“Prehistoric Times” Magazine

The spring issue (149) will feature an in-depth interview with palaeontologist Jordan Mallon. Dr Mallon is based at the Canadian Museum of Nature (Ottawa, Canada). He specialises in studying dinosaur ecology and has been involved in the naming and scientific description of several fossil species, including a horned dinosaur – Spiclypeus shipporum. Although both members of the Ceratopsia clade and contemporary, Styracosaurus and Spiclypeus were not closely related. The centrosaurine Styracosaurus albertensis is known from the Dinosaur Provincial Park Formation of Alberta, (Canada). In contrast, the chasmosaurine Spiclypeus shipporum is known from the Judith River Formation of Montana (United States).

The Pterosaur Tapejara

The other prehistoric animal to be featured in the spring edition is the pterosaur Tapejara. Readers can expect a comprehensive profile of this Early Cretaceous flying reptile. Tapejara is famed for its huge head crest. We are looking forward to viewing all the reader submitted artwork illustrating this spectacular member of the Pterosauria.

In addition, details will be provided of new books chronicling the life and work of the influential Czech artist Zdeněk Burian. Issue 149 will also feature the latest instalment of the excellent series penned by Jon Lavas discussing the artwork of Burian.  Jon contacted us to let us know that the next instalment covers South American ungulates but Burian did not actually do any formal paintings of these. Instead, Jon has used some of his own illustrations for the article. However, Burian’s artwork will continue in issue 150.

The work of English palaeoartist Bob Nicholls is also featured. Bob illustrated the wonderful “Dinosaur Behavior” which was launched late last year. This excellent dinosaur book was written by Professor Mike Benton (University of Bristol). Published by Princeton University Press “Dinosaur Behavior” is a beautifully illustrated and highly informative guide to the Dinosauria.

The eight main stamps feature beautiful illustrations of prehistoric animals by the Exeter-based digital concept illustrator Joshua Dunlop. Six dinosaurs are featured along with a pterosaur (Coloborhynchus) and a plesiosaur (Cryptoclidus). Picture credit: Royal Mail.

Celebrating Two Hundred Years Since the Formal Description of Megalosaurus

2024 marks the two hundredth anniversary of the formal, scientific description of a prehistoric animal that was later to be classified as a dinosaur. The theropod dinosaur Megalosaurus was named and described in 1824 by the Reverend William Buckland who was president of the Geological Society of London. The binomial species name Megalosaurus bucklandii was erected in 1827. This was the first scientific account in the western world of a dinosaur. Megalosaurus features on a pair of stamps along with the roughly contemporaneous marine reptile Cryptoclidus.

Megalosaurus was for a long time a taxonomic waste basket. Theropod fossils from different strata were assigned to this taxon. The only definitive Megalosaurus remains come from Oxfordshire (England).

Royal Mail Prehistoric Animal Stamps

The eight prehistoric animal stamps were created by Joshua Dunlop, a digital concept artist based in Exeter (Devon). A second set of stamps features a portrait of the pioneering fossil collector Mary Anning. In addition, three stamps have been created that show photographs of fossils associated with Mary Anning and the Lower Jurassic rocks of Lyme Regis.

The list of dinosaurs featured:

  • Tyrannosaurus
  • Triceratops
  • Stegosaurus
  • Diplodocus
  • Iguanodon
  • Megalosaurus

North American dinosaurs are featured (Tyrannosaurus, Triceratops, Stegosaurus and Diplodocus). Prehistoric animals known from fossil discoveries from southern England are also included. Each pair of stamps show a similar image but from a different prehistoric animal’s perspective. For example, one pair of stamps depicts a herd of Iguanodon escaping a forest fire whilst a flock of startled pterosaurs (Coloborhynchus) fly overhead.

Everything Dinosaur Comments

A spokesperson from Everything Dinosaur commented:

“These are beautiful stamps. The eight prehistoric animal stamps show four different scenes, and they are designed to be viewed as pairs. For instance, the Tyrannosaurus stamp shows this theropod attacking a Triceratops. In contrast, the Triceratops stamp shows the horned dinosaur fending off a lunge from the Tyrannosaurus.”

New “Prehistoric Times” Issue 148 Reviewed

By |2024-05-09T08:58:53+01:00February 28th, 2024|Adobe CS5, Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Magazine Reviews, Main Page, Prehistoric Times|0 Comments

Issue 148 of “Prehistoric Times” magazine is jam-packed with interesting articles, amazing drawings and fascinating features.  Fans of human evolution are treated to a personal tour of some of the exhibits on display at the Neanderthal Museum in Mettmann (North Rhine-Westphalia, Germany).  Our guide Dr Andreas Forrer visits the site where the first Homo neanderthalensis bones were found in 1856. Dr Forrer brings us up to date on genetic research that might lead to the generation of Neanderthal tissue in a laboratory.  These cells would be used to research into the development of the human immune system.

