The New Rebor GrabNGo Tyrannosaurs are in Stock

By | June 12th, 2021|Adobe CS5, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products|0 Comments

The two new Rebor GrabNGo T. rex dinosaur models (Rebor GNG05 1:35 scale SA T. rex Type D and Rebor GNG04 1:35 scale SA T. rex Type C) are now in stock at Everything Dinosaur. These eagerly anticipated Tyrannosaurus rex models arrived at the Everything Dinosaur warehouse yesterday and they will be replacing the original GNG Rebor rexes that were introduced in 2020.

The models are the same sculpt but they have very different colour schemes. GNG04 is a dark green figure with subtle black banding, whilst GNG05 can be described as mainly brown-coloured but with prominent white markings on the head and neck. Each figure measures 40 cm in length and is supplied with a transparent support stand to permit Rebor to keep the well-crafted hind feet in proportion with the rest of the model.

The colouration of the Rebor GNG05 1:35 scale SA T. rex Type D, reminds team members at Everything Dinosaur of the Tyrannosaurus rexes that featured in the American documentary series “Dinosaur Revolution” that aired around ten years ago. In the four-part documentary series, the final episode featured the dinosaur dominated biota of the Hell Creek Formation of North America. Several T. rex dinosaurs were featured in this programme. If we recall correctly there were two male T. rexes, one was called “Jack Palance” and another called “Stumpy”. “Stumpy” had a deformed forearm as a result of a fight with the bigger “Jack Palance”, fortunately the Rebor GNG05 1:35 scale SA T. rex Type D has no such disability.

PNSO to Add a Tarbosaurus Dinosaur Model

By | June 11th, 2021|Adobe CS5, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|1 Comment

In a joint collaboration with PNSO, Everything Dinosaur is pleased to announce that a Tarbosaurus dinosaur model is being introduced into PNSO’s mid-size prehistoric animal model range. Say hello to Chuanzi the Tarbosaurus, the very latest addition to the ever-growing PNSO prehistoric animal portfolio.

This new dinosaur figure is likely to be available from Everything Dinosaur in the late summer of 2021.

Dinosaur fans and model collectors will be aware that PNSO have ramped up production considerably and numerous new figures have been announced since the end of 2020. Chuanzi the Tarbosaurus is the second member of the Tyrannosauroidea to be announced this year after Yinqi the Yutyrannus (April 2021). Eagle-eyed collectors will note that the Tarbosaurus figure is number 51 in this series, whilst Yinqi, which was announced earlier is number 52.

Tarbosaurus bataar

Named and described in 1955, Tarbosaurus (T. bataar) is one of the largest tyrannosaurids known. It is believed to have been slightly smaller than Tyrannosaurus rex, but closely related to the “tyrant lizard king”. Tarbosaurus measured around 12 metres in length and most body weight estimates suggest a figure of between 4,000 and 5,000 kilograms.

Model Measurements

Chuanzi the PNSO Tarbosaurus measures 31 cm in length and it has a head height of 11 cm. The recently introduced new Wilson the T. rex figure is slightly longer (34.5 cm long), so these two models can be displayed together to provide the viewer with a comparison between these closely related Late Cretaceous tyrannosaurs.

Available from Everything Dinosaur in the Summer (2021)

A spokesperson from Everything Dinosaur confirmed that they intended to stock this figure and that it should be available from them later this summer. They also stated that there were more prehistoric animal figures to be announced.

As with other theropod dinosaur models in the PNSO model range, this new Tarbosaurus will have an articulated lower jaw and it will be supplied with a transparent stand to help support the model.

A Highly Acclaimed Guidebook

“Fossil Collecting on the East Dorset Coast” is aimed at amateur as well as the more serious fossil hunter and it is required reading if you want to visit some of the more remote parts of the Dorset coast. Access to some of the locations can be tricky and the authors have ensured that plenty of useful information has been included such as advice about tide times, avoiding the dangers of rock falls (which can be frequent along this stretch of the coastline), along with details about accessing quarries and which ones require visitor permission.

This highly acclaimed guidebook is beautifully illustrated with lots of colour photographs not only showing fossil finds but also highlighting the stunning landscape and geology of this part of the southern coast of England.

