Schleich Animantarx Model Reviewed by JurassicCollectables

The latest video to be produced by those creative people at JurassicCollectables features one of the new for 2019 Schleich prehistoric animal figures – the Schleich Animantarx.  The Animantarx is described as adorable and as it represents an armoured dinosaur that grew to a length of approximately three metres.  The model works well in scale with JurassicCollectables regular “off-colour Alan”, who makes an appearance towards the end of the review.

An Adorable Animantarx

The narrator describes this model as an “adorable Animantarx” and it certainly has an appeal.  The figure is nicely proportioned and the wet-looking gloss added to the black eyes provides this replica with a certain charm.  It is described as “a cute looking dinosaur” and it is hard to disagree.

Animantarx

The narrator correctly points out that this member of the Nodosauridae family was named and described relatively recently (1999).  It is known from very fragmentary fossils, including a partial skull and a piece of fossilised jaw.  This dinosaur had a distinctive domed skull and tiny horns behind the eyes.  Features that can be seen in the close-up view of the head in the picture above.  It is this attention to detail that elevates this armoured dinosaur model.  Clearly, the Schleich design team have worked hard to produce a model that reflect scientific understanding.   The model may have flaws, but as the narrator points out, there is much to be admired when it comes to examining the dermal armour, the skin tones and the detailing of the body scales.

Comparing Schleich Prehistoric Animal Models

One of the great benefits of a JurassicCollectables video review is that it enables viewers to see up close a new figure and to compare it to other recent model introductions.  In this video review, the new for 2019 Schleich Spinosaurus figure is shown and the 2019, re-painted Dimetrodon makes an appearance.  Both the Dimetrodon and the Schleich Spinosaurus have also been recently reviewed on the JurassicCollectables channel.  As mentioned earlier, “off-colour Alan” appears in the video as well.  It is always a pleasure to see “off-colour Alan”.

Iconic Feather Fossil Did Not Belong to Archaeopteryx

By | February 5th, 2019|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Photos/Pictures of Fossils|0 Comments

Single Feather Not From Archaeopteryx

One of the most significant fossils to have ever been found, an iconic fossil in vertebrate palaeontology – a single fossilised feather from the Upper Jurassic Solnhofen limestone, is not quite what it seems.  The feather, long thought to be from an Archaeopteryx, is probably not from the “urvogel” at all.  The feather most likely was lost by a dinosaur, before it was blown into a shallow, calm lagoon and preserved as a carbonised film for 150 million years.

The Iconic Single Feather Fossil – Once Synonymous with Archaeopteryx is Not What it Seems

An international research team which included Dr Michael Pittman (University of Hong Kong), have applied a novel, high-tech, imaging method called Laser-Stimulated Fluorescence (LSF), to  help solve a 150-year-old mystery and to confirm that this feather was not from Archaeopteryx.

Discovered in 1861

The specimen was discovered in 1861 and actually consists of a slab and counter slab component, housed in museums located in Berlin and Munich.  A year later, the fossil feather was formally described and heralded as coming from an Archaeopteryx (A. lithographica), although unlike most feather impressions associated with the dozen or so Archaeopteryx specimens known to science, this feather was preserved as a dark, carbonised film.  This was the first fossil feather ever discovered and at the time fossils of Archaeopteryx were heralded as evidence of a “missing link”, supporting Darwin’s recently published theory of natural selection.

The detailed scientific description published in 1862 commented upon a rather long quill visible on the fossil, but this is unseen today.  Even recent X-ray fluorescence and UV (ultraviolet), imaging studies did not end the controversy of the “missing quill”.  The original existence of this quill has therefore been debated and it was unclear if the single feather represented a primary, secondary, or primary covert feather from Archaeopteryx.

Writing in the academic journal Scientific Reports, the researchers outline their work using the LSF technology and demonstrate its potential for providing new information about extensively studied fossil specimens.  The application of Laser-Stimulated Fluorescence is being developed by Thomas G Kaye of the Foundation for Scientific Advancement, Sierra Vista, Arizona (USA) and Dr Pittman.

Dr Pittman stated:

“My imaging work with Tom Kaye demonstrates that important discoveries remain to be made even in the most iconic and well-studied fossils.”