The front cover artwork for issue 148 was supplied by Jaime Chirinos.  A herd of titanosaurs (Saltasaurus australis) is being pursued by a pack of abelisaurids (Quilmesaurus curriei).  It is a most dramatic prehistoric scene.  The complete illustration can be found inside the magazine along with another stunning piece of art from Jaime Chirinos depicting Carcharodontosaurus feeding.

Zdeněk Burian and Sparassodonts

Jon Lavas continues his series highlighting the contribution to palaeoart made by Zdeněk Burian.  Prehistoric mammals have been the focus of recent articles and in issue 148 he looks at the enigmatic Sparassodonts, (Sparassodonta).  These carnivorous mammals were related to marsupials and as Lavas points out, they are not often featured in prehistoric art.  On the subject of art, famous palaeoartist Jon Sibbick wrote to the magazine editor confirming that after a long and illustrious career, he would not be undertaking any more commercial projects.

There is a lot of reader submitted artwork throughout the magazine including some delightful illustrations of prehistoric animals from Asbury Park High School pupils.  The photograph of the artwork laid out on the floor reminded us of the many hundreds of dinosaur illustrations we received when Everything Dinosaur team members worked in schools.

Ambulocetus and Australovenator

Phil Hore provides the text for the articles on the two featured prehistoric animals Ambulocetus and Australovenator.  There are some marvellous reader submitted artwork on the ancestor of whales.  Congratulations to Anders Bang, Giovanni De Benedictis and Nick Papadimitriou. Tim Bollinger provides an Australovenator in lateral view, whilst Ethan Martinicky illustrates a pair in the rain with a pterosaur in close attendance.   Kevin Hedgpeth chose to draw an Australovenator skull, and it is a splendid illustration.

Tracy Lee Ford continues his series looking at the skin of sauropods and regular contributor Randy Knol looks at models of prehistoric animals from the Permian and highlights some of the smaller figures from PNSO.  He also discusses marine reptile figures with a focus on some CollectA marine reptiles.  Editor Mike Fredericks brings us news of new CollectA and Safari model releases including the Wild Safari Prehistoric World Utahraptor that recently arrived at Everything Dinosaur.

The sad passing of Dr Martin G. Lockley is noted, and our sympathies go out to his colleagues, family and friends.

I Found a Dinosaur Egg

Kenneth Carpenter (University of Colorado Museum of Natural History) provides an identification guide to dinosaur eggs.  He comments upon the numerous times he has been presented with an abraded pebble by a member of the public who is convinced that they have found a dinosaur egg.

This happens to Everything Dinosaur team members too.  We get sent images of all kinds of rounded objects and we patiently explain that this is a concretion, a nodule or something similar.  We do our best not to disappoint the finder and for fans of prehistoric animals you will not be disappointed with the extensive “Paleonews” section in the magazine.  Recent news stories about dinosaurs living in burrows, mosasaurs from Morocco and megaraptorids from Australia are covered.  The huge Dorset pliosaur skull that was the subject of a recent television documentary narrated by Sir David Attenborough is also featured.

Take a look at the article on the Naturalis Biodiversity Center (Leiden, Netherlands) by Paul McFarland.  There are some fabulous photographs of prehistoric animal skeletons on display.

Thanks to artist Fabio Pastori for his wonderful illustrations.  It was also a treat to view some more artwork from Ely Kish included in the magazine.

Our congratulations to all involved in “Prehistoric Times” magazine issue 148.  As always, this quarterly magazine is crammed full of amazing artwork and fascinating features.

Creating a New Tlatolophus Scale Drawing

By |2024-03-17T09:28:37+00:00February 26th, 2024|Adobe CS5, Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Press Releases|0 Comments

Everything Dinosaur has commissioned a Tlatolophus galorum scale drawing. It will be used on a fact sheet being created that will be sent out with sales of Tlatolophus models. The fact sheet is being prepared as the Haolonggood Tlatolophus figures are due to arrive soon.

Tlatolophus galorum

A beautifully preserved and semi-articulated hadrosaur tail was excavated from Campanian-aged deposits of the Cerro del Pueblo Formation (Coahuila, Mexico). Fieldwork revealed extensive fossil material and this duck-billed dinosaur was formally named and described in 2021 (Ramírez-Velasco et al).

What’s in a Name?

