Priced extremely competitively, dinosaur fans and discerning model collectors have the opportunity to acquire the W-Dragon range from a well-respected UK-based company with the ability to send parcels to a global customer base.

The Giganotosaurus (G. carolinii) dinosaur model is just the first of a series of figures that are being shipped by Everything Dinosaur.  The W-Dragon Giraffatitan figure is expected to follow in the New Year along with the W-Dragon Spinosaurus replica, a production run of which was especially commissioned by Everything Dinosaur.

A fact sheet on Giraffatitan is currently being prepared as team members await the arrival of the second shipment of W-Dragon models into their warehouse.

Developing Closer Links with Producers

Everything Dinosaur has been working closely with W-Dragon for some time helping this exciting model manufacturer by providing advice on product safety tests and certification, putting in place effective logistics to permit authorised movement of goods across international borders and ensuring a legitimate transfer of funds to secure products and support additional production runs.

Safely Arrived at Everything Dinosaur – The W-Dragon Giganotosaurus Dinosaur Model

Niebla antiqua

By | December 10th, 2020|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

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.

Thalassodraco etchesi – A New Species of Ichthyosaur is Described

By | December 9th, 2020|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

Thalassodraco etchesi – A New Species of Ichthyosaur is Described

A new kind of ichthyosaur has been named and described following the discovery of a partial, articulated skeleton preserved in a limestone concretion on the Dorset coast (southern England).   The fossil material consisting of the anterior portion of the marine reptile was discovered by renowned amateur fossil hunter Dr Steve Etches MBE, the founder of the Etches Collection museum, located on Kimmeridge Bay, not too far from where this new species was discovered.

This new species has been named Thalassodraco etchesi, the name translates as “Etches Sea Dragon”.

Unusual Dentition

Noticing the numerous, small teeth in the jaws, there are more than seventy teeth in the upper jaws alone, Steve passed his find onto researchers at the University of Portsmouth.  The scientific paper on the fifth known ichthyosaur from the Late Jurassic has been published in the on-line, open-access journal PLOS One.

Corresponding author of the paper, University of Portsmouth Masters student, Megan Jacobs, comments that at an estimated two metres in length, it is the smallest ichthyosaur from the Late Jurassic to be described to date.

The location of the fossil discovery – Kimmeridge Bay is part of the Jurassic Coast World Heritage Site.  The material comes from a limestone layer known as the White Stone Band.  When it died, the seafloor would have been a very soft ooze, allowing the front half of the animal to sink into the mud, before scavengers came along and ate the tail end.

As the anterior portion of the carcass was partially buried it was protected from being scavenged and the fine particles of mud which encased it provided conditions for exceptional preservation.  Stomach contents along with ligaments and some other soft tissues have been preserved.

Commenting on the specimen, Megan stated:

“Skeletons of Late Jurassic ichthyosaurs in the UK are extremely rare, so, after doing some research, comparing it with those known from other Late Jurassic deposits around the world, and not being able to find a match was very exciting.  Thalassodraco etchesi is a beautifully preserved ichthyosaur, with soft tissue preservation making it all the more interesting.  Steve’s incredible collection contains many new and exciting animals, and being given the chance to describe this ichthyosaur was a real privilege.”

A Deep Body but Small Forelimbs

The researchers noted the unusual body shape of the small ichthyosaur, it had a deep ribcage, small forelimbs and jaws lined with dozens of tiny, conical teeth.  It may have filled a slightly different niche in the Late Jurassic marine ecosystem compared to other ichthyosaurs.

Co-author of the paper, Professor David Martill, who leads the vertebrate palaeontology research unit at the University of Portsmouth commented:

“Steve is an exceptional fossil collector and although he is sometimes referred to as an amateur collector, he has done so much for palaeontology that he has been awarded an MBE, and is truly a pro.  If it were not for collectors like Steve, scientists would have very few specimens to work on.”

With the publication of the scientific paper formally naming this new species of marine reptile, the research does not end.  The team hope to study the specimen, which is part of the Etches Museum collection, learning more about the reptile’s biology.

Professor Martill explained:

“There are a number of things that make this animal special, not least of which is its unusual rib cage and small flippers.  It may have swum with a distinctive style from other ichthyosaurs.”

Our congratulations to Dr Steve Etches and all the team at the amazing Etches Collection museum on the Dorset coast.

