The Woolly Mammoth could return by 2028 according to an article published in a UK tabloid paper. The sensational headline claims that the extinct prehistoric elephant could be resurrected. Advances in genetic engineering could mean that extinct creatures could be coming back.

Woolly Mammoth De-extinction

Everything Dinosaur has featured several stories about de-extinction on this blog. One of the most recent concerned genetic research to resurrect the Thylacine, otherwise known as the Tasmanian Tiger. As a marsupial the significant problem of having to find a surrogate mother can be bypassed.

To read the Thylacine article, which is based on a media release from the University of Melbourne: The De-extinction of the Thylacine.

There would be many additional barriers to the genetic engineering of a viable Woolly Mammoth embryo. It is true that astonishing and rapid developments in genetic engineering could in theory bring back long extinct creatures. The resurrection would be achieved through the manipulation of an organism’s genome. This would result in the creation of a population of animals that had characteristics of animals that have died out. We are sure the article would have mentioned dinosaurs, but a “Jurassic Park”, is not going to be created anytime soon.

In 2015, Everything Dinosaur reviewed a book which provided a guide to cloning a Mammoth.

To read our review of “How to Clone a Mammoth”:“How to Clone a Mammoth”- Book Review.

Cloning Prehistoric Elephants

The book was written by Beth Shapiro, an Associate Professor at the University of California, Santa Cruz. It looked at the selection criteria for a de-extinction candidate species. She explained the joys and perils of hunting for Woolly Mammoth fossils and highlighted some of the scientific obstacles associated with cloning. There are ethical and moral considerations too. Should we bring back and animal that went extinct thousands of years ago, or perhaps focus on conserving extant fauna and flora.

Whatever the advantages and disadvantages of this aspect of genetic engineering, we did not expect to see a tabloid newspaper covering this research on the front page. We are not sure about the headline “lovable boffins…”.

We look forward to reading about the re-introduction of prehistoric elephants in 2028.

The Wild Past Scutosaurus and Kotlassia Figures

Scutosaurus was a Late Permian pareiasaur. It was one of the largest terrestrial vertebrates of the Late Permian. Known from several near complete skeletons, it is thought that this herbivore weighed more than a 1,000 kilograms. It was coeval with Kotlassia. Formally named and described in 1921 (Vladimir Amalitsky) Kotlassia (K. prima) is thought to be a basal member of the Seymouriamorpha. It may have been semi-aquatic, part of a group of transitional forms evolving into fully terrestrial animals.

A spokesperson from Everything Dinosaur confirmed that these two figures will be supplied with fact sheets. The spokesperson added:

“We congratulate the team at Wild Past for their excellent and unusual prehistoric animal figures. It is not everyday that Permain prehistoric animals get put into the spotlight. The Tethyshadros pair and the Protoceratops model with nest have proved popular, we are sure Kotlassia and Scutosaurus will prove popular with collectors too.”

Dreadnoughtus schrani

This huge sauropod was formally described in 2014 (Lacovara et al). Fossils representing two individual animals were excavated from outcrops of the Cerro Fortaleza Formation in Santa Cruz Province, Patagonia. The discovery of well-preserved limb bones enabled the research team to use limb bone circumference calculations to estimate the body weight of this leviathan. At the time of publication, it was suggested that Dreadnoughtus could have weighed more than 59 tonnes. The specimen upon which this body mass estimate was based, was not fully grown.

A spokesperson from Everything Dinosaur confirmed that this new for 2024 CollectA figure would be in stock early in 2024. No arrival date had been confirmed at this time, but the figure could be in stock around March 2024.

New CollectA Models for 2024 – Part 3

By |2023-11-16T23:40:55+00:00November 17th, 2023|Adobe CS5, Dinosaur Fans, Everything Dinosaur News and Updates, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products, Press Releases|2 Comments

Today, we make the third announcement with regards to new CollectA prehistoric animal models for 2024. CollectA will introduce a 1:20 scale armoured dinosaur and a new set of mini-dinosaur figures.

  • CollectA mini sauropod model set.
  • CollectA Deluxe Polacanthus.

At this time, we are not sure as to when the CollectA mini-sauropod set will be available. The CollectA Polacanthus is due to be in stock at Everything Dinosaur in the middle of 2024 or thereabouts.

Team members will discuss the mini-sauropod set in detail in a future blog post. For the moment we will focus on the new for 2024 Polacanthus foxii figure.

