A Velociraptor Illustration by PNSO

We wanted to post up another beautiful dinosaur illustration by the talented Chinese palaeoartist Zhao Chuang (Peking Natural Sciences Organisation).  So, without further ado, here is a beautiful drawing of the head and neck of a Velociraptor.

A Pictorial Guide to Palaeontology

Taken from “A Pictorial Guide to Palaeontology” by Zhao Chuang and Yang Ying, this Velociraptor illustration is devoid of feathers.  However, although Velociraptor may have been feathered, the head and neck could have been bare.  Some members of the vulture family, including species from the Old World as well as the Americas, lack feathers on the neck and head.  This allows them to feed on the carcasses of other animals without getting their feathers caked in blood.  In addition, the bare head and neck play a role in thermoregulation.  Lack of insulating feathers around the skull and neck, permit these large birds to lose heat to their surroundings, helping them to keep cool.

The bare-necked Velociraptor illustrated by Zhao Chuang may reflect similar themes, related to avoiding getting dirty feathers whilst feeding and thermoregulation.

Estemmenosuchus Scale Drawing

Estemmenosuchus Scale Drawing

One of the new 1:20 scale figures from CollectA for 2018 is a model of the Dinocephalian Estemmenosuchus.  We are not expecting this model to arrive in stock until the middle of this year, but we are busy preparing a fact sheet to accompany sales of this Permian herbivore (most scientists state that these animals were plant-eaters).  For virtually every named prehistoric animal model we sell, we include a fact sheet about that animal in with the customer’s order.  Along with the fact sheet, we also provide a handy scale drawing so that readers can see at a glance just how big this prehistoric animal was.

Deciding on Which Species of Estemmenosuchus to Depict

There are currently two species of Estemmenosuchus recognised, Estemmenosuchus mirabilis and the much larger Estemmenosuchus uralensis, but which species does the CollectA Deluxe 1:20 scale figure represent?  The CollectA model is over seventeen centimetres long and at 1:20 scale this represents an animal around 3.5 metres long.  This suggests that the model is getting towards the larger E. uralensis, which measured between 3.5 and 4.5 metres in length.  However, the larger Estemmenosuchus uralensis only had one pair of horny projections on the skull, whilst the smaller of the two recognised species E. mirabilis, had two pairs of horns on the top of the skull.

The CollectA Deluxe Estemmenosuchus Model (New for 2018)

There are other anatomical differences too.  The skull of the larger species Estemmenosuchus uralensis was up to fifty percent longer.  The muzzle of E. mirabilis is proportionately smaller, but wider towards the front (anterior portion), there are also subtle differences in the morphology of the skulls, although both species show the characteristic thickened bone which is so reminiscent of the estemmenosuchids.  Based on this information, we think that the new for 2018 CollectA Deluxe Estemmenosuchus represents the smaller of the two valid species (E. mirabilis).  Our scale drawing has therefore been prepared based on an animal measuring around three metres in length and weighing an estimated 750 kilograms.

Updating Dromaeosaurids

Updating Dromaeosaurid Illustrations

Time to update and re-evaluate some of the scale drawings and details within Everything Dinosaur’s range of fact sheets.  The UK-based company has produced hundreds of dinosaur and prehistoric animal data sheets and from time to time, the information and illustrations needs to be updated.  Over the next few weeks our team members will be concentrating on changing some of the information associated with our Theropod fact sheets, specifically those associated with Maniraptorans.

Maniraptoran Dinosaurs Defined

The Maniraptora is a clade of Theropod dinosaurs consisting of those Coelurosaurian dinosaurs that are closely related to birds (Aves).  It includes the birds and the non-avian dinosaurs that were more closely related to them than to ornithomimids specifically, the type species Ornithomimus velox.  The Theropod dinosaurs that are more closely related to birds are classified into a sub-clade Eumaniraptora.  The Eumaniraptora (it means the “true maniraptorans”), consists of all the types of dinosaur more closely related to birds than to the Oviraptorosaurs.  The term Eumaniraptora is often replaced by the term Paraves, although palaeontologists do differ in their views as to the exact composition of Eumaniraptora and Paraves.  Essentially, a dinosaur such as the sickle-toed-clawed Deinonychus (illustrated above), as a member of the Dromaeosauridae family, along with the troodontids and the true birds (Avialae), are components of this sub-clade.

