer than their surroundings.
Many dinosaurs had feathers and these feathers helped trap body heat to keep these dinosaurs from getting too cold.
Some dinosaurs lived in Antarctica and some dinosaurs lived in the Arctic Circle, so they would have been well-used to chilly conditions. Mammals and birds are warm-blooded, birds are very closely related to dinosaurs.
Warm-blooded or Cold-blooded Dinosaurs?

Would a T. rex Bite My Arm?
Rayen wanted to know about Tyrannosaurus rex and asked the following question – would T. rex bite my arm? Tyrannosaurus rex was a meat-eating dinosaur, if it was around today, then a T. rex might indeed try to eat you. T. rex was so big that he could have eaten everyone in Sooty Owls class for dinner and eaten the class teacher for dessert. A fully-grown T. rex would have been capable of swallowing Rayen in one big bite! It is reassuring to know that these types of dinosaurs, known as the non-avian dinosaurs are extinct!
Our thanks once again to the children in Sooty Owls class for compiling such a wonderful set of dinosaur themed questions.
The Pneumatic Bones of Theropods (Living and Extinct)
Air-filled (pneumatic), bones are unique to birds amongst living terrestrial vertebrates. However, it is known that many different types of archosaurs as well as the birds had post-cranial bones with lots of air sacs. Non-avian dinosaurs in the form of the Theropoda had them to. Whilst visiting the Grant Museum of Zoology and Comparative Anatomy in London, this shared anatomical trait was beautifully demonstrated when viewing a number of avian exhibits.

The caption in the display case reads:
“OSTRICH FEMUR – Birds have honeycomb bones to reduce weight for flight. Flightless ostriches evolved from flying birds and retain this feature”.
The above statement is true, but technically (most probably), pneumatic, post-cranial bones have been inherited from the Dinosauria.

Air-filled Bones Evolved Independently in Several Groups Avemetatarsalia
The fossil record has provided evidence of pneumaticity in Late Triassic archosaurs (at least 210 million years ago), it is very likely that air-filled bones evolved much earlier in the branch of the archosaurs (Avemetatarsalia), that includes the dinosaurs, pterosaurs and birds. Bones with air sacs are also associated with derived members of the Sauropodomorpha. It has been postulated that this characteristic evolved independently in several groups and that pneumaticity did not occur amongst these different archosaurs as a result of sharing a common ancestor.
The evolution of light, but strong air-filled bones can be explained for the birds, as such bones would help reduce weight and make flying easier. As for the other, extinct archosaurs, this characteristic evolved in the Pterosauria (flying reptiles) for very probably the same reason – to reduce weight to make flying easier. As for the dinosaurs and other largely non-volant archosaurs that had this feature, pneumatisation might have evolved to reduce energy expenditure as these animals moved about. After all, if you weigh several tonnes, as in the case of a basal sauropod, if you could evolve a more efficient method of locomotion, than this makes a lot of evolutionary sense.