Detecting the Geochemical Presence of the Lost Quill

The application of LSF technology permitted the scientists, which included lead-author of the study Tom Kaye, to detect the geochemical halo from the rachis, matching the 1862 description.

The shape of the feather has led the researchers to discount the idea that it came from an Archaeopteryx.  Instead, they conclude that it probably came from an unknown species of feathered dinosaur that lived alongside Archaeopteryx in the Solnhofen Archipelago.

Daniela Schwarz, a co-author of the scientific paper based at the Museum für Naturkunde, Berlin, commented:

“It is amazing that this new technique allows us to resolve the 150-year-old mystery of the missing quill.”

This new insight into an iconic fossil specimen also suggests that the diversity of feathered dinosaurs was likely higher in the ancient island archipelago than previously thought.

Tom Kaye added:

“The success of the LSF technique here is sure to lead to more discoveries and applications in other fields.  But, you’ll have to wait and see what we find next!”

The New for 2019 Papo Spinosaurus

By | February 4th, 2019|Dinosaur Fans, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|2 Comments

Everything Dinosaur will be Stocking the New for 2019 Papo Spinosaurus

The new for 2019 Papo Spinosaurus dinosaur model will be available to buy from Everything Dinosaur in the summer of 2019.  This awesome prehistoric animal model was revealed last week by the French manufacturer and this large dinosaur figure has already garnered a great number of positive comments given that it depicts Spinosaurus as a semi-aquatic quadruped, an ecological niche advocated in a ground-breaking scientific paper published on Spinosaurus aegyptiacus back in 2014.  The new Papo Spinosaurus model will be coming into stock in June.

A Secret Papo Project

The Spinosaurus has been kept under wraps by the senior management team at Papo, not even staff members at the company knew about the model’s existence until it was revealed at an exhibition last week.  One of Papo’s best-selling dinosaur models of all time is their original Spinosaurus figure, but this model depicted this Late Cretaceous North African Theropod as a biped, many palaeontologists now believe that Spinosaurus was a specialised piscivore (fish-eater), that moved around on all fours and spent much of its time in rivers and lakes.

The New for 2019 Papo Spinosaurus

The new Papo figure, will have limited availability, Papo intend to produce all the models in a single production run, so this new Spinosaurus will be much rarer and more difficult to obtain than the rest of the Papo “les dinosaures” figures.  The Papo Spinosaurus (2019), will also be excluded from the 2019 catalogue, as Everything Dinosaur understands the situation, only a few selected distributors of Papo’s products will be able to gain access to this new replica.

An Exciting New Addition to the Papo Model Range – but with Limited Availability

In Praise of “Carboniferous Giants and Mass Extinction”

By | February 3rd, 2019|Adobe CS5, Book Reviews, Dinosaur and Prehistoric Animal Drawings, Main Page|0 Comments

A Guide to the Late Palaeozoic Ice Age World

Long journeys and hours waiting around in train stations and airport terminals have been made bearable thanks to an excellent book written by George R. McGhee Junior, a Distinguished Professor of Palaeobiology at Rutgers University.  The book is “Carboniferous Giants and Mass Extinction”.  At this time of year, Everything Dinosaur team members seem to have to undertake a lot of travelling, what with their project work and teaching commitments, this eminently informative and enjoyable book has proved a worthy travelling companion.

“Carboniferous Giants and Mass Extinction” an excellent book that explains the science behind our knowledge of the Carboniferous flora and fauna and explores the impact of the End-Permian mass extinction event.

Artwork by Richard Bizley

One of the ironies of having read this book from cover to cover is that we have only just noticed that the front cover artwork showing a typical Late Carboniferous rainforest dominated by lycophyte scale trees, giant horsetails such as Calamites and marattialean tree ferns, was produced by our dear friend Richard Bizley.  Richard is a highly respected artist, he produces exquisite prehistoric scenes as well as landscapes and science fiction illustrations.  The huge millipede in the foreground is Arthropleura armata, which is estimated to have grown in excess of three metres long.  This giant arthropod is illustrated inside the book too, Mary Persis Williams, another highly respected scientific illustrator, shows the scale of A. armata by comparing it to an extant American Alligator (A. mississippiensis).

