Prehistoric Times Issue 136 Sneak Peek

The next cover of “Prehistoric Times”, the quarterly magazine for dinosaur fans and prehistoric animal model collectors, will feature a stunning illustration of the fearsome Deinonychus (D. antirrhopus).  This magnificent illustration of a deadly dromaeosaurid was created by the very talented Dutch artist Esther van Hulsen.

Esther does not focus solely on illustrating dinosaurs, although she has collaborated on a number of palaeontology projects.  She also illustrates living animals capturing their beauty in a variety of traditional media such as acrylics and water colours.

Inside issue 136, Esther discusses her work on a primitive primate.  The article will feature many more examples of her art.

John Lavas’s long-running biography of Zdenek Burian provides a segue linking one of the founding fathers of palaeoart to Esther, one of a new generation of exciting illustrators.  John Lavas focuses on Burian’s sauropods.

Phil Hore provides the low down on the low slung thyreophoran Sauropelta and tells the tale of the bizarre Longisquama (L. insignis) that was named and scientifically described fifty years ago.

Scottish scientist and science writer Dougal Dixon explains all about the dinosaur models he has created during lockdown and Canada is represented by palaeontologists Darren Tanke and Jordan Mallon who discuss the early illustrations of the eminent and highly influential Robert Bakker.

Randy Knol highlights spinosaurs and the various models that have been produced to represent this unusual family of theropods, whilst fellow American Tracy Ford digs into the dermal armour of Ankylosaurus, with lots of beautiful, armoured dinosaur illustrations too.

PNSO to Introduce New Version of T. rex “Wilson”

By | December 19th, 2020|Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|19 Comments

PNSO to Introduce New Version of T. rex “Wilson”

PNSO are going to introduce a new version of the Tyrannosaurus rex replica known as “Wilson”.  This beautifully crafted model, which is based on a real T. rex fossil specimen discovered by the famous American palaeontologist Barnum Brown, will be in stock at Everything Dinosaur in 2021.

The New PNSO “Wilson” the Tyrannosaurus rex Model

Based on AMNH-5027

The new Tyrannosaurus rex figure is based on the first, substantial skeleton of this iconic theropod dinosaur to be reconstructed and mounted for display.  The fossil specimen (AMNH-5027), consists of an almost complete skull (the first virtually complete T. rex skull to have been discovered), the pelvis, rib cage and a nearly complete vertebral column, including cervical vertebrae that proved that this dinosaur had a relatively short neck.  In total, about 45% of the skeleton was recovered and this famous fossil is on display at the American Museum of Natural History in New York.

The PNSO “Wilson” Figure is Based on an Actual T. rex Specimen

A Replica with a Deeper Chest

As this figure is based on fossil material the design team at PNSO have been very keen to get the body proportions correct.  The chest is much deeper and as a result, the arms look disproportionately much smaller.  The powerful and muscular legs that would have provided adequate support for the living animal are not quite up to the job when it comes to this new model.  In order to keep the feet anatomically correct, the model is supported by a transparent rod which helps to prop up the chest.

The model is supplied with a transparent support stand (PNSO T. rex).

A 1:35 Scale Model of Tyrannosaurus rex

The new PNSO “Wilson” the Tyrannosaurus rex measures around 34.5 cm long and it has a declared scale of 1:35.  The head stands 12.9 cm high and this beautifully designed dinosaur model is going to tick all the boxes for collectors who like their figures to represent real animals recorded in the fossil record.

Recognising the Importance of the Hell Creek Formation

With the introduction of “Sede” the Ankylosaurus, “Doyle” the Triceratops and “Wilson” the Tyrannosaurus rex, PNSO are recognising the significance of the famous Hell Creek Formation.  All three of these iconic dinosaurs have been reported from the Hell Creek Formation, although Ankylosaurus fossil material is exceptionally rare when compared to the Ceratopsidae and tyrannosaurids.

Schleich Brontosaurus Dinosaur Model in Stock

By | December 17th, 2020|Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|0 Comments

Schleich Brontosaurus Arrives at Everything Dinosaur

The last of the new for 2021 prehistoric animal models that have been recently announced by Schleich, the beautiful Brontosaurus dinosaur model, is now in stock at Everything Dinosaur.  Our shipment of Schleich Brontosaurus figures was separated from the other new figures that were scheduled to be delivered this week.  The Ceratosaurus, Pachycephalosaurus, Kaprosuchus and the marine reptile model Mosasaurus arrived yesterday, now the quintet of figures is complete with the delivery of the Brontosaurus.

