New PNSO Pinacosaurus Dinosaur Model

Everything Dinosaur in collaboration with PNSO announce that in 2021 a museum quality replica of Pinacosaurus will be added to the PNSO model range.  Over the last few months, Everything Dinosaur has released information about a huge range of new PNSO dinosaur models, including lots of armoured dinosaurs such as new Tuojiangosaurus, Borealopelta, Sauropelta and Miragaia.  It is wonderful to see a Chinese manufacturer adding an Asian member of the Ankylosauridae family to their product portfolio.

This new Pinacosaurus dinosaur model will be in stock at Everything Dinosaur in 2021.

Pinacosaurus grangeri

Named and described in 1933 by the American palaeontologist C. W. Gilmore, the first fossils of this medium-sized member of the ankylosaur family were discovered by the famous American Museum of Natural History Museum expedition to the Gobi Desert of Mongolia in the early 1920s.  The genus name translates from the Latin as “plank lizard”, a reference to the small, plank-like dermal scutes associated with the top of the skull.  The trivial or species name honours Walter Wallis Granger one of the scientists involved with the American Museum of Natural History expedition.  It was Granger who found the first fossilised remains of this armoured dinosaur in 1923.

The dinosaur (P. grangeri) is estimated to have been around 5 metres long when fully grown.  Estimates of body weight vary, Gregory S. Paul estimates a body weight of 1,900 kilograms, whereas other researchers, suggest that this armoured dinosaur was relatively lightly-built when compared to similarly sized ankylosaurines such as Tarchia (T. kielanae), Ziapelta (Z. sanjuanensis) and Aletopelta (A. coombsi).

Lots of Specimens to Study

The design at PNSO have been spoilt for choice when it comes to Pinacosaurus.   There are numerous fossil specimens to study including almost complete individual skeletons.  Most of the fossil material represents juveniles and as these remains tend to be found in groups, it has been suggested that these herbivores roamed their desert environment in small herds.

Inspired by the Australian Mountain Devil?

Everything Dinosaur team members noted the striking similarity between Bart the PNSO Pinacosaurus model and the extant Australian agamid lizard known as the Mountain Devil or Moloch (Moloch horridus).  The colours chosen for the PNSO model are reminiscent of the colour of the Moloch, a thorny lizard which is widespread in Australia.

Oviraptorid Overturns Ideas on Late Stage Egg Incubation

By | January 9th, 2021|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles, Photos/Pictures of Fossils|0 Comments

Fossil of Dinosaur Sitting on Eggs (Late Stage Incubation)

Fossils of dinosaurs are rare, fossils of articulated dinosaur skeletons rarer still and any fossils that preserve evidence of behaviour, these are amongst the rarest of all, truly scientific treasures.  A newly published paper describes the fossilised remains of a Late Cretaceous oviraptorid from east China’s south-eastern Jiangxi Province, a specimen that ticks all these boxes.  The fossils represent the partial, articulated remains of oviraptorosaur preserved sitting on a clutch of eggs in a brooding position.  Such fossils have been found before, but uniquely these 70 million-year-old remains include fossils of baby dinosaurs preserved inside the eggs, the first time this has been recorded in the non-avian dinosaur fossil record.

Sitting Atop a Nest

The multinational team of researchers includes Dr Shundong Bi (Indiana University of Pennsylvania) and Xing Xu (Institute of Vertebrate Palaeontology – Beijing) along with Dr Matt Lamanna (Carnegie Museum of Natural History) and scientific illustrator Andrew McAfee.

Commenting on the significance of this discovery, Dr Bi stated:

“Dinosaurs preserved on their nests are rare, and so are fossil embryos.  This is the first time a non-avian dinosaur has been found, sitting on a nest of eggs that preserve embryos, in a single spectacular specimen.”

Fossils of brooding dinosaurs have been found before, perhaps the most famous is “Big Mamma” the fossilised remains of an adult Citipati osmolskae (also an oviraptorid) on display at the American Museum of Natural History (New York).

Oviraptorids – Very Bird-like Dinosaurs

The Chinese fossil material has been assigned to the Oviraptoridae, although Everything Dinosaur are not aware of any new taxon being announced.  Oviraptorid dinosaurs are mainly associated with Asia, but the closely related Caenagnathidae are also known from North America.  The bones of these dinosaurs are very bird-like and they do belong to a great linage of theropods that are related to modern birds (the Maniraptora).