Fossil collecting on the East Dorset Coast
The book is packed with beautiful photographs showing typical fossil finds at each location as well as stunning shots of the Dorset coast. Often typical fossil finds are shown against a backdrop of the magnificent scenery of this part of England’s southern coast.

Stunning Images of Fossils

The authors provide an introduction to the UNESCO World Heritage site known as the “Jurassic Coast” before outlining the Dorset fossil collecting code of conduct and focusing on the unique geology of east Dorset. The book is then sub-divided into different sections taking the reader on fossil hunting excursions starting at the majestic Bat’s Head and St. Oswald’s Bay in an easterly direction to Worbarrow Bay and Gad Cliff through to Peveril Point and Swanage. The final excursion visits the Studland Bay and the Hengistbury Head area. Each part of the book contains stunning images of the fossils associated with each location.

Studying Stegosaurs from the Arctic Circle

By | June 6th, 2021|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles, Photos/Pictures of Fossils|0 Comments

Earlier this spring, a team of researchers led by Pavel Skutschas (St Petersburg University, Russia), published a paper reporting on the study of 63 stegosaur teeth that had been found in Lower Cretaceous deposits in south-western Yakutia, located in eastern Siberia. Just like today, during the Early Cretaceous this part of Siberia was at a high latitude (palaeolatitude estimate of N 62°- 66.5°) and within the Arctic circle. The scientists conclude that these stegosaurs may have had some special adaptations to help them survive their harsh environment, such as a rapid tooth replacement rate to permit them to cope with a diet mainly consisting of conifer needles and branches.

Specimens ZIN PH 80/246 (A-D), ZIN PH 57/246 (E-H) in labial (A, E), lingual (B, F), occlusal (C, G) views, and interpretive drawings (D, H) in occlusal views showing the wear facets with scratches. Picture credit: Skutschas et al.

Stegosaurs Probably Present All Year

There has been much debate amongst palaeontologists as to whether large herbivorous dinosaurs such as stegosaurs were permanent residents of high latitude palaeoenvironments, or whether they migrated up to these latitudes in the summer to take advantage of the long periods of daylight. In the height of summer, there would have been around twenty-two hours of daylight at this latitude presumably providing very favourable conditions for plant growth.

The researchers, writing in the on-line, academic journal PLOS One report the discovery of smaller stegosaur teeth in the excavations, which took place in 2012 and then in the summer months from 2017-2019. As it is thought that the teeth represent a single species of stegosaur, this indicates that both adults and juveniles were present at this site.

Lead author Pavel Skutschas an Associate Professor in the Department of Vertebrate Zoology at St Petersburg University commented:

“We have found teeth of animals of different ages. This suggests that the polar stegosaurs are most likely to have been sedentary that they reproduced and raised offspring on the same territory all year round”.

A Diverse Prehistoric Fauna

The researchers from St Petersburg University worked together with colleagues from the Zoological Institute of the Russian Academy of Sciences, the Borissiak Paleontological Institute of the Russian Academy of Sciences, the University of Bonn (Germany) and the Diamond and Precious Metal Geology Institute of the Siberian Branch of the Russian Academy of Sciences to examine, excavate and sieve material from the Batylykh Formation, Sangar Series (Lower Cretaceous, Berriasian–Barremian faunal stage) along the banks of the Teete River in Suntar Ulus, Yakutia, Eastern Siberia. This location has yielded dinosaur fossils (including theropods as well as ornithischian dinosaurs), turtles, salamanders and early mammals.

The stegosaur teeth excavation site

Stegosaurian remains are the most abundant and consist of numerous isolated teeth, vertebrae, ribs, pelvic elements and occasional cranial material. The stegosaur teeth were all retrieved by screen washing and sieving samples. Most exhibit a high degree of wear and indicate that these animals fed on very abrasive plant material. In addition, study of the tiny scratches on the teeth suggest tooth on tooth contact and precise dental occlusion in the Teete stegosaurs. The microwear examined suggests that these animals had a more complex jaw movement to help them process food in their mouths, the tooth wear observed could not have occurred if these dinosaurs were only capable of moving their jaws up and down in a simple scissor-like action.