Arrived Safely!  The New for 2021 Schleich Brontosaurus Dinosaur Model is Available from Everything Dinosaur

Bully for Brontosaurus

Brontosaurus is one of those dinosaurs that is popular and easily identified by the general public.  This is in part to it being featured in lots of films, television shows and books.  A Brontosaurus featured in the original King Kong movie that was distributed by Radio Pictures, released in 1933 and starring Fay Wray, Robert Armstrong, Bruce Cabot and of course, King Kong himself.  King Kong was a giant gorilla that shared its home (Skull Island), with a variety of dinosaurs including a fearsome, supposedly carnivorous Brontosaurus.

The genus name was erected by the eminent American palaeontologist Othniel Charles Marsh in 1879.  However, for many years it was regarded as a junior synonym of the closely related Apatosaurus that had been named earlier.  The name Brontosaurus was regarded as “nomen dubium”.

An extensive revision of the diplodocid dinosaurs, at the time the most comprehensive review of dinosaur fossil material ever undertaken (2015), led to establishment once again of Brontosaurus as a valid genus.

The scientific review of the Diplodocidae family of sauropods was undertaken by Dr. Emanuel Tschopp, Professor Octávio Mateus, (Museu da Lourinhã, Portugal), Dr. Roger Benson (Oxford University) and edited by Dr. Andrew Farke (Raymond M. Alf Museum of Palaeontology, California).  Schleich have added a replica of this famous Jurassic dinosaur to their range and it joins other long-necked dinosaur figures such as Barapasaurus, Brachiosaurus and the model of the South American sauropod Agustinia, which was only introduced a few months ago (2020).

One of our Dinosaurs is Missing!

A spokesperson from Everything Dinosaur commented:

“Just like in the 1975 Walt Disney production “One of our Dinosaurs is Missing”, Everything Dinosaur were missing a long-necked dinosaur.  Ports around the world have been very congested and delivery networks so stretched that sometimes cargoes are separated from each other, even though they are in the same shipment.  Within 24-hours all the Schleich figures were safely in our warehouse.”

New for 2021 Schleich Prehistoric Animal Models

The quartet of figures represent three prehistoric animals associated with the Cretaceous (Mosasaurus, Kaprosuchus and Pachycephalosaurus) and one theropod dinosaur from the Jurassic (Ceratosaurus).  Each model has been hand-painted and three of them have articulated jaws, the exception is the Pachycephalosaurus.  Model collectors like to know the measurements for any figures that Everything Dinosaur supplies.  With the Schleich range no scale for these models has been declared, but with an idea of the size of the actual figure, collectors can work out the scale themselves if they happen to know the approximate size of the animal, as calculated from the fossil record.

One Very Flashy New Dinosaur – Ubirajara jubatus

By | December 15th, 2020|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles, Photos/Pictures of Fossils|0 Comments

Ubirajara jubatus – One Very Flashy Dinosaur

News about the discovery of a species of feathered dinosaur has now become relatively commonplace.  Yet, it is worth remembering that it was just twenty-four years ago, back in 1996, that the first, non-avian dinosaur species with evidence of fuzzy feathers was described.  Named Sinosauropteryx this lithe meat-eater literally “rocked” scientists as the long-awaited proof of feathered dinosaurs was revealed to the world.  Sinosauropteryx was a compsognathid, a team of researchers, including scientists from the University of Portsmouth have described another feathered dinosaur, this new feathered theropod is a compsognathid too, but with a more elaborate and spectacular integumentary covering.  The newly described Ubirajara jubatus is the first Gondwanan non-avian theropod with preserved filamentous integumentary structures.  It is also the first non-maniraptoran possessing elaborate integumentary structures that were most likely used for display.

A Life Reconstruction of the Newly Described Brazilian Compsognathid Ubirajara jubatus

Dressed to Impress

Described as the most elaborately dressed-to-impress dinosaur described to date, the research team co-led by Professor David Martill and researcher Robert Smyth (University of Portsmouth), propose that U. jubatus will shed new light on how birds evolved elaborate display structures.

This chicken-sized dinosaur possessed a mane of long bristles running down its back and stiff ribbons projecting out and back from its shoulders, a combination of features never seen before in the fossil record.

The scientific paper has been published in the journal of Cretaceous research and involved a collaboration between the University of Portsmouth and the appropriately named Professor Dino Frey at the State Museum of Natural History, Karlsruhe, Germany, who discovered the new species while examining fossils in Karlsruhe´s collection and Héctor E. Rivera-Sylva of the Departamento de Paleontología, Museo del Desierto in Saltillo, Mexico.  The fossil was authorised by the Brazilian authorities for export some time ago, but was only recently studied.

The bizarre integumentary structures must have had a purpose, whilst the body covering may have originally evolved to provide insulation, the stiff ribbons on either side of the shoulders were probably used for display, perhaps to attract a mate, deter a rival or to frighten a potential predator.