New CollectA Models for 2021 Video Review

By | December 8th, 2020|Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Everything Dinosaur videos, Main Page, Photos of Everything Dinosaur Products, Press Releases|0 Comments

New CollectA Models for 2021 Video Review

Everything Dinosaur has produced a video review of the last batch of new for 2021 prehistoric animal models to be introduced by CollectA.  In our final video in this series, we provide further information on the 1/40th scale CollectA Deluxe Dilophosaurus, the 1/20th scale Doedicurus replica and the stunning Pravitoceras, an ammonite associated with the Late Cretaceous of Japan.

Everything Dinosaur’s Video Review – The Last Three New for 2021 CollectA Prehistoric Animal Models

All three of the figures featured in Everything Dinosaur’s YouTube video will be available from the UK-based company in the middle of 2021.

Question of the Day

As with the other three videos that Everything Dinosaur has produced looking at the new prehistoric animal models from CollectA, the team have been keen to provide a little more scientific information about each model.   For example, with the new CollectA Deluxe 1:40 scale Dilophosaurus, the narrator explains why this figure has been give enlarged head crests.  The reasoning behind the lack of sharp spikes on the tail of the armoured Doedicurus is highlighted and when discussing the Pravitoceras figure the narrator comments upon the differences between homomorphic and heteromorphic ammonites.

In addition, we include a “question of the day” and on this occasion, in honour of the new for 2021 CollectA Deluxe Doedicurus we ask: “what other prehistoric mammal would you like CollectA to make a model of?”

The New CollectA Deluxe Dilophosaurus is Based on the Latest Scientific Research

CollectA Dilophosaurus, Doedicurus and the New Ammonite Figure Pravitoceras

CollectA will be adding a total of eleven prehistoric animal models to their already extensive product portfolio for 2021.  They will also add a new set of mini dinosaur and prehistoric animal figures that Everything Dinosaur reviewed in an earlier blog post and video: CollectA New Models for 2021 – Part 3.

In the Doedicurus section, the narrator looks at the closest living relatives of these extinct herbivores and comments how the first fossils of these beasts came to be scientifically described by such luminaries as Charles Darwin and Richard Owen.

A spokesperson from Everything Dinosaur commented:

“We have produced four videos in total.  Each video examines new for 2020 CollectA prehistoric animals and these videos along with more than 175 others can be found on the Everything Dinosaur YouTube channel.  In our last CollectA model review we looked at the scientific data that led to the revised Dilophosaurus dinosaur model, examined different types of ammonite comparing the 2020 CollectA Pleuroceras figure with the soon to be released Pravitoceras and highlighted the 1:20 scale Doedicurus.”

Two New South American Titanosaurians

By | December 7th, 2020|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles, Photos/Pictures of Fossils|0 Comments

Two New South American Titanosaurians

The last type of sauropod to have lived were the Titanosauria, a clade consisting of a variety of taxa that were geographically widespread.  Fossils of titanosaurs have been found on every continent.  These long-necked herbivores seem to have been particularly successful in South America, with some of the largest tetrapods of all time – Argentinosaurus, Patagotitan and Dreadnoughtus known from this continent.

A team of scientists based in Argentina recently published a paper describing two new South American titanosaurs from the province of La Rioja located in the north-west of that country.  The dinosaurs named Punatitan coughlini and Bravasaurus arrierosorum, help to fill a gap between the types of titanosaurs associated with Patagonia and south-western Brazil, the two main locations associated with Titanosauria fossil discoveries from South America.

Dinosaurs from the Andes – Titanosaurs Demonstrate Philpatry

The fossil material representing three individuals was found in the Upper Cretaceous red beds of the Quebrada de Santo Domingo locality in the Andes of La Rioja province.  In addition, a large number of titanosaurian egg clutches and eggshells were recovered.  Such was the abundance of eggshell found that this location is regarded as one the largest dinosaur nesting sites known in the world.  These fossils help to support the theory that these types of dinosaurs returned to the same, favoured nesting area year after year, the titanosaurs demonstrated philopatry (the tendency of an organism to habitually return to the same location, usually to breed or to nest).

Phylogenetic Analysis

A phylogenetic analysis undertaken by the research team suggests that both Bravasaurus and the much larger Punatitan have affinities with both Patagonian and Brazilian titanosaurs.  The discovery of these two genera, both classified within the sub-clade of the Rinconsauria, supports the hypothesis of a close relationship between titanosaurian faunas in South America during the Late Cretaceous.