Dromaeosaurid Drawing

As Everything Dinosaur prepares for the introduction of the Beasts of the Mesozoic 1:6 scale range of model raptors, we are busy compiling fact sheets on all the new figures.  A series of dromaeosaurid and related Maniraptora drawings have been commissioned.  These illustrations will be used to show the approximate size of each of the prehistoric animals represented by a Beasts of the Mesozoic figure.

Feathered Friends

We aim to have all the fact sheets finished by the middle of January, in plenty of time for the launch of this range.  The above illustration shows the typical bauplan of a dromaeosaurid, note the addition of a feathery coat and a large fan of feathers on the end of the long tail.  The family Dromaeosauridae is very diverse, geographically widespread and with a wide temporal range.  The term “Dromaeosaur” means “running lizard”, all the dromaeosaurids were bipedal and in all likelihood, fast runners.

Distantly related to modern birds, we shall try not to get in a flap as we compile the dozen or so fact sheets that we need.

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 but instead their digging uncovered the substantial tusks of a long-extinct member of the elephant family.

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.

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).

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.

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.

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.

The diversity of the feathered Theropods is beautifully illustrated by this wonderful image created by Jan Sovak.

This 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.

Our dedicated team members compiled the information required by our emailer and duly sent it off, along with some links to other articles written by Everything Dinosaur staff that illustrate some of the huge variety of different dinosaurs we listed.

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 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).

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.

Basilosaurus Illustrated

By | August 14th, 2017|Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Main Page|0 Comments

A Drawing of the Early Predatory Whale Basilosaurus

Basilosaurus was one of the first, large whales to evolve.  This animal named “regal reptile”, the first species of which was named and described by Richard Owen (Basilosaurus cetoides), in 1839, has grown in popularity amongst fans of prehistoric animals.  Basilosaurus appeared in an episode of the “Walking with Beasts” television series made by the BBC, (episode two “Whale Killer”).  With CollectA recently introducing a replica of this placental mammal, collectors have the opportunity to add an early cetacean to their model collection.   Everything Dinosaur has commissioned drawings of Basilosaurus.  In the light of the adding of the PNSO range of models to Everything Dinosaur’s huge product portfolio, we have posted up a PNSO inspired Basilosaurus drawing, one that has not been published on this blog that often.

Although this fearsome carnivore, superficially resembled the toothed whales that are around today.  Basilosaurus was an evolutionary dead end, when Basilosaurus became extinct some 36 million years ago, towards the end of the Eocene Epoch, it left no descendants.  The drawing above is based on the PNSO Age of Dinosaurs Basilosaurus replica.

A Scale Drawing of the Spinosaurid Suchomimus

By | July 31st, 2017|Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Main Page|0 Comments

Suchomimus Scale Drawing

Suchomimus (S. tenerensis) fossils were first found in 1973, but at the time, little was known about spinosaurids.  Recent reviews of the fossil material have placed this dinosaur from the Early Cretaceous of Niger within the Spinosauridae, specifically assigned to the Baryonychidae.  Some studies (2002), concluded that the fossil material represented a second species of Baryonyx and proposed the name Baryonyx tenerensis.  Subsequent research established a number of autapomorphies (distinctive features), between the fossils assigned to Baryonyx and Suchomimus, enabling the two genera to be retained.  Suchomimus was probably very closely related to Baryonyx walkeri.

A Scale Drawing of Suchomimus (S. tenerensis)

The hosting rock has been dated to the Late Aptian faunal stage, suggesting that Suchomimus lived many millions of years after Baryonyx.  Like Baryonyx, the first fossil material found was an enlarged thumb claw.  The holotype fossil material of Suchomimus is much bigger than the holotype fossil material of Baryonyx (B. walkeri).  However, as the ages of the individual dinosaurs are not known, direct size comparisons are not relevant.  Based on the Suchomimus material (and that previously assigned to Cristatusaurus lapparenti), Suchomimus could have exceeded eleven metres in length and weighed as much as four tonnes.

Suchomimus translates as “crocodile mimic”, a reference to the long, crocodile-like snout, lined with conical teeth adapted for grasping slippery prey such as fish.