The genus name Tlatolophus is pronounced Tlat-to-lo-fus.

This name is derived from a local dialect (Náhuatl), and it translates as “word”. In addition, the genus name uses the Greek lophos “crest”. The etymology relates to this dinosaur’s head crest being similar to a symbol in the Aztec culture resembling an inverse comma that means “word”.

The species or trivial name honours the philanthropist Jesús Garza Arocha and recognises the assistance of the López family, who helped the palaeontologists by providing food and accommodation during the field seasons.

A spokesperson from Everything Dinosaur commented:

“We will complete the Tlatolophus galorum fact sheet shortly. It will be ready for the arrival of the Haolonggood figures which are expected in about twenty days or so.”

Getting to Grips with the Enigmatic Caenagnathidae

By |2024-02-07T10:13:48+00:00February 10th, 2024|Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Main Page, Palaeontological articles, Photos of Everything Dinosaur Products, Photos/Pictures of Fossils|0 Comments

With the publication of the scientific paper announcing the discovery of Eoneophron infernalis, we at Everything Dinosaur thought we would take a closer look at the Caenagnathidae. The Caenagnathidae family (pronounced seen-nag-nay-thid-ay), are part of the Oviraptorosauria clade of maniraptoran theropod dinosaurs. They are closely related to the oviraptorids (Oviraptoridae family).

Defining the Maniraptora and the Oviraptorosauria

The Maniraptora clade consists of coelurosaurian dinosaurs and is defined as including the birds and the non-avian dinosaurs more closely related to them than to Ornithomimus velox. As well as containing the Oviraptorosauria, this clade also includes several other groups such as the dromaeosaurids, the Troodontidae family and the therizinosaurs.

The Oviraptorosauria clade* is comprised of the Caudipteridae family and two closely related dinosaur families the Caenagnathidae and the Oviraptoridae that together are classified as the Caenagnathoidea. The Oviraptorosauria are united by having very bird-like skeletons, with highly pneumatised bones. In addition, the rostrum is very short, and these dinosaurs have beaks. The beak is often, but not always edentulous (no teeth). These dinosaurs were all probably feathered.

The Caenagnathidae Family and Eoneophron infernalis

The family Caenagnathidae, together with its closely related sister family the Oviraptoridae, comprises the superfamily Caenagnathoidea. Virtually all known members of this superfamily are confined to the Late Cretaceous. Taxonomically the Caenagnathidae is defined as Chirostenotes pergracilis and all other theropods more closely related to it than they are to Oviraptor philoceratops.

Most of these dinosaurs tend to be quite small. As a result, they are probably underrepresented in the fossil record. For example, Anzu wyliei was thought until recently to be the only caenagnathid from the Hell Creek Formation. However, there are probably at least three caenagnathids present in Hell Creek strata, including the recently named Eoneophron infernalis.

Caenagnathids Not Closely Related to Ostriches

The Caenagnathidae family was originally erected by Raymond Martin Sternberg (1940), the son of the pioneering palaeontologist Charles Mortram Sternberg. Raymond Martin Sternberg thought that these dinosaurs were flightless birds. He erected the Caenagnathidae family which translates as “recent jaws”. It was mistakenly thought that these theropods were closely related to the Palaeognathae “old jaws” bird family. Extant palaeognath birds include the flightless Kiwi, the Ostrich and the Rhea as well as volant forms such as Tinamou birds. It is now known that the Caenagnathidae family of non-avian dinosaurs are not closely related to palaeognaths.

Caenagnathids are confined to the Late Cretaceous of Asia and North America. They tend to have small heads, long necks and short tails.

Challenging Phylogenetic Assessment

Whilst the fragmentary nature of most caenagnathid specimens makes phylogenetic assessment challenging, in the recent Eoneophron infernalis paper the researchers undertook a time-calibrated phylogenetic analysis of the Oviraptorosauria. Eoneophron was placed as a sister taxon to Citipes elegans and Elmisaurus rarus.

The difficulties involved in classifying oviraptorosaurs is exemplified by this placement. Although skeletal similarities between these three dinosaurs exist, there is a lack of comparable fossil material to study. Citipes elegans is geologically older. Its fossils come from the Dinosaur Provincial Park Formation of Alberta (Campanian faunal stage of the Late Cretaceous). In contrast, Elmisaurus rarus probably predates Eoneophron infernalis by a couple of million years. It too is from the Maastrichtian faunal stage of the Cretaceous. However, E. rarus fossils come from the Nemegt Formation of Mongolia.