A New Tyrannosauroid from Northern China

By | December 5th, 2020|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Photos/Pictures of Fossils|0 Comments

A New Tyrannosauroid from Northern China – Jinbeisaurus wangi

Over the last two years or so, there have been a number of exciting dinosaur discoveries.  Some amazing dinosaur fossils have been found and scientifically described, but sometimes mere scraps of bone, just fragmentary remains can be enough to set the pulses of vertebrate palaeontologists racing.  Take for example, the new genus of Late Cretaceous tyrannosaur from northern China that was formally described back in April.  At around 5-6 metres in length Jinbeisaurus wangi, may not be the largest carnivorous dinosaur known from Upper Cretaceous deposits from Asia, but it does represent the first theropod to be described from the Chinese province of Shanxi.

An initial assessment led to the jaw bones, partial pubis (bone from the hip) and incomplete dorsal and cervical vertebrae, being assigned to the Tarbosaurus genus, but unique characteristics associated with the shape and proportion of the maxilla led to erection of a new species.

The Genus Has Been Erected Based on Autapomorphies Identified in the Jaws

Not a Juvenile Tarbosaurus

The scientific paper describing Jinbeisaurus (pronounced jin-bay-sore-us), was published in late 2019 in the journal “Cretaceous Research”, although it had originally been submitted in the spring, only to be revised before final publication.  When the fossil material was found near the city of Yangjiayao, Tianzhen County, Shanxi Province, in northern China, it was suggested that the bones could represent a juvenile Tarbosaurus.  This new dinosaur, J. wangi adds to the known diversity of tyrannosauroids in Asia and represents the first theropod to have been discovered in Shanxi Province, although isolated teeth representing carnivorous dinosaurs are known from the area.

Estimated to have measured around 5-6 metres long, Jinbeisaurus wangi is regarded as more derived than Suskityrannus (S. hazelae) a tyrannosauroid from New Mexico named earlier in 2019.

Atopodentatus unicus for Fossil Friday

By | December 4th, 2020|Adobe CS5, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Photos/Pictures of Fossils|0 Comments

Atopodentatus unicus for Fossil Friday

Aware of the hastag “#FossilFriday”, it seems appropriate that we should post up a picture of a fossil on Friday, as we approach the busiest time of year for the packing and despatching of models and figures that have been inspired by the fossil record.  Team members at Everything Dinosaur have chosen to post up a photograph of the bizarre, marine reptile, known from the Middle Triassic of south-western China called Atopodentatus.  It seems appropriate that with all the amazing fossils that are in museum collections around the world, we should post a photograph of one of the strangest Mesozoic vertebrates known to science.

The Fossilised Remains of Atopodentatus unicus

Atopodentatus fossils.

Bizarre Triassic marine reptile!   The beautifully preserved and articulated remains of Atopodentatus unicus from Yunnan Province in south-western China.  Note the close-up view of the strange skull and jaws, that were originally interpretated as being a zipper-like feeding apparatus.  Further fossil discoveries made two years after the initial description of this marine reptile, revealed that Atopodentatus had jaws shaped like a hammerhead.

Picture Credit: Long Cheng/Wuhan Institute of Geology and Mineral Resources

Note

Scale bar in main photograph equals 20 centimetres, scale bar for close-up of skull equals 3 centimetres.

Named in 2014 (Long Cheng et al), Atopodentatus had jaws shaped like a hammerhead, superficially similar to that seen in an extant Hammerhead shark.  Unlike the shark, Atopodentatus is believed to have been herbivorous.  It used its comb-like teeth to rasp away at rocks, feeding on algae and seaweed.

When the scientific paper was published, it was noted that Atopodentatus represents the oldest known record of herbivory within marine reptiles.

Chinese model and figure manufacturers PNSO will be introducing a mid-size replica of this strange animal.  This figure will be in stock at Everything Dinosaur in a few weeks (estimated to be in stock by the end of December 2020).  It is great to see PNSO adding a second replica of the bizarre Atopodentatus to their model range.

PNSO Have Made Another Model of the Strange Chinese Marine Reptile Atopodentatus (A. unicus)

It therefore seems appropriate to post up pictures of the Middle Triassic record-breaker Atopodentatus unicus for Fossil Friday.