Picture credit: Skutschas et al.

Rapid Tooth Replacement

Under the microscope, the researchers made another surprising discovery. The Teete stegosaurs are characterised by their relatively short tooth formation time. The teeth were rapidly replaced and the replacement teeth were formed in a relatively short time (95 days). This might have been an adaptation to the particularly abrasive diet of these herbivores which probably fed on conifers. Furthermore, the scientists identified the presence of a “wavy enamel pattern” on the teeth. This type of enamel has also been found on the teeth of Psittacosaurus, a basal member of the horned dinosaurs (Ceratopsia) and within the Ornithopoda. The researchers conclude that this feature of teeth is a shared trait amongst bird-hipped dinosaurs. Whether it was present in the ancestor of the ornithischian dinosaurs or whether this histological feature is an example of convergent evolution in different types of plant-eating dinosaur is not known.

Helicoprion Scale Drawing

By | June 5th, 2021|Adobe CS5, Dinosaur and Prehistoric Animal Drawings, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Press Releases|0 Comments

As Everything Dinosaur team members prepare for the arrival of the new for 2021 PNSO Helicoprion model a scale drawing of this strange fish from the Permian has been commissioned. Haylee the Helicoprion model is due to be in stock at Everything Dinosaur later in the summer (2021).

Helicoprion bessonowi

Three species in the Helicoprion genus are currently assigned, each one being distinguished from the others by variations identified in the distinctive tooth whorl. The size of this predator remains uncertain, although based on the morphology of other smaller related fish, Helicoprion has been estimated to have been around 5 to 8 metres in length. In the Everything Dinosaur scale drawing that we have prepared, our image indicates that this strange fish grew to lengths of around 7.5 to 8 metres.

Haylee the Helicoprion

As with the other mid-size PNSO replicas, this stunning model has been given a nickname. The figure is called Haylee the Helicoprion, Everything Dinosaur team members are not sure why Haylee was chosen; however, it is certainly a welcome addition to the PNSO product portfolio and we are looking forward to stocking it later on this year (2021).

PNSO Haylee the Helicoprion model measurements
The model measures 21 cm in length and from the base of the tail fluke to the top of the dorsal fin of the Helicoprion is 7.5cm

Model Measurements

The model measures around 21 cm in length and although PNSO do not declare a scale for this range of prehistoric animal figures, team members estimate that if Helicoprion was around 8 metres in length then this model would be in approximately 1:38 scale or thereabouts.

A Pterosaur Dance Floor from China

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

Scientists writing in the academic journal “PeerJ” have reported the discovery of an extensive pterosaur trackway from the Lower Cretaceous Shengjinkou Formation in the Xinjiang Uygur Autonomous Region in north-western China. The trackway consists of 114 small pterosaur tracks (57 handprints and 57 footprints). Analysis of these trace fossils has led to the erection of a new pterosaur ichnospecies – Pteraichnus wuerhoensis, although the researchers speculate that these tracks could have been made by the dsungaripterid pterosaur Noripterus complicidens.

Pteraichnus pterosaur tracksite

A Complicated Trackway to Interpret

As 57 handprints (manus) and 57 footprints (pes) have been preserved on the same slab of finely-grained sandstone, the researchers confidently assert that the trackmaker was quadrupedal, but they can’t say for certain whether these prints were all produced at the same time. It is presumed that they would have been made over a short period of time on a muddy shoreline close to a large lake, as they would have needed to be covered by sediment quite quickly to permit their preservation. The lack of ripple marks or invertebrate trace fossils in the slab suggest that this surface was rapidly buried after only being exposed for a short period.

The handprints range in size from 1.9 cm long to 5.15 cm, whilst the feet impressions range in size from 2.68 cm to 5.71 cm. This suggests that the tracks were made by pterosaurs of different ages. This indicates that both adult and juvenile forms may have congregated at this location.

