The Suskityrannus hazelae drawing will be converted into a scale drawing. This illustration will be incorporated into a fact sheet on this small theropod dinosaur.

The next shipment of Beasts of the Mesozoic articulated figures is expected to dock at Felixstowe at the end of July. The shipment will contain other, new Wave 2 theropods such as Proceratosaurus, Qianzhousaurus and Lythronax.

To view the Beasts of the Mesozoic figures available from Everything Dinosaur: Beasts of the Mesozoic Articulated Prehistoric Animal Figures.

Suskityrannus hazelae

Named and described in 2019 (Nesbitt et al), this dinosaur is known from two fossil specimens. The fossils come from the Moreno Hill Formation of the Zuni Basin in New Mexico. The deposits associated with the tyrannosauroid fossils have been dated to around 92 million years ago.

To read the Everything Dinosaur blog post that covered the formal scientific description of S. hazelae: Suskityrannus hazelae A Late Cretaceous Tyrannosauroid from New Mexico.

Although known from fossil material representing juveniles, palaeontologists were able to make some startling conclusions. Suskityrannus hazelae, had the same general body shape and feet adapted to running (arctometatarsalian feet), as the later, much larger tyrannosaurs such as Albertosaurus, Gorgosaurus and Tyrannosaurus rex.

The Schleich Quetzalcoatlus figure has jointed wings. The model can be displayed flying or in a resting pose.

Schleich has a long history of producing Quetzalcoatlus figures. Quetzalcoatlus featured in the original Schleich “Saurus” model series and also in the smaller Schleich dinosaurs range. This is the first Schleich pterosaur to be produced with articulated wings.

The model has a brightly coloured head. Palaeontologists think that pterosaurs had excellent colour vision.

A spokesperson from Everything Dinosaur commented:

“The head of the Quetzalcoatlus is a striking combination of crimson and purple. The colour scheme chosen by the design team at Schleich is quite inspired.”

The spokesperson added:

“The novel, folded wings provide plenty of options for creative, imaginative play.”

The Woolly Rhinoceros (Coelodonta antiquitatis)

It is thought that this ancient rhinoceros evolved in Asia. During the Pleistocene Epoch it had an extensive range.

To read an Everything Dinosaur blog post from 2011, about the origins of the Coelodonta genus: The Origins of the Woolly Rhino.

Fossils of Coelodonta antiquitatis have been found in the London area (Thames River gravels). The scientific name translates as “ancient hollow tooth”. The name derives from the animal’s teeth. Molars associated with this grazer of grasses and sedge have a distinctive cavity.

The Mojo Fun Woolly Rhinoceros model measures around 19 cm in length. Everything Dinosaur team members estimate the head height to be around 7 cm.

Woolly Rhino Extinction

The last of the Woolly Rhinos are believed to have persisted in Siberia. The genus becoming extinct around 13,000 to 14,000 years ago. A research paper published in 2021 (Wang et al), postulated that some Woolly Rhinos could have survived into the Holocene, with the last of their kind dying out around 9,800 years ago. The conclusions of the study, which was based on the dating of environmental DNA, have been challenged. The environmental DNA could have originated from older sediments and subsequently redeposited into much younger strata.

The picture (above) shows the first of these two figures to be unpacked this morning. A shipment of Papo models arrived including the Papo Archaeopteryx and the Woolly Rhino.

A spokesperson from Everything Dinosaur stated:

“It is great to see these old friends again. We know that many collectors missed out on these two models when they were originally launched. These model fans have the opportunity to complete their Papo collections.”

To view the range of Papo prehistoric animal models in stock at Everything Dinosaur: Papo Dinosaurs and Prehistoric Animal Figures.

The Papo Woolly Rhinoceros Model

The Papo Woolly Rhinoceros model was introduced in 2013. It was retired a few years later. The figure has proved popular with collectors. Numerous Woolly Rhino fossils have been found in France and Papo were keen to introduce models of animals reflected in the country’s own extensive fossil record. The Woolly Rhinoceros had a large, keeled front horn. This horn and the model’s shape reflected fossil evidence and the prehistoric drawings found in French caves.

Papo Archaeopteryx

The Papo “Urvogel” or Archaeopteryx was first introduced into the “Les Dinosaures” range back in 2014. This colourful theropod model was withdrawn in 2019. One of the ways in which manufacturers can engage with their customers is by reintroducing old favourites that had gone out of production. It also provides the manufacturer with a low-cost model. No mould making costs or development costs are associated with a reintroduced figure.