To read Everything Dinosaur’s review of this beautifully crafted book: Our Review of “Carboniferous Giants and Mass Extinction”

An Insight into an Alien World

Life on Earth in the Carboniferous and Permian was very different from ecosystems today.  As well as the giant arthropods found in terrestrial and marine environments, there were alien-looking plants and bizarre vertebrates some of which (synapsids), were the distant ancestors of mammals.  Top predators in the Carboniferous forests and Early Permian swamps included salamander-like amphibian batrachomorphs such as the monstrous Eryops megacephalus,  which grew to more than two metres in length and was capable of swallowing a small child whole (if humans had lived in the Palaeozoic).

Thesaurus and a Dinosaur

Sorry, we finally gave into temptation and posted up a picture that we had been meaning to share on our various social media platforms for some time.  A dinosaur model posed on a Thesaurus which is was on our reference shelves in our offices, but we could not resist anymore…

A Thesaurus is a reference work that allows you to look up different ways of saying something.  By looking up a word in a Thesaurus a list of synonyms will be provided for that term, other words that have the same meaning or mean something very similar.  For example, the dinosaur in the picture is a bipedal carnivore, if you were to look up the term “carnivorous” in a Thesaurus it would suggest alternative words to use such as zoophagous, meat-eating and creophagous.

The dinosaur model in the photograph is from the CollectA Prehistoric Life range of figures, it is the CollectA Tarbosaurus.  The picture shows a Tarbosaurus and a Thesaurus together.

Pachyrhinosaurus perotorum – New Research is Published

By | February 1st, 2019|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

Puzzling Pachyrhinosaurs – The Remarkable Pachyrhinosaurus perotorum

Researchers from the Perot Museum of Nature and Science (Dallas, USA), in collaboration with the University of Toronto (Canada), have published an update on their research into one of the most remarkable Late Cretaceous dinosaurs known to science.

Back in 2011, Everything Dinosaur reported that field work in the high Arctic led by palaeontologists from the Perot Museum of Nature and Science had uncovered the fossilised remains of at least ten individual dinosaurs representing a new species of Ceratopsian.  This horned dinosaur, a Pachyrhinosaur, was named Pachyrhinosaurus perotorum and it became the third species to be assigned to this centrosaurine genus.  With numerous specimens to study, the palaeontologists could gain a fresh perspective on how horned dinosaurs changed as they grew up and develop a better understanding of the cranial ornamentation associated with the Ceratopsidae.

Updating Their Findings

The authors of the original scientific paper describing P. perotorum, Anthony Fiorillo and Ronald Tykoski, have published a new report in conjunction with Kentaro Chiba of the Department of Ecology and Evolutionary Biology at the University of Toronto, updating their research and providing more information on how this species can be distinguished from the two other species of Pachyrhinosaurus.  The continued preparation of fossil specimens collected from the type locality, the  Kikak-Tegoseak Quarry (Prince Creek Formation), has produced more skull elements to study.  The researchers note that their original reconstruction of the type parietal bone was incorrect, the parietal along with the squamosal bone form the neck frill in horned dinosaurs.  The parietal of P. perotorum is similar to the parietal bones of the other species – P. canadensis and P. lakustai.

It is postulated that Pachyrhinosaurus perotorum can be identified by an upturned tip of the rostrum, a dorsally shifted rostral bone lacking a sharply downturned, parrot-like beak and an enlarged median ridge at the posterior end of the nasal boss.  Other differences in cranial morphology are also tentatively proposed in the new scientific paper, published in the Journal of Systematic Palaeontology.

The Sister Taxon of P. canadensis

A cladistic analysis undertaken by the team using this new dataset in conjunction with previous research confirms that the Pachyrhinosaurus genus is monophyletic (all descended from a common ancestor) and that Pachyrhinosaurus canadensis is the sister taxon to P. perotorum.  In addition, this research supports the idea that parietal and squamosal frill ornamentations alone do not adequately address the variables in craniofacial morphology needed to distinguish between species of Pachyrhinosaurus.