Professor Martill commented:

“We cannot prove that the specimen is a male, but given the disparity between male and female birds, it appears likely the specimen was a male, and young, too, which is surprising given most complex display abilities are reserved for mature adult males.  Given its flamboyance, we can imagine that the dinosaur may have indulged in elaborate dancing to show off its display structures.”

Not Scales or Fur

The ribbons are not fur or scales, they are not feathers in the modern sense, as seen on an extant bird.  They appear to be structures unique to this animal.

Mr Smyth added:

“These are such extravagant features for such a small animal and not at all what we would predict if we only had the skeleton preserved.  Why adorn yourself in a way that makes you more obvious to both your prey and to potential predators?  The truth is that for many animals, evolutionary success is about more than just surviving, you also have to look good if you want to pass your genes on to the next generation.”

From the Lower Cretaceous (Aptian) Crato Formation of North-eastern Brazil

Fossil discoveries starting with the ground-breaking Sinosauropteryx specimen that was described in 1996 have fundamentally changed our understanding of the phylogenetic relationships between birds and dinosaurs as well as the origin and evolution of feathers.  A variety of elaborate integumentary coverings and structures are now known from the Theropoda and from ornithischian dinosaurs too.  They have been linked to behaviours including egg incubation, mating displays and thermoregulation.

Within the Theropoda, such features have only been previously recorded within the Maniraptoriformes, a theropod clade which includes birds and is defined as “the most recent common ancestor of the ostrich mimic Ornithomimus and Aves (birds) and all descendants of that common ancestor.”

The majority of theropods preserving integumental structures come from the Upper Jurassic and Lower Cretaceous of China or the Upper Jurassic of southern Germany and all are of Laurasian origin.  Ubirajara jubatus from the Lower Cretaceous (Aptian) Crato Formation of north-eastern Brazil, is the first non-maniraptoran possessing elaborate integumentary structures that were most likely used for display.

It is also the first non-avian theropod with preserved filamentous integumentary structures to have been described from the southern hemisphere landmass of Gondwana.

The researchers compare Ubirajara to living birds stating that many modern Aves are famed for their exotic and colourful plumage along with their complex displays that are used to win mates.  Male peacocks with their stunning tails and male birds of paradise are examples of this.

Ubirajara jubatus (pronounce You-bi-rah-jar-rah jew-bay-tus), lived approximately 110 million years ago (Aptian faunal stage of the Early Cretaceous).  The genus name is derived from the local Tupi dialect and translates as “lord of the spear”, whilst the trivial or specific name is from the Latin for “mane” a reference to the integumentary covering on its back.

Able to Raise its Hackles Like a Dog?

The mane running down its back is thought to have been controlled by muscles allowing it to be raised, in a similar way a dog raises its hackles or a porcupine raises its spines when facing a threat. Once the danger had passed, Ubirajara could lower its mane close to the skin allowing this little dinosaur to move quickly through the undergrowth without getting tangled up.

Professor Martill explained:

“Any creature with movable hair or feathers as a body coverage has a great advantage in streamlining the body contour for faster hunts or escapes but also to capture or release heat.”

The unique body plan of Ubirajara with its long, flat, stiff shoulder ribbons of keratin, each with a small sharp ridge running along the middle, described by the authors as “enigmatic” might have looked cumbersome, but in reality they were located on the body in such a way as not to impede movement allowing Ubirajara to preen, hunt, move around and display unencumbered.

Revising the Mamenchisauridae – Analong chuanjieensis

By | December 14th, 2020|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

Revising the Mamenchisauridae – Analong chuanjieensis

2020 has proved to be an important year for that enigmatic family of sauropods the Mamenchisauridae, which are predominantly associated with the Early Jurassic of China, although, as with most things relating to vertebrate palaeontology, there are exceptions to the consensus.  For example, the Late Jurassic Tanzanian genus Wamweracaudia is regarded by many scientists as a mamenchisaurid, based on the shape and structure of its tail bones (caudal vertebrae).

That’s the point with the mamenchisaurids.  They are one of the most extensively researched of all the Sauropodomorpha, thanks almost entirely to the numerous fossil bones found near Zigong in the Chinese Province of Sichuan.  However, even the most well-researched group of dinosaurs are subject to revision.

This is the case with a specimen of Chuanjiesaurus (C. anaensis) which is pronounced Chu-an-je-sore-us, a twenty-five metre long giant known from the Middle Jurassic Chuanjie Formation of Yunnan Province located in south-western China.

Chuanjiesaurus was named and described in 2000, from fossils found near to the town of Chuanjie in Lufeng County (Yunnan Province).  Intriguingly, a recent assessment of the disarticulated sauropod fossil remains found just a few metres away in the same quarry have demonstrated that these fossils are not the remains of a second Chuanjiesaurus as previously thought.

A Life Reconstruction of the Newly Described Mamenchisaurid Analong chuanjieensis

Analong chuanjieensis life reconstruction.