“Fallen Kingdom” – Dinosaurs and Other Prehistoric Animals
In response to the numerous requests from young dinosaur fans who have seen the latest instalment in the “Jurassic Park/Jurassic World” film franchise – “Fallen Kingdom”, here is a list of the prehistoric animals that we spotted in the movie. In total, Everything Dinosaur team members spotted seventeen different prehistoric animals, how many did you see?
Hitting our Cinema Screens at Present – “Fallen Kingdom”
The movie poster features a Mosasaurus.
Everything Dinosaur’s List of the Prehistoric Animals in “Fallen Kingdom”
Allosaurus – a big, carnivorous dinosaur that lived during the Late Jurassic.
Ankylosaurus – an armoured dinosaur, a herbivore from the Late Cretaceous of North America.
Apatosaurus/Brontosaurus – a giant, long-necked plant-eating dinosaur from the Late Jurassic.
Baryonyx – a carnivorous dinosaur that may have specialised in catching fish, the first fossils of which were found in southern England. Baryonyx lived during the Early Cretaceous of Europe.
Brachiosaurus – an enormous, plant-eating, long-necked dinosaur from the Late Jurassic.
Carnotaurus – a predatory dinosaur from the Late Cretaceous of South America.
Compsognathus – at around a metre in length, the smallest non-avian dinosaur inhabitant of Isla Nublar. This little dinosaur lived in Europe during the Late Jurassic.
Gallimimus – a fast-running, “ostrich mimic” dinosaur that lived in Asia during the Late Cretaceous.
Mosasaurus – not a dinosaur, but a marine reptile that belongs to the same group of reptiles as lizards and snakes. These predators lived during the Cretaceous.
Pteranodon – also not a dinosaur, but a flying reptile from the Late Cretaceous, a pterosaur. Pteranodon fossils have been found in North America, England and Asia.
Sinoceratops – a member of the horned dinosaur group, it roamed China towards the end of the “Age of Dinosaurs”.
Stegosaurus – “roof lizard”, a herbivore from the Late Jurassic of America.
Stygimoloch – a “bone-headed” dinosaur from the Late Cretaceous of North America which was good at knocking down walls if the movie is to be believed!
Triceratops – one of the most famous of all the plant-eating dinosaurs. Triceratops lived at the very end of the Cretaceous. Its fossils have been found in North America.
Tyrannosaurus rex – no dinosaur film would be complete without an appearance of T. rex. The “king of the tyrant lizards”, lived in North America and its fossils are associated with Upper Cretaceous sedimentary deposits.
Velociraptor – The “raptor” called Blue which was reared and brought up by animal trainer Owen Grady (played by Chris Pratt). Velociraptor lived during the Late Cretaceous of Asia.
Last but not least, comes Indoraptor, a dinosaur created from the DNA from Indominus rex – the monstrous carnivore from the previous film in the franchise – “Jurassic World” and Velociraptor.
Look out for the sequel which is scheduled for release in June 2021. What dinosaurs do you think should be in this film?
Scientists Calculate the Cost of Powering a Dinosaur Theme Park
This week, twenty-five years ago, saw the release of the film “Jurassic Park”, the Steven Spielberg directed blockbuster that brought to the world’s cinema screens CGI generated and animatronic dinosaurs. As cinema-goers currently enjoy the latest instalment in this multi-billion-dollar franchise – “Fallen Kingdom”, we could reflect on how our perceptions regarding the Dinosauria has changed since the adaptation of Michael Crichton’s 1990 novel first hit our screens.
Celebrating Twenty-Five Years of Jurassic Park
The first edition of Jurassic Park published in 1990, Steven Spielberg’s blockbuster followed three years later.
Powering “Fallen Kingdom”
We could comment on how these movies have enthused a whole generation of new scientists, with many opting for a career in palaeontology, first inspired by the amazing prehistoric animals brought to life on the silver screen. Instead, let’s leave the speculation to others about whether it would ever be possible to resurrect a long extinct group of animals, the last of which roamed the Earth sixty-six million years ago and consider one of the more practical aspects of converting an island into a dinosaur themed tourist attraction – how much power would it take to run Jurassic Park?
Thanks to E.ON and the assistance of some very clever physicists at Imperial College London, we have an answer to this question.
It would take 455 million kWh to power a real-life Dinosaur Kingdom. That’s enough to power half the homes in Harrogate for a year. Furthermore, team members at Everything Dinosaur have calculated, that based on an average UK household’s power consumption of around 5,000 kWh per annum, the annual power consumption of your typical prehistoric animal populated park would permit you to run the average UK home for around 91,000 years! That should be enough gas and electricity to see you comfortably through the next Ice Age.

Running a Real-Life Jurassic Park
From a huge aquarium to house the semi-aquatic Spinosaurus to a dinosaur embryo cooling fridge and egg incubator, the physics experts investigated how much energy each feature would need to keep the park running over twelve months. The final figure calculated was 455,145,418 kWh, costing approximately £131,732 a day. We wonder how much money the owners of the theme park would have saved if they had instructed their geneticists to re-create dinosaurs as they probably were, that is, equipped with their own insulation in the form of downy, feathery coats.
If Feathered Dinosaurs had been Genetically Engineered – This Might Have Reduced the Annual Fuel Bill
If dinosaurs had been genetically engineered so that they retained their feathers, would insulated dinosaurs have reduced the annual fuel bill?