The continuing research into horned dinosaurs that lived at high latitudes is helping palaeontologists to gain a better understanding of a unique ecosystem that existed towards the end of the dinosaur age.  Pachyrhinosaurus perotorum is not only the youngest Pachyrhinosaur species known, it is also the geologically youngest known centrosaurine.  With three species assigned to the genus, Pachyrhinosaurus is the most speciose of all the Centrosaurinae genera.

A spokesperson from Everything Dinosaur commented:

“Pachyrhinosaurus perotorum holds a special place in Ceratopsidae research.  It lived at a higher latitude than any other horned dinosaur known to science and, as a consequence, had to endure some very tough and harsh climatic conditions.  Whether this dinosaur was a seasonal migrant to the area in summer to take advantage of the 24-hours of daylight that permitted abundant plant growth, or whether this reptile was a permanent resident remains uncertain.  However, the discovery of the fossilised remains of a juvenile at the Kikak-Tegoseak Quarry, suggests that this dinosaur could have been indigenous to northern Alaska during the Maastrichtian faunal stage.”

A Newly Described Archosauromorph from Antarctica

By | January 31st, 2019|Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Geology, Main Page, Photos/Pictures of Fossils|0 Comments

Antarctanax shackletoni – Rise of the Archosaurs

A team of researchers, including scientists from the Field Museum (Chicago, USA), the University of Witwatersrand (South Africa) and the Burke Museum (University of Washington, USA), have published a scientific paper announcing the discovery of an archosauriform archosauromorph, that roamed Antarctica in the Early Triassic.  The fossil discovery suggests that early Archosaurs were more geographically widespread than previously thought and demonstrates that the biota of Antarctica may have been very different from other parts of the super-continent Pangaea as the planet recovered from the End-Permian mass extinction event.

A Diverse Fauna in Antarctica During the Early Triassic

The illustration above depicts a typical ecosystem that existed in Antarctica approximately 250 million years ago.

Along the banks of a river, three Archosaur inhabitants of the dense Voltzia conifer forest cross paths, Antarctanax shackletoni attempts to sneak up on an early titanopetran insect, an archosauromorph Prolacerta rests on a log, and an enigmatic large Archosaur pursues two unsuspecting Dicynodonts, (Lystrosaurus maccaigi).

“Antarctic King”

Commenting on the significance of the discovery of the iguana-sized animal, co-author of the scientific paper Brandon Peecook (Field Museum) stated:

“This new animal was an Archosaur, an early relative of crocodiles and dinosaurs.  On its own, it just looks a little like a lizard, but evolutionarily, it’s one of the first members of that big group.  It tells us how dinosaurs and their closest relatives evolved and spread.”

The fossil skeleton is far from complete.  The material was collected from a site representing Lower Fremouw Formation deposits in the central Transantarctic Mountains.  The fossils consist of cervical and dorsal vertebrae, a single humerus and foot bones.  The reptile has been named Antarctanax shackletoni.  The genus name means “Antarctic King”, although this ancient, basal member of the group of reptiles that was to give rise to the dinosaurs, pterosaurs, crocodiles and birds, was probably not an apex predator.  This cannot be stated with certainty, after all, only one fossil specimen has been found, but Antarctanax shackletoni co-existed with a number of other vertebrates including amphibians, synapsids and at least one large archosauriform, which may have been the top predator.

The species name honours the polar explorer Ernest Shackleton.  It is suggested that Antarctanax hunted insects as well as smaller vertebrates.

Antarctanax – Where it Lived and When

Brandon Peecook, a member of the Integrative Research Centre, at the Field Museum explained that this fossil find (made in the 2010/11 field season), is significant because it demonstrates that the ecosystem in Antarctica bounced back relatively quickly after the End-Permian mass extinction event and that  archosauriforms were quite widespread at this time.

He stated:

“The more we find out about prehistoric Antarctica, the weirder it is.  We thought that Antarctic animals would be similar to the ones that were living in southern Africa, [Karoo Basin biota] since those landmasses were joined back then, but we’re finding that Antarctica’s wildlife is surprisingly unique.”