Gregarious Pterosaurs

The density of the Wuerho small pterosaur tracks was also remarked upon. The density is high, the assemblage would represent a density of tracks of around 365 per square metre. Generally, high densities of tracks (in excess of 100 per square metre), have often been cited as evidence of gregarious behaviour or high activity levels.

A detailed comparison with other pterosaur tracks suggests that these prints belong to the ichnogenus Pteraichnus, this is the tenth ichnospecies to be assigned to this ichnogenus. It being distinguished from the others by several traits, for example in these tracks the length of the toes on the foot are equal to the length of the metatarsal part of the foot. The ratio between the length of the toes and the rest of the foot is 1:1, this ratio is different from other reported pterosaur tracks assigned to the ichnogenus Pteraichnus.

Pteraichnus ichnospecies could be Noripterus complicidens
The foot of the dsungaripterid pterosaur Noripterus complicidens (left) with outline drawing of N. complicidens foot (middle) and interpretative drawing of a track made by a foot (right). The researchers infer that these tracks were probably made by N. complicidens. The length of the digital part of the foot (Di) is equal to the length of the metatarsal part of foot (Me). The ratio between the length of the toes and the rest of the foot is 1:1 this ratio is different from other reported pterosaur tracks assigned to the ichnogenus Pteraichnus and therefore supports the theory that these tracks represent a new ichnospecies. Picture credit: Li et al with additional notation by Everything Dinosaur.

Tracks Possibly Made by Noripterus complicidens

The researchers from the Chinese Academy of Sciences (Centre for Excellence in Life and Palaeoenvironment), postulate that the tracks may have been made by the dsungaripterid pterosaur Noripterus complicidens. To date only two genera of pterosaur have been identified from fossils found in the Shengjinkou Formation in north-western China. They are both members of the Dsungaripteridae family, a group of advanced pterodactyloid pterosaurs with robust, stout skulls and strong limbs. The two genera are Dsungaripterus (D. weii) and the slightly smaller Noripterus (N. complicidens). By comparing the tracks to the foot bone of Noripterus, the researchers concluded that these tracks were made by Noripterus, a pterosaur with a wingspan of approximately 2 metres that probably fed on shellfish, hence the congregation of pterosaur tracks at this site, although no feeding traces could be identified.

Praising Pinacosaurus

By | May 30th, 2021|Adobe CS5, Dinosaur Fans, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products|0 Comments

There have been so many new model announcements made by PNSO in the last few weeks that model collectors can be forgiven for overlooking some of the recently introduced figures from this Chinese manufacturer. Take for example, Bart the Pinacosaurus. Pinacosaurus (P. grangeri) might not be the most famous member of the Ankylosauridae family, but Pinacosaurus is well-known in China, it has featured in the illustrations of prehistoric life by Zhao Chuang and PNSO introduced a model of this armoured dinosaur in early 2021.

A wonderful model of an armoured dinosaur. The recently introduced Bart the Pinacosaurus.

Why Bart?

PNSO have given their prehistoric animals in their rapidly expanding mid-size model range nicknames. This is a trend that they have followed since their very first replicas came out. Team members are not sure whether there is actually any logic applied when it comes to naming their figures, after all, we have recently announced “Jeff” the Kronosaurus: PNSO to Add “Jeff” the Kronosaurus.

As for Bart, we don’t know why the Pinacosaurus figure was given this moniker, we thought that “Granger” would have been more suitable in honour of the American palaeontologist Walter Wallis Granger, who discovered the first fossils of Pinacosaurus in 1923.

The Pinacosaurus replica is beautifully sculpted and typifies the quality associated with this mid-size model line. Whilst working in the studio, we took the opportunity to take some more photographs of this dinosaur model, the colouration of which reminds us of the Mountain Devil lizard from Australia.

We were able to take several pictures of the figure, including in dorsal view so the chosen colour scheme could be clearly seen.

An Upside-Down Dinosaur

As well as dorsal views, we wanted to depict the underside of the figure, complete with that very important CE mark (conformité européenne). After all, to a discerning dinosaur model collector it matters what a dinosaur’s undercarriage looks like.