Modern Energy Solutions to Accommodate Ancient Animals
For any billionaire with aspirations to build a real-life “Jurassic Park”, having an understanding of the running costs would be an important component of the business plan.
Scott Somerville, E.ON’s Head of Advertising, PR and Campaigns, stated:
“With huge 10,000 volt electric fences and an aviary designed to house pterosaurs to name just two of the Dinosaur Kingdom’s unusual features, we suspected the energy needed to power the whole park would be big – possibly equivalent to powering a whole region within the UK. But what our figures show is that it’s actually a massive amount! It’s about the same as powering 30,142 average UK households a year – roughly equivalent to powering half the homes in Harrogate – but by adopting modern solutions, the power requirement and costs could be even less.”
Prehistoric Poo Turned into Power
The operators of any theoretical theme park, in which the main attractions would have quite happy consumed visitors for their breakfast, would need the very latest in safety features. There have been five films in the “Jurassic Park/Jurassic World” franchise to date and we all know what happens when things go wrong – it does not end well for the tourists. However, innovative and environmentally friendly methods of power generation could be adopted to keep those fences charged. The dinosaurs themselves could play a role in helping to keep running costs from mutating into monstrous proportions, as E.ON’s Scott Somerville went onto explain:
“By generating electricity using technology like a biomass fuelled Combined Heat and Power station, park owners could turn dinosaur droppings into electricity. Add on other solutions like solar and battery storage, then the park could ultimately benefit from a cheaper, sustainable and more reliable source of electricity instead having to deal with a ‘raptor rampage’ every time the generators that power the electric fences go down.”
For any would-be entrepreneurs with a few billion burning a hole in their pocket, further information on E.ON’s estimates of the running costs of a real-life dinosaur theme park can be found here: Dinosaur Kingdom Running Costs.
As for the rest of us, read the books, watch the movies, it is likely to be a lot less expensive and a good deal safer too.
If anyone or any organisation did really set out to create a dinosaur themed tourist attraction, populated by living, breathing, albeit genetically engineered prehistoric animals, then we suspect it would “spark” a Tyrannosaurus rex-sized debate. Feathers would be well and truly ruffled!
Yesterday, team members at Everything Dinosaur were able to take a break from their busy schedule and visit the cinema to watch “Fallen Kingdom”, the latest film in the “Jurassic Park/Jurassic World” franchise. We shall leave it to others to provide a review, but we were able to pass a couple of pleasant hours marvelling at how CGI and animatronics can bring about the resurrection of long extinct species.
Prior to the film starting we got talking to the friendly cinema staff. They were most interested in our work and as a result, one of the cinema staff members went into their office and returned with two posters. Free posters are being given out by certain cinema chains to help promote the movie, something that we were not aware of. Our posters feature a giant (somewhat oversized), Mosasaurus marine reptile feeding on a shark, a famous scene from the previous film “Jurassic World”.

Donating Mosasaurus Posters to a School
We thanked the staff for their gift of the posters, these will go to a good home. Everything Dinosaur has a school visit arranged for Wednesday of this week, delivering a series of dinosaur workshops to classes in support of their dinosaur and prehistoric animal themed term topic. We shall take these two posters with us and donate them to the school, perhaps the poster will help the children to remember that an animal like a mosasaur is not actually a dinosaur. The poster might even inspire them to have a go at drawing their very own prehistoric animals.
When Everything Dinosaur team members visit a school, we tend to bring extra resources to support the school’s scheme of work and during our dinosaur workshops, the opportunity usually arises to challenge the children to undertake some extension activities in support of the curriculum.
We suspect that these two “Fallen Kingdom” posters will be gratefully received and we are sure that they will help the classes to create their own colourful and informative dinosaur and prehistoric animal displays.
Professor Vince Gaffney, Anniversary Chair in Landscape Archaeology at the University of Bradford, has been honoured with the award of the MBE in the Queen’s 2018 Birthday Honours List. The award is for services to archaeology. Our congratulations to the professor.
Bradford University Professor Awarded MBE
Professor Gaffney is a world-renowned expert in archaeological landscape studies who, over the last four decades, has engaged with young and old, passionately presenting his subject matter as an exciting and thought-provoking study of people and their environments in the present and the past. He continues to attract tremendous international media interest and to inspire the next generation of aspiring archaeologists.
Honoured with the Award of an MBE – Professor Vince Gaffney (Bradford University)