A Wonderful Palaeotherium Welcomed Back at Crystal Palace

By |2024-01-02T20:39:15+00:00July 2nd, 2023|Categories: Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Photos|0 Comments

A Victorian-era statue of a Palaeotherium magnum, an ancient mammal distantly related to horses has been rebuilt and installed at Crystal Palace. The original sculpture, designed by Benjamin Waterhouse Hawkins, was lost in the 1960s. Thanks to a dedicated team of historians, palaeontologists and artists Palaeotherium has returned to the famous Crystal Palace Dinosaurs site.

The Crystal Palace Dinosaurs Site

The Crystal Palace Dinosaurs have Grade 1 listed status. The collection consists of around thirty figures and approximately forty geological displays. They were created in the 1850s and represent the world’s first attempt to depict life-size prehistoric animals.

Commenting on the significance of the site, evolutionary biologist at the Natural History Museum and Chair of the Friends of the Crystal Palace Dinosaurs, Elinor Michel stated:

“The sculptures are of huge historic and scientific importance. The display first opened twenty-eight years before the London Natural History Museum and was the first-time models of extinct creatures had been used to engage people with science and geological time. For many visitors, this was their first introduction to the idea of lost worlds of animals and environments that no longer exist.”

Victorian-era Sculptures of Prehistoric Animals

Crystal Palace might be famous for its dinosaur sculptures, but only four of the statues represent members of the Dinosauria. The other figures represent marine reptiles, pterosaurs, crocodilians, amphibians and prehistoric mammals.

The building of a life-size Palaeotherium magnum was a task taken up by Britain’s leading palaeo artist and chum of Everything Dinosaur Bob Nicholls. Friends of the Crystal Palace Dinosaurs, staff from the Natural History Museum and researchers from the University of Portsmouth supervised the project.

This is the first attempt in twenty years to replace a lost sculpture at Crystal Palace. The resurrection of Palaeotherium emphasises the importance of the work to document the changes that have taken place within the grounds.

Palaeotherium magnum

Professor Adrian Lister (London Natural History Museum) commented:

“Palaeotherium magnum is the largest among a group of five mammal species represented in the Park that lived in the Eocene some 44.5 to 33.5 million years ago when Britain was clothed in tropical forest. The size of a small, chunky pony, it was a browsing mammal some 2 metres long and 1.3 metres high.”

Palaeotherium Project is Part of a Wider Initiative

The Palaeotherium project is part of a wider initiative to revive and conserve the Crystal Palace Dinosaurs site. Friends of Crystal Palace Dinosaurs, Historic England, the new Crystal Palace Park Trust and Bromley Council have been working together to develop a plan to protect the site. The resurrection of Palaeotherium magnum highlights a more optimistic, entertaining and enlightening future for one of the UK’s most iconic greenspaces.

The Evolution of Homo sapiens

Sergio Almécija has been fascinated by the multiple narratives surrounding our origins, behaviours and the prospects for our future. He has taken an innovative approach to his subject. A list of questions was compiled and then he contacted leading academics and researchers and recorded their thoughts.

Some of the questions included are:

  • Which discovery, research study, or book would you highlight as a “game changer” in the way we look at our own evolution? How did it influence your career or life?
  • If you had a one-shot round trip in a time machine, to which specific time period—past or future—would you go and why?
  • What will be shaping human evolution in the future? What will humans look like in 100, 100,000, or 1 million years?
Perspectives on our evolution.

Iani smithi – A New Dinosaur is Described

By |2024-01-02T20:28:09+00:00June 30th, 2023|Categories: Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

A newly discovered ornithopod dinosaur is helping to document faunal turnover in the early Late Cretaceous of North America. The dinosaur, named Iani smithi has been classified as a basal member of the Rhabdodontomorpha. This type of dinosaur is distantly related to the duck-billed dinosaurs (Hadrosauridae), which were to become extremely common by the Late Cretaceous.

The plant-eating I. smithi lived when the Earth was undergoing an intensive period of climate change. Global populations of dinosaurs were changing. Many long-established clades were dying out, being replaced with different types of dinosaur that were to dominate terrestrial environments until the end of the Mesozoic.

Iani smithi

Described from fossils excavated in 2014 from a quarry within the lower Mussentuchit Member of the Cedar Mountain Formation (Utah), the single specimen is thought to represent a juvenile. The fossil material consists of a disarticulated skull, vertebrae, limb elements, parts of the pectoral and pelvic girdles and ribs.

Researchers estimate that Iani lived approximately 99 million years ago (Cenomanian faunal stage of the Late Cretaceous). The Earth was rapidly warming due to increased concentrations of carbon dioxide in the atmosphere. Sea levels were rising and this dramatic period of climate change, known as the Cretaceous Thermal Maximum (KTM), led to extensive faunal turnover.