This month (May 2021), has seen yet another scientific paper published describing a new species of mosasaur from the Late Cretaceous of Morocco. The newly described Pluridens serpentis reminds us that these whale-sized animals were related to snakes and lizards (Squamata). It may have sensed its marine environment in a similar way to extant sea snakes.

The orbits (eye sockets), were disproportionately small when compared to other mosasaurs, it also had very sensitive jaws that were capable of helping it to make sense of its environment (as indicated by numerous neurovascular foramina on the premaxillae). It may have specialised in hunting prey in deep water, or in poorly lit habitats. Picture credit: Andrey Atuchin.

Morocco a Hot Bed of Late Cretaceous Mosasaurs

Mosasaurs were the last, great group of marine reptiles to evolve. They originated in the early Late Cretaceous and they were around for about 20 million years, a much shorter temporal range than other marine reptiles from the Mesozoic such as the ichthyosaurs and plesiosaurs. However, they were extremely successful and globally widespread with more than 40 different genera described.

The extensive phosphate beds of the Ouled Abdoun Basin in northern Morocco have proved to be a hot bed of mosasaur fossil remains. Thirteen mosasaur genera have been named and described from these Upper Cretaceous (Maastrichtian) deposits to date. For example, Everything Dinosaur wrote about the discovery of the specialised piscivore Gavialimimus almaghribensis in October 2020: Another New Species of Mosasaur from Morocco.

Based on Two Complete Skulls and Referred Jaw Material

Writing in the academic journal “Cretaceous Research”, scientists including Dr Nick Longrich (University of Bath), describe P. serpentis based on two complete skulls and referred jaw material. The skulls imply a total body length of around 6 to 8 metres, but the jaw material found indicates that Pluridens could have grown much larger, perhaps as big as 10 metres in length.

It had long, slender jaws lined with over a hundred tiny snake-like teeth which were well-adapted to grabbing small fish and squid. When compared to other mosasaurs, Pluridens had relatively small eyes, suggesting it had poor vision. It probably relied on other senses to understand its environment and to hunt. The upper snout (premaxilla), had dozens of openings for nerves (neurovascular foramina), hinting at the ability to hunt by sensing water movements and changes in pressure. These nerves may have been sensitive to tiny variations in water pressure, an adaptation seen in sea snakes.

Lead author of the study, Dr Longrich, (senior lecturer at the Milner Centre for Evolution, University of Bath), commented:

“Typically, when animals evolve small eyes, it’s because they’re relying more heavily on other senses. If it wasn’t using the eyes, then it’s very likely that it was using the tongue to hunt, like a snake. Many aquatic snakes and lizards – sea snakes and water monitors flick their forked tongues underwater, using chemical cues to track their prey. Mosasaurs would have resembled whales and dolphins, so it’s tempting to assume they lived like them. But they’re very different beasts – they’re huge lizards – so they probably acted like them.”

Thick, Robust and Heavy Jawbones

The researchers, who include scientists from the Natural History Museum of Sorbonne University (France), the University Cadi Ayyad in Marrakech and the OCP Group S. A. (both in Morocco), noted that the dentary (lower jaw bone) becomes massive and robust in the largest individuals, suggesting sexual selection and perhaps sexual dimorphism. In some species of extant beaked whales, the males use their jaws in combat (intraspecific combat). It is postulated that male Pluridens behaved in a similar way with the mandibles possibly functioning for combat as in modern beaked whales and some lizards such as Komodo dragons.

Pluridens serpentis

The newly described Pluridens serpentis lends weight to the theory that mosasaurs were continuing to specialise and diversify until the very end of the Cretaceous. It is the thirteenth species of mosasaur to be identified from Morocco and very probably not the last. Team members at Everything Dinosaur are looking forward to the publication of future scientific papers, once again highlighting the remarkable diversity of North African mosasaurs during the Maastrichtian faunal stage of the Cretaceous.

The scientific paper: “Pluridens serpentis, a new mosasaurid (Mosasauridae: Halisaurinae) from the Maastrichtian of Morocco and implications for mosasaur diversity” by Nicholas R. Longrich, Nathalie Bardet, Fatima Khaldoune, Oussama Khadiri Yazami and Nour-Eddine Jalil published in Cretaceous Research.