The specimen represents an incomplete, articulated skeleton of a large, (presumably adult) oviraptorid crouched in a bird-like brooding posture over a clutch of at least twenty-four eggs.  The adult appears to have perished whilst brooding the clutch.  The researchers identified the preserved remains of seven unhatched dinosaurs entombed inside the eggs.  The late stage of development of the embryos suggests that, just like modern birds, oviraptorids brooded their eggs, rather than simply guarding them as observed in extant crocodilians.

A Caring Parent

Dr Lamanna explained:

“This kind of discovery, in essence, fossilised behaviour, is the rarest of the rare in dinosaurs.  Though a few adult oviraptorids have been found on nests of their eggs before, no embryos have ever been found inside those eggs.  In the new specimen, the babies were almost ready to hatch, which tells us beyond a doubt that this oviraptorid had tended its nest for quite a long time.  This dinosaur was a caring parent that ultimately gave its life while nurturing its young.”

As part of their research, the scientists conducted an oxygen isotope study that demonstrated that the eggs were incubated at high bird-like temperatures, further evidence to support the idea that the adult died whilst brooding its clutch of eggs.  Analysis of the tiny baby dinosaur bones preserved inside their eggs indicate that some babies were more fully developed than others, this suggests that the eggs might have hatched at different intervals, a hatching strategy known as asynchronous hatching.  This strategy is found in many types of birds today such as Shoebill storks and numerous species of birds of prey such as raptors and owls.

Oviraptorids – Evidence that they were Caring Parents

Asynchronous hatching appears to have evolved independently in oviraptorids and modern avians.

The Evolutionary Benefits of Asynchronous Hatching

If the eggs of oviraptorids did hatch at different intervals, then this too can provide an insight into the behaviour of these Late Cretaceous dinosaurs.  Biologists have identified a number of reasons why some kinds of bird alive today have evolved asynchronous hatching.

The evolutionary benefits of asynchronous hatching:

  • To reduce the losses from predators due to the whole brood not being present in the nest at the same time.
  • The younger animals are a back-up plan in case earlier hatched animals die.
  • When food resources are scarce the adults can dedicate the bulk of these scarce resources to the older babies and let the younger siblings perish.
  • Reduces the demands on the parents as they do not have to care for all the babies at the same time.

Gastroliths Identified

The researchers also noted the presence of gastroliths (stomach stones).  A cluster of tiny pebbles had accumulated in the body cavity of the adult dinosaur.  Gastroliths are associated with many different types of dinosaur, but this is the first time that undoubted gastroliths have been found in an oviraptorid.  As such, these stones may provide new insights into the diets of these very bird-like dinosaurs.

Dr Xu concluded:

“It’s extraordinary to think how much biological information is captured in just this single fossil.  We’re going to be learning from this specimen for many years to come.”

PNSO Domingo the Carnotaurus Model

By | January 5th, 2021|Adobe CS5, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|0 Comments

PNSO Domingo the Carnotaurus Model

Having announced the introduction of a replica of the giant South American theropod Carnotaurus (C. sastrei), on their various social media platforms, Everything Dinosaur have dedicated a blog post to this new for 2021 PNSO dinosaur model.  This provides the UK-based Everything Dinosaur the opportunity to post up some more images of this eagerly anticipated dinosaur, a figure that will be in stock later this year, perhaps in just a few weeks.

Domingo the PNSO Carnotaurus

It is appropriate that the PNSO Carnotaurus (number 36 in the PNSO prehistoric animal models that accompany your growth series), has been given a Latin name (Domingo).  Fossils of this famous abelisaurid are known from southern Argentina.  Indeed, the majority of the abelisauroids described to date herald from the southern hemisphere (the ancient landmass of Gondwana).

Model Measurements

The PNSO Carnotaurus figure measures around 23.5 cm in length.  The height of those prominent head crests, the helped to give this dinosaur its name (Carnotaurus means meat-eating bull), are around 11.5 cm off the ground.  Although PNSO do not declare a scale for their mid-size range of dinosaurs, Everything Dinosaur team members estimate that this new for 2021 figure is in around 1/32th scale.

Early Dinosaur’s Brain Reveals New Insights into Sauropodomorpha

By | January 4th, 2021|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

The Brain of Thecodontosaurus

Analysis of the brain and inner ear of the Late Triassic basal Sauropodomorpha Thecodontosaurus (T. antiquus), reveals that it may have been bipedal, able to hold a steady gaze whilst running and possibly predatory.  These are some of the conclusions drawn by researchers from the University of Bristol and the Oxford University Museum of Natural History in a new study published in the Zoological Journal of the Linnean Society.