In North America, sauropods became rarer and eventually extinct (probably). Smaller ornithischian dinosaur clades began to dominate terrestrial environments. Spinosaurids and carcharodontosaurids were in decline. These theropods were eventually replaced by tyrannosaurs and abelisaurids.

This dramatic faunal turnover is reflected in the dinosaur’s name. The genus honours Janus – the two-faced Roman god of change.

The species name honours Joshua Aaron Smith. It is in recognition of his contribution to the discovery and conservation of paleontological resources in Utah.

A Rarity in North America

Iani smithi will help palaeontologists to better understand the transition of the Ornithopoda from Early Cretaceous groups to those bird-hipped dinosaurs that dominated Late Cretaceous terrestrial environments. Early rhabdodontomorphs such as Iani are exceptionally rare in the North American fossil record.

Corresponding author of the scientific paper, Lindsay Zanno (North Carolina State University) commented:

“Finding Iani was a streak of luck. We knew something like it lived in this ecosystem because isolated teeth had been collected here and there, but we weren’t expecting to stumble upon such a beautiful skeleton, especially from this time in Earth’s history. Having a nearly complete skull was invaluable for piecing the story together.”

A Phylogenetic Assessment of Iani smithi

Zanno and her team used the well-preserved skeleton to analyse the evolutionary relationships of Iani and were surprised, and at first sceptical of their findings.

Associate research professor Lindsay Zanno explained:

“We recovered Iani as an early rhabdodontomorph, a lineage of ornithopods known almost exclusively from Europe. Recently, palaeontologists proposed that another North American dinosaur, Tenontosaurus – which was as common as cattle in the Early Cretaceous – belongs to this group, as well as some Australian critters. If Iani holds up as a rhabdodontomorph, it raises a lot of cool questions.”

The research team speculate that Iani could be the last of its line. Studying this fossil specimen, in the context of environmental and biodiversity changes during the Cretaceous will provide insight into the history of our planet.

Lindsay Zanno added:

“Iani may be the last surviving member of a lineage of dinosaurs that once thrived here in North America but were eventually supplanted by duckbill dinosaurs. Iani was alive during this transition, so this dinosaur really does symbolise a changing planet.”

A Beautiful Mapusaurus Fossil Skull

By |2024-01-02T20:28:25+00:00June 29th, 2023|Categories: Adobe CS5, Dinosaur Fans, Main Page, Photos/Pictures of Fossils|0 Comments

Amongst the many exhibits at the “Titanosaur: Life as the Biggest Dinosaur” exhibition is a theropod replica skull. Team members visited the exhibition and marvelled at the dinosaur’s model skull. If we recall correctly, it was a replica of a Mapusaurus fossil skull. The “Titanosaur: Life as the Biggest Dinosaur” exhibition is currently at the London Natural History Museum.

Mapusaurus roseae

Mapusaurus (M. roseae), has been classified as a member of the Carcharodontosauridae family. More specifically, this huge theropod is regarded by many palaeontologists as a sister taxon to Giganotosaurus. As such, it has been classified in the tribe Giganotosaurini alongside Giganotosaurus carolinii.

The picture (above) shows how Mapusaurus models have changed over the last few years as more carcharodontosaurid fossils have been found. These models are all CollectA replicas.

To view the CollectA range of not-to-scale prehistoric animal models: CollectA Prehistoric Life Models.

Mapusaurus Fossil Skull

Palaeontologists know that large carcharodontosaurids coexisted with titanosaurs like Patagotitan (P. mayorum). It has been postulated that theropods did hunt titanosaurs. Perhaps carnivores mobbed sick, old or juvenile members of the herd. It is hard to imagine a single 13-metre-long carnivore being able to subdue an adult Patagotitan that measured more than 30 metres in length.

A carcharodontosaurid skull is included in the exhibit. We think this is a replica of the skull of Mapusaurus roseae. Mapusaurus is geologically younger than Patagotitan. The dating of volcanic ash layers associated with the Patagotitan deposits suggest that this dinosaur lived approximately 100 million years ago.

M. roseae fossils are associated with the Huincul Formation, these are younger strata than the rocks associated with Patagotitan fossil material. Mapusaurus lived approximately 96-94 million years ago.

To read Everything Dinosaur’s earlier blog post looking at a trio of carcharodontosaurid dinosaurs: A Trio of Carcharodontosaurids.

There is a carcharodontosaurid that comes from the same Member of the Cerro Barcino Formation as Patagotitan. This dinosaur is Tyrannotitan chubutensis, another giant member of the Giganotosaurini tribe. Tyrannotitan may have hunted and attacked Patagotitan.