Vince has been the recipient of numerous national and international awards. In 2017, his work in the Stonehenge landscape was awarded the “Research Project of the Year “ and he was recently shortlisted for Archaeologist of the Year by the journal “Current Archaeology”. Five years ago, he received the European Archaeological Heritage Prize and his work also received the prestigious Queen’s Award for Higher Education, for use of novel technology within the Wroxeter Hinterland Project, providing the first comprehensive geophysical survey of a major Roman town in Britain.
A Pioneer of New Research Techniques
Professor Gaffney has pioneered the application of computing in archaeology. His work on the Croatian Adriatic Islands provided the first substantial use of geographical information systems (GIS) in Europe. More recently, he has led the UK team creating three-dimensional and virtual imaging of the “Stonehenge Hidden Landscapes”, from an extensive programme of geophysical surveys of the largely unmapped landscape and which will change our understanding of Stonehenge and shape history as well as inform student teaching and learning.
His work on archaeological landscapes lost to the sea after the last glaciation received the 2007 award for Heritage Presentation at the British Association for the Advancement of Science. This research was also selected by Research Councils UK as one of top hundred ground-breaking UK research projects as part of its “Big Ideas for the Future” publication.
In 2010, Professor Gaffney’s book on this subject, “Europe’s Lost World”, was awarded the “Best Publication” prize at the British Archaeological Awards. Professor Gaffney and his colleagues were also invited to exhibit their work on underwater landscapes in the Royal Society’s Summer Science Exhibition.

Recently, Everything Dinosaur has featured the research into the hidden landscapes of the southern North Sea basin. This study funded by a European Research Council grant, represents one of the largest, continuous areas to be mapped using geophysical data ever attempted. The aim of this extensive project is to document evidence of human settlement in these hinterlands, prior to the flooding of this part of Europe.
Commenting upon this accolade, professor Gaffney modestly stated:
“It is both a surprise, and a great pleasure, to learn that I have been selected to receive an MBE for services to Archaeology. When receiving such an honour within Higher Education it is, of course, completely appropriate to recognise that an individual’s career is actually a result of the labours of numerous students, researchers and the many colleagues one works with over the years and I would like to think that I am accepting this honour for them all. It is also important to note the value of such awards to universities and their communities.”
Professor Gaffney added:
“Archaeology may be associated with Stonehenge and many glamorous monuments but to us, the archaeology of Bradford Park Avenue is equally important and our work there and elsewhere in Bradford and Yorkshire, links the University and the town and is the basis for future, globally important research.”
Some of the First Land Vertebrates Lived in Antarctica
The fossilised remains of two newly described Late Devonian tetrapods have helped to shed new light on the evolution of land vertebrates. Since most of the known Devonian tetrapod fossils are associated with equatorial palaeoenvironments, it had been thought that the first animals with back bones to adapt to a life on land must have lived in very close to the equator. However, these new specimens lived on the southernmost portion of the giant super-continent Gondwana. These early land pioneers of 360 million years ago were living within the Antarctic circle.

Devonian Tetrapods
The evolution of the first land animals from fish during the Devonian geological period is regarded as a key event in the history of life on Earth. Newly described fossils from the Waterloo Farm locality near Grahamstown (Easter Cape Province, South Africa), are challenging current perceptions about where in the world the first land vertebrates evolved.
Lead author of the scientific paper, published in the journal “Science”, Dr Robert Gess (Albany Museum, Grahamstown), explained:
“Whereas all previously found Devonian tetrapods came from localities which were in tropical regions during the Devonian, these specimens lived within the Antarctic circle.”
The First African Devonian Tetrapods
The researchers, including co-author Professor Per Ahlberg (Uppsala University, Sweden), name two new species Tutusius umlambo and Umzantsia amazana from fragmentary bones from a road cutting at the Waterloo Farm site, bones from the shoulder girdle related to these new early tetrapods, are helping palaeontologists to gain a better understanding of the development of the shoulder girdle from a fish to that of a tetrapod, adapted to walking around on land.
Tutusius and Umzantsia, are Africa’s earliest known four-legged vertebrates by a remarkable 70 million years. The approximately one-metre-long Tutusius umlambo (named in honour of Archbishop Emeritus Desmond Tutu) and the somewhat smaller Umzantsia amazana are both incomplete.
Tutusius is represented by a single bone from the shoulder girdle, whereas Umzantsia is known from a greater number of bones, but they both appear similar to previously known Devonian tetrapods. Alive, they would have resembled a cross between a salamander and a fish, with an amphibian-like head, stubby legs with numerous fingers and a tail that was reminiscent of a tadpole’s.