CollectA Deluxe Polacanthus.
The new for 2024 CollectA Deluxe 1:20 scale Polacanthus figure.

If Polacanthus had a parascapular spine it was a splate. A splate being a spine raised on a plate of bone (combination of plate and spine). This has been located over the shoulder.

CollectA Deluxe Polacanthus

Polacanthus (P. foxii) was scientifically described in 1865. The fragmentary holotype (NHMUK PV R175) was excavated from Upper Wessex Formation strata on the Isle of Wight. Numerous other specimens have been assigned to this genus in the past. The polacanthids have undergone an extensive revision. Today, only the holotype material is assigned to P. foxii.

CollectA Deluxe Polacanthus.
The dermal armour of this member of the Ankylosauria clade has been carefully reconstructed on the figure. The arrangement of the spikes and bosses is largely speculative.

The animal has a triangular shaped head. It broadens out considerably towards the back of the skull. The head is more typical of an ankylosaur. The narrow skull seen in some life reconstructions has been abandoned in favour of a skull shape that reflects the known polacanthid body plan. The model has two cervical rings of armour on the neck. It may have had three rings, but the fossil record of this dinosaur is quite poor. Only two cervical rings can be demonstrated by the fossil material, so the model has just two cervical rings. The limb proportions seem appropriate and great care has been taken in the placement and orientation of the dermal armour.

CollectA Deluxe Polacanthus..
The Polacanthus figure shows countershading on the underside and the design team have moved away from the typical brown and rust red colouration associated with the Ankylosauria.

A Revision of the Wealden Group Armoured Dinosaurs

Work is continuing to revise and define the armoured dinosaur fossil material associated with the extensive Wealden Group. CollectA were keen to introduce a revised Polacanthus figure with a sacral shield. This new model is a considerable improvement on the CollectA Prehistoric Life Polacanthus which did not have a sacral shield.

In addition, CollectA wanted to introduce an updated figure as recent research has continued to define the genus and has led to the erection of new armoured dinosaur species. For example, earlier this year, a new Wealden Formation ankylosaur was named Vectipelta barretti.

To read about the discovery of Vectipelta: New Armoured Dinosaur Species Honours Natural History Museum Professor.

Although fossils assigned to Vectipelta were once thought to represent Polacanthus, studies have revealed that these two dinosaurs were not that closely related. In addition, Vectipelta could be as much as eight million years older than the holotype Polacanthus foxii material.

Model Measurements

The Polacanthus figure has a declared scale of 1:20. The CollectA Deluxe Polacanthus dinosaur model measures 27.5 cm in length and the tip of the beautiful tail is held 13 cm high in the air.

The model will be available from Everything Dinosaur in the middle of 2024.

The Dinosaur Display

The teaching team had been focusing on food chains. They had used the dinosaur term topic to help the children to understand what foods animals eat. The Reception class were keen to demonstrate their knowledge. The children eagerly pointed out which dinosaurs ate meat and which ones ate plants.

For inspirational dinosaur themed toys and games: Dinosaur Toys and Gifts.

As part of the varied term topic, the children had been making replicas of fossils. Some of these fossil replicas were on display in the classroom.

Praising the Children and the Teaching Team

The fossil replicas had been created by pressing dinosaur models into salt dough. These objects had been painted a variety of metallic colours. The children’s artworks certainly made a colourful dinosaur display in the classroom.

We tested the children’s understanding of food chains. Some of the more capable learners were happy to identify which dinosaurs may have been omnivorous.

A spokesperson from the UK-based mail order company commented:

“We remember visiting the school back in March 2019. At the time we remarked on the beautiful school displays. The children had enjoyed their prehistoric animal themed term topic. They were eager to highlight which parts of the dinosaur display that they had personally contributed to.”

Dreadnoughtus was scientifically described in 2014 (Lacovara et al). Although body mass estimates have been challenged it remains one of the largest terrestrial vertebrates known to science. The genus contains a single species D. schrani. Two skeletons were found, and between them about 45% of the total skeleton of this huge titanosaur has been documented and described.

Dreadnoughtus Video

The video will highlight some of the features on the prototype model. It will cover colour choice, the arrangement of the dermal armour and the inclusion of thumb claws. The narrator will ask what other sauropod figures would you like CollectA to make?

This video is one of a series of Everything Dinosaur YouTube videos that focus on the new model introductions from CollectA. The CollectA Deluxe Dreadnoughtus video review will be posted up on the Everything Dinosaur YouTube channel in a few days.