PNSO to Introduce a Sinoceratops Model

By | December 3rd, 2020|Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|0 Comments

PNSO to Introduce a Sinoceratops Model

PNSO the model and figure manufacturer will be adding a replica of the Chinese horned dinosaur Sinoceratops to their mid-size model range in 2021.  Say hello to the PNSO Prehistoric Animal Models That Accompany Your Growth 40 A-Qi the Sinoceratops.  This stunning, new model of Sinoceratops will be available from Everything Dinosaur in the early part of next year (2021).

PNSO are Introducing a Model of a Sinoceratops to their Mid-size Model Range

This is the second horned dinosaur figure to be announced by Everything Dinosaur in collaboration with PNSO this week after the Machairoceratops was premiered in our blog with a post on November 30th.  To read about the new for 2021 Machairoceratops figure: New PNSO Model Machairoceratops.

Images of the new Sinoceratops were revealed on Everything Dinosaur’s Facebook page earlier this week.

Named in 2010

Sinoceratops was formally named and described in 2010 (Xu Xing et al), from fossils discovered in 2008 in eastern China.  It might be the only ceratopsid known from outside North America, (the validity of Turanoceratops tardabilis from Uzbekistan remains uncertain).  It is therefore fitting that a Chinese manufacturer should add a replica of “Chinese horned face” to their product portfolio.

PNSO A-Qi the Sinoceratops Model Measurements

As this figure will be part of the ever increasing range of mid-size models offered by PNSO, no scale for this figure is given.  The model measures a fraction over 15 cm long, and those magnificent parietals are 9.4 cm off the ground.  Based on the maximum size of an adult Sinoceratops (6 metres in length), we estimate that this figure is in approximately 1:40 scale.

The Pathology of an Iconic Parasaurolophus

An Unlucky Parasaurolophus – ROM 768

A study of the holotype of the iconic duck-billed dinosaur Parasaurolophus (P.walkeri) has revealed that some of these dinosaurs led very tough lives.  Tell-tale evidence preserved in the fossilised bones suggest that this particular specimen ROM 768, suffered a major trauma, but survived, at least for a little while after the incident.

PhD student Filippo Bertozzo from the School of Natural and Built Environment at Queen’s University Belfast, examined the skeleton of the Parasaurolophus which has been on display at the Royal Ontario Museum (Canada).  The articulated specimen (ROM 768), represents the almost complete remains of an adult animal, only elements from the lower limbs and the tail are missing.

The fossils were discovered in 1920 in Upper Cretaceous sediments exposed along the Red Deer River of southern Alberta.  The material represents the first fossils of the genus Parasaurolophus to be reported and studied.

Injured by a Falling Tree

The morphology of the dinosaur’s neck had long intrigued scientists and scientific illustrators.  Once thought to have a graceful, swan-like neck most palaeontologists now think that Parasaurolophus had a thick, bulky neck, one capable of supporting that huge, hollow crest for which this dinosaur is famous for.

Student Filippo explained:

“Our research using paleopathological markers, which help us study the diseases of ancient humans and fossil animals, means we are now fairly certain how this iconic dinosaur would have really looked.  The ROM 768 suffered numerous injuries which suggest a major incident of trauma before its death and we think a heavy object such as a tree may have fallen on top of the animal, perhaps during a storm.”

Reconstructing the Neck of an Ornithopod

The research has shown that members of the Ornithopoda, including duck-billed dinosaurs, iguanodonts and other related genera were prone to a number of injuries and diseases.

Commenting on ROM 768, the PhD student added:

“Damage to the muscles resulted in a disc-shaped overgrowth on the tip on the bony part of one its vertebrae in its neck.  We interpreted the disc as a secondary enlargement of the base of the nuchal ligament, a large elastic structure that supports the neck and the head.  This enabled us to reconstruct the anatomical structure of the neck, revealing that it was strong and muscular to support its head.”

The study of the iconic Parasaurolophus specimen revealed broken bones in the pelvis, ribs and spine.  The scientists also found evidence of a lesion in the mouth that may have been caused as a result of a heavy object falling on the animal.

The injuries show signs of healing, demonstrating how tough and resilient these types of dinosaurs were.  The Parasaurolophus (ROM 768), survived for several months or perhaps some years after the traumatic event.

Professor Eileen Murphy, a bioarchaeologist in Queen’s, stated:

Palaeopathology has been a relatively neglected aspect of palaeontology until recent years.  The study of ROM 768 clearly demonstrates the value of this approach for reconstructing the quality of life of dinosaurs and the threats from the natural environment they may have faced on a daily basis.”