The Waterloo Farm site, where the fossils were discovered, is a road cutting first exposed two years ago after controlled rock-cutting explosions by the South African National Roads Agency (SANRAL). This very important fossil site is along the N2 highway between Grahamstown and the Fish River. The construction crew exposed dark, grey mudstones of the Witpoort Formation. The strata represent sedimentary deposits laid down in a brackish, tidal river estuary. The rocks preserve numerous fossils, including animals and plants.
The discovery of these fossils is extremely significant not only for what was found, but where they were found. Devonian tetrapod fossils are found in widely scattered localities. However, if the continents are mapped back to their Devonian positions, it emerges that all previous finds are from rocks deposited in the palaeotropics, between 30 degrees north and south of the equator.
Almost all these rare and important fossils come from Laurasia, a super-continent that later fragmented into North America, Europe and Greenland. Umzantsia and Tutusius have certainly bucked this trend. Gondwana, the much larger, southern super-continent (made up of present -day South America, Australia, Madagascar, Australia, India and Africa), has hitherto yielded virtually no evidence of Devonian tetrapods.
Footprints ascribed to early tetrapods have been discovered in Australia and an isolated jawbone was found in New South Wales. When this jawbone fossil was first studied, scientists thought it represented the jaw of a lobe-finned fish. However, subsequent research led to the conclusion that this single bone came from a primitive tetrapod. The species Metaxygnathus denticulus was erected.
During the later stages of the Devonian, this part of Australia was associated with the northern Gondwana. It would have been located in the tropics. As a result, it was assumed that movement of vertebrates from water onto land (terrestrialisation) also occurred in the tropics. Attempts to understand the causes of these major macroevolutionary steps therefore focused on conditions prevalent in tropical water bodies.

Challenging Current Perceptions and Assumptions About Tetrapod Evolution
The two early tetrapods named from Waterloo Farm fossils, also come from Gondwana, but from an environment associated with the southernmost part of the super-continent. Waterloo Farm was approximately seventy degrees south, within the Antarctic circle. Many plant and insect fossils recovered from the road side indicate that the climate was much milder than the Antarctic circle today, but it would still have been cold and during the long winter season, this region would have experienced many months when the sun did not appear above the horizon. These amphibians would have had to endure long periods of darkness.

The researchers conclude that these fossils change our understanding of the distribution of Devonian tetrapods. We now know that tetrapods occurred throughout the world by the Late Devonian and that their evolution and terrestrialisation could realistically have occurred anywhere.
Alberta Reveals New Driver’s Licence with Dinosaur Design
In a bid to help protect residents of the Canadian province of Alberta from counterfeiting and identify theft, driving licences have been redesigned and they will feature a skeleton of an Albertosaurus. This iconic, albeit somewhat extinct resident of southern Canada is honoured and the bones in the tail of the dinosaur image helps to improve the card’s security.
The New Driver’s Licence for the Canadian Province of Alberta

The provincial government has redesigned driver’s licences and identity cards with updated and improved security features such as clear windows, laser engraving and three-dimensional embossing. These features are designed to deter fraudsters and counterfeiters but the additional of an Albertosaurus skeleton must make this one of the coolest things that a wallet or purse could contain.
Stephanie McLean, (Minister of Service for Alberta) commented:
“Our government takes identity fraud very seriously. We are the first jurisdiction in North America to integrate this combination of design and security to protect Albertans from ID theft and prevent fraud. We are using the latest technology available to safeguard people’s personal information and prevent scams.”
Saving $1,000,000 Canadian Dollars
The new cards are currently in production and although the cards have a suite of security measures incorporated within them, advances in technology mean that they will cost less than the old licences to make. The Alberta treasury expects to save over $1,000,000 Canadian dollars as a result of the new design.
The driver’s licence design depicts famous landmarks such as Castle Mountain and the Bow River in Banff National Park, while the new identity cards will feature a Wild Rose, Alberta’s provincial flower. Both cards also include an image of an Albertosaurus, a dinosaur whose name honours Alberta.
Fossils of a very large predatory dinosaur had been uncovered in southern Canada prior to the turn of the Century and this dinosaur was finally named and scientifically described in 1905, the same year that the province of Alberta was established by an Act of Parliament. Coincidentally, 1905 was also the year that Tyrannosaurus rex, a famous relative of Albertosaurus was named.