A revision of already described specimens coupled with improved fossil sampling should help palaeontologists to gain a better understanding of the taxonomy of the Oviraptorosauria and specifically the enigmatic Caenagnathidae.

The Oviraptorosauria clade* also includes some other theropods regarded as basal members of this clade. For example, Incisivosaurus gauthieri from the Early Cretaceous of China.

Carnotaurus sastrei

This large theropod was named and described in 1985 by José Fernando Bonaparte. Bonaparte was an extremely influential figure in the development of palaeontology in South America. He is responsible for the scientific description of numerous dinosaurs from Patagonia, and he inspired a new generation of Argentinian palaeontologists.

The Carnotaurus illustration was inspired by the CollectA Deluxe 1:40 scale Carnotaurus sastrei figure. This popular dinosaur model was introduced in 2019.

Everything Dinosaur Fact Sheets

A spokesperson for Everything Dinosaur explained that for the vast majority of models and figures that the company supplies a free fact sheet about that prehistoric animal is sent out. Hundreds of fact sheets have been researched and written.

The spokesperson added:

“We continue to add to our free fact sheet inventory. The last two new fact sheets we introduced were for the tyrannosaur Alectrosaurus and the South American theropod Megaraptor namunhuaiquii. We commission illustrations of prehistoric animals such as Carnotaurus and this drawing will be used to update the scale drawing on our Carnotaurus fact sheet.”

The prehistoric elephant is shown in lateral view as it moves through a woodland in North America during the Pleistocene Epoch. James has chosen to depict a mature animal given the impressive size of the tusks on this prehistoric elephant.

Columbian Mammoth Artwork

The Columbian mammoth (Mammuthus columbi) was among the last mammoth species to evolve. It was also one of the largest with some fossil specimens indicating mature bulls some 4.2 metres high at the shoulders. Body weights of the biggest individuals have been estimated at more than twelve tonnes. The last of these amazing creatures are thought to have become extinct around 12,000 years ago.

A spokesperson from Everything Dinosaur thanked James for sending in the image of his Columbian mammoth artwork and exclaimed:

“We do get sent drawings and paintings of Woolly Mammoths, but we don’t receive many illustrations of Columbian mammoths. Our thanks to James for sending in an image of his superb artwork”.

Student Discovers Remarkable Late Triassic Flying Reptile in Somerset

By |2024-01-23T09:12:59+00:00January 22nd, 2024|Adobe CS5, Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Main Page, Palaeontological articles, Photos/Pictures of Fossils|0 Comments

A student from the University of Bristol has confirmed the presence of Kuehneosaurs in the Late Triassic of southwestern England. These gliding reptiles were part of a rich reptile dominated fauna that lived on a series of sub-tropical islands, part of an ancient archipelago. The biggest island extended from Frome in the east to Weston-super-Mare in the west. It was around eighteen miles (thirty kilometres long). It is referred to as the Mendip Palaeo-island.

Kuehneosaurs on Sub-tropical Islands

Kuehneosaurs superficially resemble lizards. However, they were more closely related to the ancestors of crocodilians and dinosaurs. They were small animals, which could fit neatly on the palm of a hand, and there were two species present. One species had extensive wing flaps, the second species had much shorter wings. These wings consisted of skin stretched over elongated ribs. Powered flight was beyond them, but they probably were very competent gliders.

Kuehneosaurs probably occupied a niche in the ecosystem similar to the extant flying lizard Draco from southeast Asia. They most likely wandered about on the ground and climbed trees in search of insects and other small invertebrates. To escape from predators, or to make rapid progress through the trees, they could launch themselves into the air and glide for several metres.

The discovery of Kuehneosaurs in the Late Triassic ecosystem was made by University of Bristol Masters student Mike Cawthorne. He had been examining numerous reptile fossils collected from limestone quarries, which represent deposits associated with the Mendip Palaeo-island.

No Dinosaur Fossils Found but They Were Probably Present

The research, published in the “Proceedings of the Geologists’ Association”, also records the presence of reptiles with complex teeth, the trilophosaur Variodens and the aquatic Pachystropheus that probably lived a bit like a modern-day otter likely eating shrimps and small fish. However, no dinosaur bones were found. These animals either fell or their bones were washed into caves and cracks in the limestone. This led to their preservation and the development of a fossil assemblage.

Masters student Mike Cawthorne commented:

“All the beasts were small. I had hoped to find some dinosaur bones, or even their isolated teeth, but in fact I found everything else but dinosaurs. The collections I studied had been made in the 1940s and 1950s when the quarries were still active, and palaeontologists were able to visit and see fresh rock faces and speak to the quarrymen.”