The fauna of the Lower Fremouw Formation traditionally has been considered to represent a subset of the Lystrosaurus Assemblage Zone of the Karoo Basin of southern Africa, with discrepancies largely a result of pronounced differences in sampling intensity.  However, a review of recent changes to the fauna, as well as a reassessment of occurrences based on older literature, indicates that significant discrepancies, including the co-occurrences of taxa known from both earlier and later in time and the presence of endemic forms in Antarctica, exist between the faunas of the Lystrosaurus Assemblage Zone and Lower Fremouw Formation.  In essence, Antarctica 250 million years ago had a different ecosystem to that associated with the contemporaneous Karoo Basin deposits.

As life on Earth recovered in the Early Triassic, so the Archosaurs rapidly diversified and laid the foundation for the evolution of the Dinosauria, Pterosauria, crocodiles and those other Archosaurs still very much with us today – the Aves (birds).

Post-doctoral Fellow Peecook, went on to state:

“Before the mass extinction, Archosaurs were only found around the Equator, but after it, they were everywhere.   Antarctica had a combination of these brand-new animals and stragglers of animals that were already extinct in most places, what palaeontologists call ‘dead clades walking.’  You’ve got tomorrow’s animals and yesterday’s animals, co-habiting in a cool place.”

The fact that scientists have found Antarctanax helps bolster the idea that Antarctica was a place of rapid evolution and diversification after the mass extinction.

A spokesperson from Everything Dinosaur commented:

“Antarctica is an extremely difficult part of the world to prospect for fossils.  However, as more of the frozen continent is mapped and explored, so more fossil discoveries are going to occur.  Antarctanax shows that there was a diverse faunal assemblage on this part of Pangaea during the Early Triassic and this discovery will help palaeontologists to plot the evolution and distribution of Archosaurs.”

Dimetrodon and Giganotosaurus (Schleich) Reviewed by JurassicCollectables

Those talented people at the JurassicCollectables YouTube channel have released another video, this time, it is a review of two of the new for 2019 Schleich prehistoric animal figures, both re-paints, the Schleich Giganotosaurus and the Schleich Dimetrodon.

New for 2019/New Colour Schemes

Both these figures are new colour schemes of previously introduced sculpts.  Providing re-painted versions of existing models can help to broaden a product range and provides a contrast to previously introduced figures.  For example, the new for 2019 Schleich Giganotosaurus has an altogether darker colour scheme than the Schleich Giganotosaurus (orange) that was launched in 2015.  The narrator points this out and goes on to provide a detailed analysis of the subtle use of airbrushing as well as commenting upon the darker colour palette associated with the skull and the airbrushing to bring out the textures in the neck.

Five New Schleich Prehistoric Animals

The Giganotosaurus and the Dimetrodon are two of the five new Schleich prehistoric animals to be introduced in the first part of 2019.  We will post up details of other Schleich models due to be introduced in July, but for the meantime, dinosaur fans have a Spinosaurus, Dimorphodon, an armoured dinosaur (Animantarx) and these two prehistoric animals to collect.

The Schleich Dimetrodon (2019)

Dimetrodon seems to be a staple in prehistoric animal model ranges and is often described incorrectly as a dinosaur.  However, this Permian predator from Schleich is praised by the video narrator for its excellent airbrushing and fine detail, especially on the sail.  The texture on the animal’s flank and the carefully painted eyes are highlighted.  JurassicCollectables have a long history of producing dinosaur model reviews, they suggest that the colour scheme for the new for 2019 Dimetrodon reflects the original “Jurassic Park” Dimetrodon model that was introduced in the 1990’s.  The narrator comments that the figure has been painted in naturalistic colours, reminiscent of many living lizards.

Preparing to Introduce a New Oviraptorid

By | January 29th, 2019|Dinosaur Fans, Main Page, Palaeontological articles, Press Releases|0 Comments

Preparing to Introduce a New Oviraptorid

As Everything Dinosaur team members prepare to write about the formal scientific description of a new species of oviraptorid from the Late Cretaceous of southern Mongolia, we have been brushing up on our knowledge of the Oviraptorosauria clade.

No Need to Get into a Flap over the Oviraptorosauria

Is this an example of dinosaur courtship?