The Super Senses of Thescelosaurus

By |2023-11-11T06:24:16+00:00November 11th, 2023|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

A newly published scientific paper, examining the skull of a bird-hipped dinosaur (Thescelosaurus neglectus), suggests that this dinosaur had remarkable senses. CT scans of the skull suggest that this Late Cretaceous herbivore possessed a unique combination of traits and indicate that Thescelosaurus may have spent at least some of the time underground. The study is the first to link a specific suite of sensory abilities with dinosaur behaviour.

If you live alongside Tyrannosaurus rex, then having a burrow or den to hide in might prove to be an effective survival strategy.

Studying the Skull of “Willo”

The skull used in the study comes from “Willo”, which is part of the North Carolina Museum of Natural Sciences vertebrate collection. Thescelosaurus is a member of the Ornithischia. The genus was erected in 1913. It measured around four metres in length and weighed around 340 kilograms. That is about as heavy as a Jersey cow. In an ecosystem which included Triceratops, Edmontosaurus as well as T. rex, Thescelosaurus tends to be overlooked.

Thescelosaurus and super senses.
A newly published scientific paper which undertook a detailed analysis of the skull of a Thescelosaurus suggests that this relatively small, Late Cretaceous dinosaur may have lived underground.

Thescelosaurus neglectus – “Wonderful, Overlooked Lizard”

The binomial scientific name of this dinosaur translates as “wonderful, overlooked lizard”. However, undeterred by this dinosaur’s lack of sharp teeth, dermal armour, crests or horns – traits associated with some of its contemporaries, Dr David Button (Bristol University) began studying Thescelosaurus.

Dr Button built up a detailed, three-dimensional model of the skull using multiple CT scans. The brain and the inner ear were reconstructed. This allowed the researchers to determine the size of the brain and to build up a picture of the dinosaur’s senses.

Dr Button commented:

“We found that the olfactory bulbs – the regions of the brain that process smell – were very well developed in Thescelosaurus. They were relatively larger than those of any other dinosaur we know of so far, and similar to those of living alligators, which can smell a drop of blood from miles away.”

Dr Button added:

“Thescelosaurus may have used its similarly powerful sense of smell to instead find buried plant foods like roots and tubers. It also had an unusually well-developed sense of balance, helping it to pinpoint its body position in 3D space, another trait often found in burrowing animals.”

There is More to Thescelosaurus

Co-author of the paper, published in Scientific Reports, Dr Lindsay Zanno (North Carolina Museum of Natural Sciences), stated:

“The irony is that palaeontologists generally think of these animals as pretty boring. When we first looked at our results we thought, yeah, this animal is plain as toast. But then we took a big step back and realised there was something unique about the combination of Willo’s sensory strengths and weaknesses.”

Limited Hearing

The scientists calculated that the hearing range of Thescelosaurus neglectus was extremely limited. It could only hear about 15% of the frequencies humans can detect, and between 4% to 7% of what dogs and cats can hear. In particular, T. neglectus was bad at hearing high-pitched sounds.

Dr Zanno explained:

“We found that Thescelosaurus heard low frequency sounds best, and that the range of frequencies it could hear overlaps with T. rex. This doesn’t tell us they were adapted to hearing T. rex vocalise, but it certainly didn’t hurt them to know when a major predator was tooling about in the area. More interesting to us was the fact that these particular deficiencies are often associated with animals that spend time underground.”

However, the researchers discovered that this dinosaur did have an excellent sense of smell.

T. neglectus may not have been particularly clever, not even for a dinosaur. It may have had limited hearing, but it had powerful arms and legs, a superb sense of balance and spatial awareness coupled with a keen sense of smell. These are all typical characteristics found in extant vertebrates that spend time underground or engage in digging behaviours.

Dr Button summarised the study:

“While we can’t say definitively that these animals lived part of their lives underground, we know that their ancestors did. This fact, together with their unique combination of sensory abilities, strongly suggests T. neglectus engaged in similar behaviours.”

Thescelosaurus neglectus – Not a “Boring” Dinosaur

Dr Zanno concluded:

“We still don’t know the sensory abilities of most dinosaurs. That makes it difficult to link these traits to specific lifestyles with confidence, but it also means there are plenty of cool discoveries to come. The idea that there might have been dinosaurs living under the feet of T. rex and Triceratops is fascinating. No matter what, we now know for certain that T. neglectus isn’t boring.”