The Research Team Used CT-scans and 3-D Modelling to Construct the Brain and Inner Ear of Thecodontosaurus

Named in 1836 (it was only the fourth dinosaur to be scientifically described), Thecodontosaurus is regarded as a basal member of the lizard-hipped Sauropodomorpha, a clade of dinosaurs that includes Brontosaurus, Brachiosaurus, Diplodocus and Argentinosaurus.  Thecodontosaurus was much smaller than its illustrious Jurassic and Cretaceous descendants.  It was approximately two metres long, more than half its body length was made up by its long, thin tail and it was lightly built with most palaeontologists estimating that it weighed around 20-25 kilograms, about as heavy as a border collie.

As an early member of the lineage of long-necked dinosaurs, a study of the fossilised remains of Thecodontosaurus can provide palaeontologists with a better understanding of the evolutionary history of the Sauropodomorpha.

Three-dimensional Modelling Techniques

Research, led by the University of Bristol, used advanced imaging and 3-D modelling techniques to digitally rebuild the brain of Thecodontosaurus.  The scientists suggest that Thecodontosaurus could have eaten meat, although the substantial part of its diet was plant matter, its brain morphology indicates that this little dinosaur had a good sense of balance and that it was agile, traits that may have helped it supplement its vegetarian diet with the occasional meal of captured prey.

Lead author of the study, Antonio Ballell stated:

“Our analysis of Thecodontosaurus’ brain uncovered many fascinating features, some of which were quite surprising.  Whereas its later relatives moved around ponderously on all fours, our findings suggest this species may have walked on two legs and been occasionally carnivorous.”

The research team was able to deploy imaging software to extract new information from the fossils in a non-destructive manner.  Numerous three-dimensional models were generated from CT scans by digitally extracting the bone from the rock, identifying and classifying anatomical details about the brain and the inner ear which were previously unknown in this taxon.

PhD student Antonio explained the basis of the research:

“Even though the actual brain is long gone, the software allows us to recreate brain and inner ear shape via the dimensions of the cavities left behind.  The braincase of Thecodontosaurus is beautifully preserved so we compared it to other dinosaurs, identifying common features and some that are specific to Thecodontosaurus.  Its brain cast even showed the detail of the floccular lobes, located at the back of the brain, which are important for balance.  Their large size indicate it was bipedal.  This structure is also associated with the control of balance and eye and neck movements, suggesting Thecodontosaurus was relatively agile and could keep a stable gaze while moving fast.”

The Diet of Thecodontosaurus

The diet of Thecodontosaurus, nicknamed the “Bristol dinosaur” as a result of its association with the city, remains uncertain, although this new study suggests that it may have been omnivorous.

Antonio added:

“Our analysis showed parts of the brain associated with keeping the head stable and eyes and gaze steady during movement were well-developed.  This could also mean Thecodontosaurus could occasionally catch prey, although its tooth morphology suggests plants were the main component of its diet.  It’s possible it adopted omnivorous habits.”

The researchers were also able to reconstruct the inner ears, allowing them estimate how well it could hear compared to other dinosaurs.  Its hearing frequency was relatively high, potentially inferring some sort of social complexity, an ability to recognise varied squeaks and honks from different animals.

Comparing Thecodontosaurus to Other Members of the Sauropodomorpha

The application of these technologies enabled the research team to compare the brain and inner ear of Thecodontosaurus to Saturnalia tupiniquim – an earlier basal sauropodomorph which roamed the southern hemisphere around twenty-five million years before Thecodontosaurus evolved.  Comparisons were also carried out between Plateosaurus, which is also known from the Late Triassic and the much later sauropod Spinophorosaurus (S. nigerensis) from the Middle Jurassic.

Professor Mike Benton, study co-author, said:

“It’s great to see how new technologies are allowing us to find out even more about how this little dinosaur lived more than 200 million years ago.”

The distinguished professor added:

“We began working on Thecodontosaurus in 1990, and it is the emblem of the Bristol Dinosaur Project.  We’re very fortunate to have so many well-preserved fossils of such an important dinosaur here in Bristol.  This has helped us understand many aspects of the biology of Thecodontosaurus, but there are still many questions about this species yet to be explored.”