The Oviraptorosauria is a very diverse clade of Theropods.

An Unusual Branch of the Maniraptora

The Oviraptorosauria clade is an atypical branch of the maniraptoran Theropods.   They are characterised by short, deep skulls, jaws which lack teeth (edentulous in derived, advanced members of the clade), short, stunted tails and tail bones with lots of air sacs within them (pneumatised proximal caudal vertebrae).  The first of these dinosaurs were formally named and described in the 1920’s (Oviraptor and Chirostenotes), over the last three decades, numerous new members of this clade have been identified, mostly from Upper Cretaceous strata.

The  oviraptorosaurs are likely to have originated in Asia.  The earliest fossil record of these dinosaurs is reported from the Lower Cretaceous Yixian Formation of China.  It is likely that these dinosaurs were feathered and most of them were relatively small and light-weight.   However, there were exceptions to this rule, such as the huge Gigantoraptor (Gigantoraptor erlianensis), that stood nearly as tall as a giraffe.  Gigantoraptor was named and described in 2007: New Giant Chinese Dinosaur Described.

Three Families within the Oviraptorosauria

Palaeontologists consider the Oviraptorosauria to be a very diverse clade with numerous taxa, but it can be broadly classified into three distinct families:

  1. The Avimimidae  – which for the moment contains a single genus (Avimimus), with two species from the Nemegt Formation of Mongolia, although the provenance of the first fossils associated with this genus is not clear.
  2.  The Caenagnathidae – which are known from North America and Asia with numerous genera including the giant Gigantoraptor erlianensis.
  3. The Oviraptoridae – which are only known from Asia, although there are more genera recognised than within the more geographically widespread caenagnathids.

Of these three dinosaur families, it can be argued that the Oviraptoridae are the best understood.  Many genera are known from nearly complete fossil skeletons, whilst in the case of most caenagnathids, these dinosaurs are mostly known from highly fragmentary and far from complete material.

We look forward to publishing an article in the very near future describing a new member of the Oviraptoridae from the famous Upper Cretaceous deposits of the Nemegt Formation of Mongolia.

Note

Our article has been published, say hello to a new Asian, Late Cretaceous oviraptorid – Gobiraptor minutus.

CollectA Supreme Deluxe Caiuajara

Everything Dinosaur team members are preparing for the arrival in the next few weeks or so of the CollectA Supreme Deluxe Caiuajara pterosaur model.  This beautiful and most impressive figure of a Cretaceous flying reptile from Brazil is going to be one of the first of the new for 2019 CollectA figures that arrive in our warehouse.  As part of our preparations, team members have been busy researching and writing a fact sheet all about this weird and wonderful member of the Pterosauria.

A CollectA Speciality

Large replicas of pterosaurs are becoming a bit of a CollectA speciality.  When stocks of this 2019 figure arrive at our warehouse, it will be joining two other CollectA Supreme Deluxe pterosaur models.  CollectA introduced a 1:4 scale replica of a Chinese member of the Ornithocheiridae family – Guidraco back in 2015.  This was followed in 2017 by the award winning CollectA Supreme Deluxe Dimorphodon model.  All three models will have moveable, articulated jaws.

Pronouncing Caiuajara

When this pterosaur was formally named and described back in 2014, it caused quite a sensation amongst palaeontologists who specialise in studying the Pterosauria.  It is quite usual to have just a few fragments of bone to study, but in this case, the fossilised remains of more than forty individuals were recovered from a dig site in south-eastern Brazil.  This flying reptile had a remarkable crest, shaped a bit like the wing of a butterfly.  The fossil site was interpreted as a stop-over location as these animals migrated.  They were very competent flyers travelling great distances, so it is appropriate that the new for 2019 Caiuajara figure is travelling a great distance from the factory to our UK warehouse.

The fact sheet we are going to produce will also include a guide to pronunciation.  The genus name of this pterosaur is pronounced “Kay-you-ah-jar-rah”.  The CollectA Supreme Deluxe Caiuajara with moveable jaw measures around 19 centimetres in length and with that impressive and colourful crest the model’s height is about 23.5 cm.

We look forward to welcoming this model into our CollectA portfolio.