A Home for a Diverse Assemblage of Small Reptiles including Kuehneosaurs

Professor Mike Benton from Bristol University’s School of Earth Sciences added:

“It took a lot of work identifying the fossil bones, most of which were separate and not in a skeleton. However, we have a lot of comparative material, and Mike Cawthorne was able to compare the isolated jaws and other bones with more complete specimens from the other sites around Bristol. He has shown that the Mendip Palaeo-island, which extended from Frome in the east to Weston-super-Mare in the west, nearly 30 km long, was home to diverse small reptiles feeding on the plants and insects. He didn’t find any dinosaur bones, but it’s likely that they were there because we have found dinosaur bones in other locations of the same geological age around Bristol.”

Paying Tribute to the Fossil Collectors

Dr David Whiteside (University of Bristol) praised the work of the amateur fossil collectors and academics who found the fossils stating:

“The bones were collected by some great fossil finders in the 1940s and 1950s including Tom Fry, an amateur collector working for Bristol University and who generally cycled to the quarries and returned laden with heavy bags of rocks. The other collectors were the gifted researchers Walter Kühne, a German who was imprisoned in Great Britain in the second world war, and Pamela L. Robinson from University College London. They gave their specimens to the Natural History Museum in London and the Geological collections of the University of Bristol.”

Everything Dinosaur acknowledges the assistance of a media release from the University of Bristol in the compilation of this article.

Preparing for the New Beasts of the Mesozoic Figures (Alectrosaurus)

By |2024-01-22T09:30:56+00:00January 21st, 2024|Adobe CS5, Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Press Releases|0 Comments

Team members at Everything Dinosaur are busy preparing for the arrival of the new Beasts of the Mesozoic figures. They are wave three of the tyrannosaur series and the new figures will include the Asian tyrannosaur Alectrosaurus (Alectrosaurus olseni).

The new tyrannosaur figures include:

  • Eotyrannus lengi
  • Moros intrepidus
  • Albertosaurus sarcophagus
  • Gorgosaurus libratus
  • Daspletosaurus torosus
  • Tarbosaurus bataar
  • Alectrosaurus olseni

To view the range of Beasts of the Mesozoic models in stock: Beasts of the Mesozoic Models.

Alectrosaurus olseni

Alectrosaurus is known from hindlimb fossils and fragmentary elements of the hips. Much of the ascribed fossil material was discovered during the Third Asiatic Expedition to Inner Mongolia (China), by the American Museum of Natural History. It was formally described in 1933 (Gilmore).

The fossil material came from deposits associated with the Iren Dabasu Formation. The age of the strata remains uncertain. Relative dating using the abundant ostracod fossils suggest a Late Campanian to Maastrichtian age. However, the vertebrate assemblage represents fauna that indicate that the deposits are much older perhaps dating from the Turonian faunal stage. This would suggest that Alectrosaurus lived around 90 mya (million years ago).

The size of Alectrosaurus olseni is unknown. Its body length has been estimated at between five and six metres. Analysis of the limb bones and their ratios (femur to tibia), indicate that this dinosaur was a fast runner. It was probably a pursuit predator. The weight of A. olseni has been estimated to be around six hundred kilograms.

An Everything Dinosaur Scale Drawing

As part of our preparations for the arrival of the new Beasts of the Mesozoic tyrannosaurs, we have commissioned an Alectrosaurus scale drawing. This illustration will be incorporated into the free fact sheet that we will send out with the Alectrosaurus olseni model.

Ten years ago team members at Everything Dinosaur created a series of illustrations of prehistoric animals to help schoolchildren in a project. A total of twelve different drawings were produced illustrating life on Earth in prehistoric times. These drawings were then made into a calendar. The children could colour in or paint these illustrations to create their own unique prehistoric scene. The January 2014 artwork featured a Quetzalcoatlus drawing.

The Quetzalcoatlus Drawing

The huge Quetzalcoatlus is pictured flying over a dense conifer forest. Despite the emergence of angiosperms, conifers still made up a substantial proportion of the trees to be found on the landmass of Laramidia. These drawings were created to help the children with their Key Stage 2 term topic. The term topic focused on dinosaurs and fossils, however, giant pterosaurs featured too. The scheme of work also involved looking at the career of a famous palaeontologist and introduced the children to the work of Mary Anning.

The model (above) is a Quetzalcoatlus figure from the Wild Safari Prehistoric World range. It has been praised by collectors for providing an excellent representation of an azhdarchid pterosaur.

A spokesperson from Everything Dinosaur recalled the time and effort that went into the term topic and praised the teaching team for constructing such an innovative scheme of work for the children.