A Trio of Rebor Oddities G-2016 Embryos

Time to start the New Year (2021) with a bang!  At midnight on the 31st December, Everything Dinosaur made the three new Rebor Oddities (Rebor Oddities Specimens: G-2016 Embryos), available for pre-order.  These innovative, science-fiction/fantasy pieces have already attracted a lot of interest from model collectors and dinosaur fans.  In a co-ordinated post with Rebor, customers of Everything Dinosaur are able to guarantee themselves one of these figures.

Rebor Oddities Specimens

The Rebor Oddities sub-brand has introduced to collectors a wide variety of innovative items.  The first to be introduced was the “Fossil Studies” Tylosaurus proriger skeleton incorporated within its own light-up display base.  This figure was swiftly followed by the beautiful “Chickenosaurus” embryo model.  Recently a trio of museum quality dinosaur fossil skulls have been introduced and followers of Everything Dinosaur on social media will know that later on this year the Compsognathus longipes preserved dissection specimens will be coming into stock.

Limited Numbers Available

In a statement put out by Rebor on social media, they have explained that pre-ordering will only be available for a few days.  Rebor went onto add that all three variants (Bakelite, Epoxide and Resinite), are extremely limited due to the high manufacturing defect rates, so a restricted number have been produced.  It is not known at this stage whether or not there will be another production run in the future.

Model Measurements

Each carefully crafted figure measures approximately 18.5 cm long.  They stand a fraction over 10.5 cm tall and the block which holds the embryo model is 3 cm deep.  Each of these clever replicas helps to showcase the innovative approach taken by Rebor.  They will provide a talking point and a highlight within a collection.

Everything Dinosaur estimates that each model will be available to send out to customers in late March.

Favourite Blog Posts of 2020 (Part 2)

Everything Dinosaur team members conclude their review of their favourite blog articles of 2020 by looking at articles and news stories that were posted up between July and December.  With the best part of 180 posts to choose from selecting our favourite six for this period was quite tricky.  The ones we have selected demonstrate the broad range of topics we cover on the Everything Dinosaur weblog.

To view our earlier article about our favourite posts in the first half of the year: Favourite Blog Posts of 2020 (Part 1).

July – “Lizard Born of Fire”

We might have been in the middle of a global pandemic but Everything Dinosaur team members kept up their blogging reporting upon tiny theropod eggs from Japan, a revision of Dilophosaurus and a number of new dinosaurs.  Our favourite post of the month concerned the scientific description of Aratasaurus museunacionali, a basal member of the Coelurosauria from Brazil.  The genus name translates as “lizard born of fire”, a reference to the terrible fire that ripped through the National Museum of Brazil where the fossil specimen was kept.

August – Oculudentavis khaungraae Not a Stem Bird

The controversy over the naming of the smallest dinosaur based on a skull preserved in amber from northern Myanmar rumbled on.  In August, a paper was published that refuted claims that the tiny skull of the animal named Oculudentavis khaungraae was that of an archosaur.  A month earlier (July 2020), the original scientific paper describing this remarkable fossil was retracted.

September: Doctor Who Meets a Trilobite

The Oxford University Museum of Natural History celebrated its 160th birthday, the Monsters of the Deep exhibition opened in the midst of the chaos caused by COVID-19 and Euparkeria got a makeover. Our favourite post of September concerned a new species of trilobite (Gravicalymene bakeri) from Tasmanian that was named after Doctor Who actor Tom Baker.

October – It’s a Dog’s Life

In October we reported on the mapping of the genome of the Scimitar-toothed cat Homotherium latidens, discussed a new species of mosasaur from Morocco and the diet of pterosaurs, but our favourite article concerned the research into ancient dog DNA.  The study suggested that the diversity observed between dogs in different parts of the world today originated when all of mankind were hunters and gatherers.

November – Dinosaurs from the Emerald Isle

In November, Everything Dinosaur celebrated publishing its 5,000 blog post, discussed Kholumolumo a dinosaur from an African rubbish dump, looked at seal evolution and got to grips with the earliest Paranthropus robustus skull described to date.

Our favourite post concerned the first dinosaur remains reported from Ireland, not just one dinosaur but two!

December – Thalassodraco etchesi Swims into View

As the year closed, in the final month of 2020 we looked at how interactive “I-books” were helping to explain archaeology, examined a very flashy new dinosaur (U. jubatus), the first sauropod dinosaur from Switzerland (Amanzia greppini) and studied Parasaurolophus pathology.

Our favourite post concerned the establishment of a new species of Late Jurassic ichthyosaur after the discovery of fossil bones by the wonderful Dr Steve Etches MBE, the founder of the amazing Etches Collection museum in Dorset.