A life reconstruction of the recently erected mamenchisaurid taxon Analong chuanjieensis.  Fossils of this dinosaur, once regarded as a specimen of the related Chuanjiesaurus come from the Chuanjie Formation (Bajocian faunal stage of the Middle Jurassic).  Analong roamed China around 170-168 million years ago.

Picture Credit: Everything Dinosaur

In a scientific paper published in the International Journal of Paleobiology, Ren at al erected a new mamenchisaurid taxon based on a revision of specimen number LFGT LCD 9701-1.  Analong chuanjieensis is based on several autapomorphies (unique characteristics).  This reassessment has important implications for the Mamenchisauridae as a whole.  Analysis of the bones of the newly described Analong with other related mamenchisaurids indicate that Analong chuanjieensis is the earliest branching of the Mamenchisauridae family, whereas the contemporary Chuanjiesaurus represents a later branching of these types of dinosaurs.

In Recognition of the Increasing Public Awareness of the Mamenchisauridae CollectA are Introducing a Scale Replica of Mamenchisaurus in 2021

Thus, the establishment of a the new Analong taxon not only increases the number of long-necked dinosaurs known from the Middle Jurassic of China but also suggests that the ecosystem which was dominated by these herbivores was more complex and nuanced.  Furthermore, this reassessment of the fossil material suggests that the evolution of the Mamenchisauridae is more convoluted than previously realised.

For a related article on Chinese mamenchisaurs: Another Mamenchisaurid from Anhui Province – Anhuilong diboensis is described.

This large crested tapejarid, fossils of which herald from southern Brazil, was formally described back in 2014 (P. Manzig et al).  To read an article about the discovery of Caiuajara: New Species of Flying Reptile Identified from Pterosaur Graveyard.

Although the dating of the strata in which the pterosaur fossils were found has proved controversial, several palaeontologists estimate that this flying reptile with its 2-3 metre wingspan was flying over southern Brazil between 93 to 75 million years ago (Turonian to Campanian faunal stages of the Cretaceous).

Leaving feedback on the CollectA Deluxe Caiuajara figure on Everything Dinosaur’s website, Elizabeth commented:

“The CollectA Supreme line is a dream for lovers of pterosaurs.  I have leapt to buy each one!  This is a particularly striking creature with its massive crest.  I like the way that CollectA chose to paint it brightly to indicate a display feature to other Caiuajara.  The model is large and well made – an asset to any collection.”

Niebla antiqua

A New Medium-sized Abelisaurid – Niebla antiqua

A new species of Late Cretaceous abelisaurid theropod has been named based on fragmentary fossils found in northern Patagonia (Argentina).  The dinosaur has been named Niebla antiqua and it represents one of the most derived of all the abelisaurids described to date.  With an estimated body length of around 4 to 4.5 metres, Niebla is smaller than the roughly contemporaneous abelisaurid Quilmesaurus (Q. curriei), known from the same formation and considerably smaller than Carnotaurus sastrei.

Described recently in a scientific paper published in the Journal of South American Earth Sciences, the description being based on ribs, weathered vertebrae, a near complete braincase, lower jaw fragments (dentary) and teeth plus a relatively intact scapulocoracoid (pectoral girdle), Niebla helps to strengthen the fossil record of abelisaurids known from the Maastrichtian.

The fossil material was found during excavation of exposed Allen Formation strata located near Matadero Hill in the province of Río Negro by CONICET researchers.  Their study suggests that abelisaurid evolution may be more complex than previously thought.

Adding to the Diversity of South American Members of the Abelisauridae

Abelisauridae dinosaurs are very well known from South America.  However, the fossil record of the very youngest members of this theropod family (abelisaurids associated with the Maastrichtian faunal stage of the Late Cretaceous), is relatively poor.  The researchers describe a new species (Niebla antiqua), although the fossils are highly fragmentary, they conclude that the material represents an adult animal and therefore this dinosaur was a medium-sized abelisaurid, much smaller than other coeval abelisaurids such as Carnotaurus and Abelisaurus.

The genus name is from the Spanish for “mist” a reference to the foggy conditions that the field team encountered when conducting the excavation, whilst the trivial or specific name refers to the great age of the strata.

The braincase shows autapomorphic features (unique characteristics), such as a dorsoventrally tall basal tuber and postemporal foramen enclosed by parietal and exoccipitals.  The scapulocoracoid is notably similar to that of Carnotaurus (C. sastrei), the research team note a number of features including having a posterodorsally oriented glenoid, a dorsoventrally expanded and wide coraco-scapular plate and the blade of the scapula is very narrow and straight.  These anatomical traits are very different from those of other abelisaurids.  This might indicate a unique conformation of the pectoral girdle among these South American members of the Theropoda.