Albertosaurus
The last redesign occurred nine years ago and the Alberta government has incorporated advice from law enforcement agencies to ensure the cards have the most up-to-date safeguards against fraudsters and identify thieves. The Albertosaurus image plays an important role in card security. The dinosaur’s image is embossed and has a raised feel to it. This creates a three-dimensional effect, the tail continues on the back of the card and appears to travel through the Alberta-shaped window, which also holds an image of the legitimate card holder.
A spokesperson from Everything Dinosaur commented:
“It is wonderful to see the authorities celebrating the natural beauty of the province of Alberta in such an interesting way. Having an iconic dinosaur on the driver’s licence will remind holders of the rich fossil heritage of this part of Canada.”

Scientists Discover Dinosaur Footprints in the Tatra Mountains
The beautiful and rugged Tatra mountain range forms a natural border between Poland and Slovakia, but during the Late Triassic, the sediments that formed part of these peaks were sandy shores close to large rivers where many different types of dinosaur wandered. Dinosaurs left their footprints in these soft sands, and remarkably some of these trace fossils have survived more than 200 million years and they are helping palaeontologists to better understand the composition of Late Triassic vertebrate faunas.
Media reports from the Centre of Interdisciplinary Biosciences of Pavol Jozef Šafárik University in Košice, Slovakia, confirm the discovery of yet more three-toed theropod dinosaur footprints, although most are badly eroded, these trace fossils indicate the presence of a sizeable predator, one that may have exceeded five metres in length.
The fossils come from the Tomanová Formation and although dating the strata is challenging, the rocks are thought to have been laid down during the Late Norian to the Rhaetian faunal stage of the Triassic (215 – 202 million years ago approximately).

Recording the Activity of Dinosaurs from the Late Triassic
The first dinosaur fossil footprints found in the High Tatras were described in 1976. These fossils and subsequent footprint discoveries led to the establishment of a new ichnospecies – Coelurosaurichnus tatricus. However, these new finds, ten dinosaur trace fossils, have helped shed further light on vertebrate fauna at an important time in our planet’s history. At around this time, a mass extinction event occurred and a number of terrestrial vertebrates (and other types of animal) became extinct, providing the Dinosauria with even greater opportunities to diversify and produce new species.
Commenting on these fossils, one of the palaeontologists who discovered them, Martin Kundrát (Centre of Interdisciplinary Biosciences of Pavol Jozef Šafárik University), stated:
“The locality is extremely rare for Slovak dinosaurology. It is located at high altitude. This does not mean, however, that dinosaurs have been hiking. The truth is that the sediments in which the traces were preserved were created hundreds of kilometres from Slovakia almost at the level of the then advancing sea. The layers of the tracks were later transported to the territory of Slovakia and raised to the stars. This is our modest dinosaur association. Two of them are complete, the rest are only fragments.”
One of the More Complete Footprint Fossils

Important Fossils Although Fragmentary Fossils
The fossil record for dinosaurs from Europe during the Late Triassic is relatively poor, so even these fragments are very helpful to palaeontologists as they attempt to piece together the biota of Pangaea. The trace fossils, although quite indistinct, help scientists to gain an understanding of the various types of dinosaur that roamed this part of the world more than 200 million years ago. Moreover, these new discoveries allow palaeontologists to revise their knowledge about an ancient ecosystem. Based on studies of similar imprints from South Korea, the United States, Iran and China, scientists have been able to make two important deductions.
First, the researchers have concluded that the former ichnotaxonomy (classification of an animal based on its footprints, burrows, or other traces) of Coelurosaurichnus tatricus is not valid.
Secondly, the number of imprints confined to a small area indicates that it was a very often frequented locality.
The Dinosaur Footprints Indicate a Theropod Around Five Metres in Length

In total, this part of the High Tatras has yielded several different types of dinosaur footprint. Several papers have been published previously describing ornithischian prints and the large, rounded tracks of what are assumed to be Sauropodomorpha, as well as numerous types of three-toed (tridactyl) prints assigned to the theropoda.