Favourite Blog Posts of 2020 (Part 1)

At Everything Dinosaur, we try and post up an article on this blog site every single day.  This can be quite a challenge considering all our other activities and projects.  However, as a result of our work on this weblog we have managed to compile a huge amount of information, articles and features chronicling (for the most part), advances in the Earth sciences and new fossil discoveries along with research into the Dinosauria.

This year, Everything Dinosaur’s blog has passed the 5,000 articles benchmark.  Here is a selection of our own favourite news stories that we have covered in the first six months of 2020 (January to June).

January – A New Allosaurus Taxon

In January, a new species of North American Allosaurus was added to the pantheon of dinosaurs known from the famous Morrison Formation of the western United States.  Allosaurus jimmadseni honours the sadly departed James H. Madsen Jr. Utah’s inaugural state palaeontologist.  The famous Allosaurus specimen MOR 693 “Big Al” was reassigned to this new species.

February – The “Father of Argentinian Palaeontology” – José Bonaparte

On the 18th February José Bonaparte, regarded by many as the most influential vertebrate palaeontologist of the 20th Century passed away.  Respected and admired, José helped to develop and train a whole new generation of Earth scientists.  He was also responsible for naming and describing a large number of new dinosaurs including Abelisaurus, hence our illustration of that South American theropod (below).

March – Telling the Time Back in the Cretaceous

As the COVID-19 pandemic took hold, team members at Everything Dinosaur were distracted by some remarkable research undertaken by scientists from the University of Ghent and the Vrije Universiteit Brussel.

A study of the growth rings preserved on the fossilised shells of Cretaceous bivalves permitted the researchers to calculate that 70 million years ago, the day length was approximately thirty minutes shorter and a year on Earth was around a week longer than it is today.

April – Homo erectus at Home in Africa

The remarkable Drimolen fossil hominin site in South Africa, provided palaeoanthropologists with likely confirmation that the hominin H. erectus did indeed evolve in Africa and not Asia.  A carefully and painstakingly reconstructed fossil skull (DNH 134), found in this area – regarded as the “Cradle of Humankind”, suggests that Homo erectus existed some 100,000 to 200,000 years earlier than previously realised.

We still have a lot to learn about our own evolution.

May – Lots of Pterosaurs

A jawbone found on the Isle of Wight was identified as a new species of tapejarid pterosaur.  The flying reptile, named Wightia declivirostris which translates as “slanting beak from the Isle of Wight” was one of several new pterosaur species described in 2020.

We have a lot more to learn about the Pterosauria too.

June – Fossilised Stick – Provides a Surprise

A fossil discovered more than fifty years ago and regarded as little more than a “fossilised stick” has proved to be a new species of Late Devonian plant and it will help scientists to better understand the flora of the ancient landmass of Gondwana.

The specimen was found by amateur geologist John Irving whilst exploring the banks of the Manilla River in Barraba (New South Wales, Australia).  A study in the open-access journal PeerJ identifies the newly named Keraphyton mawsoniae and proposes that it has a similar structure to primitive horsetails and ferns.  The fossil which looks so unremarkable on the outside, once studied in cross-section, has provided a unique window into the plant life on Earth around 360 million years ago.

Merry Christmas from Everything Dinosaur

From all of us to all of you, we would just like to wish everyone a very happy Christmas.  This special day seems to come round even quicker each year.  Team members have been so busy wrapping parcels for customers that we have hardly had time to wrap our own presents and gifts.

Santaroarus Wishes Everyone a Very Merry Christmas

Lots of Exciting Plans

Here’s hoping that all our blog readers and social media followers have a Happy Christmas and a Peaceful and Prosperous New Year.  We have lots of exciting plans for 2021, but before we get there we have perhaps the worst job of the year ahead of us – stock take.  Between now and New Year, we will all be in the warehouse counting the stock, with something like 1,000 product lines it is going to be a “mammoth” task!

We will also be rolling out some changes to our website, we will be able to offer our customers in Europe a fast, fully tracked postal service with all deliveries duty paid (DDP).  No hidden charges, no carding fees, no administration costs for our customers, just the usual 5-star customer service you have come to expect from Everything Dinosaur.  We might even be nominated for another customer service award as well…

Our stock take might be arduous but we will take it in our stride.  Still, I’m sure someone will bring in some mince pies and Christmas cake and this will keep us going.

On behalf of all the team members at Everything Dinosaur have a Happy Christmas.
