New PNSO Albertosaurus Dinosaur Model Reviewed

By |2024-01-02T14:36:52+00:00September 29th, 2023|Adobe CS5, Dinosaur Fans, Everything Dinosaur Products, Main Page, Photos of Everything Dinosaur Products|0 Comments

Our thanks to dinosaur fan and model collector William who sent into Everything Dinosaur a review of the PNSO Albertosaurus. William wrote to Everything Dinosaur and explained how Albertosaurus was named and scientifically described. He commented that in 1905 Henry Fairfield Osborn had just presented his paper describing a new North American theropod Tyrannosaurus rex. The Albertosaurus genus was also erected in 1905.

The reviewer added:

“Almost as a footnote at the end of his paper, Osborn named Albertosaurus sarcophagus. Named in honour of the newly founded Canadian province of Alberta from which the type specimen was unearthed. Thus, we see the founding of the first two great houses of the Tyrannosauridae to the south the Tyrannosaurinae to the north the gracile Albertosaurinae.”

PNSO Albertosaurus Reviewed

In the email to Everything Dinosaur, the reviewer praised the PNSO Albertosaurus figure. It was stated that this was an amazing and highly detailed sculpt. The choice of colour scheme and the firm, articulated jaw were highlighted.

William commented:

“Finally, I own a truly accurate yet handsome Albertosaurus with that special PNSO touch we have come to love. From sculpt to skin texture all fused with the natural warm skin tones no need of garish colours. Finalising in the wonderful yet unique horned head with a firm articulated jaw. “Wally” is captured as in mid stride as in pursuit no boring or dull figures that are vaguely standing but glimpses of a living animals as in life never boring or static is what all models should portray LIFE!!!!. Thanks Everything Dinosaur.”

The First Dicraeosaurid from India

By |2023-10-02T10:53:30+01:00September 26th, 2023|Adobe CS5, Dinosaur and Prehistoric Animal News Stories, Dinosaur Fans, Main Page, Palaeontological articles|0 Comments

Scientists have described the first dicraeosaurid sauropod dinosaur known from India. The dinosaur, named Tharosaurus indicus roamed northwestern India during the Middle Jurassic. At around 167 million years old, Tharosaurus indicus represents the earliest diplodocoid dinosaur described to date. It lived at least ten million years earlier than famous North American diplodocids such as Apatosaurus and Diplodocus, to which it was distantly related.

Fragmentary Fossils from Rajasthan

The fragmentary and disarticulated fossils consisting of vertebra and a solitary rib are believed to represent a single animal. The fossils were excavated from shale deposits just north of the village of Jethwai in Rajasthan State. The area is hot and arid, and it is known as the Great Indian Desert or the Thar Desert. The genus name of this new dinosaur references the Thar Desert, in recognition of the location of the fossil finds. The specific name honours the country of origin – India.

The fossil material was excavated from a bedding plane located at the base of the Fort Member (Jaisalmer Formation) with represents an early to middle Bathonian faunal stage deposition.

The Dicraeosauridae

The dicraeosaurids are a clade of small-bodied diplodocoid sauropods classified by their distinctive vertebrae with long paired neural spines. They are both temporally and geographically dispersed with fossils found in Africa, South America as well as China and the USA. The discovery of Tharosaurus extends their temporal range from the Bathonian faunal stage of the Middle Jurassic to the Early Cretaceous.

New Insights into Sauropod Diversity

The research team suggest that Tharosaurus indicus is a relic of a sauropod lineage that originated in India and underwent rapid dispersal across the rest of Pangaea. Writing in the academic journal “Scientific Research”, the scientists conclude that this fossil discovery provides new insights into sauropod diversity. It also has important implications for the origin and dispersal of neosauropod dinosaurs.

Tracing the Origins of the Sauropoda

The Sauropoda is thought to have originated in the Late Triassic/Early Jurassic. The origin and radiation of the Neosauropoda and its major clades (Macronaria and the Diplodocoidea) remains contentious. Non-neosauropods were restricted to eastern Gondwana (Zimbabwe and India) and parts of Laurasia (China, Germany and Thailand) during the Late Triassic/Early Jurassic. This suggests that there were barriers preventing their dispersal to the Americas and the most southerly portions of Gondwana. Although preservation and sampling biases cannot be ruled out, neosauropods possibly appeared during the late Early or early Middle Jurassic. The geologically youngest forms being associated with the Americas and Asia.

Tharosaurus indicus – Helping to Clarify Neosauropoda Evolution

Tharosaurus indicus is among the earlier-diverging dicraeosaurid dinosaurs, and its stratigraphic age (Bathonian) makes it the earliest known diplodocoid dinosaur globally. The authors of the paper stress the importance of the Lower and Middle Jurassic deposits of India and propose that further fossil discoveries will help to clarify the evolutionary history of the Neosauropoda.

Birds that Evolve Greater Complexity are Less Biodiverse

By |2023-09-29T06:19:14+01:00September 24th, 2023|Adobe CS5, Animal News Stories, Main Page, Photos|0 Comments

Newly published research studying bird evolution suggests a link between complex skeletons and reduced biodiversity. As birds develop more complex anatomies, they also decrease in diversity, with fewer species as they become more specialised within specific ecological niches.

Studying Patterns in Bird Evolution

Researchers at the Milner Centre for Evolution at the University of Bath collaborated with colleagues at the University of Lincoln, University College London and the Chinese Academy of Sciences. Their findings have been published in the journal “Nature Communications”.

The team looked at 983 species across all major groups of living birds and measured the complexity of their skeletons by comparing the bones in their fore limbs (wings) and hind limbs (legs).

They found that less complex birds – those with a smaller differences between their fore and hind limbs – had more species diversity than those with higher complexity and a larger difference between their limbs.

As an example, birds such as pigeons, gulls and songbirds (passerines) have low skeletal complexity but a high diversity of species living in varied habitats across the world.

At the other end of the spectrum, flamingos, and ostriches have short wings in comparison to their legs, and so have more complex limb skeletons. Groups with more complex skeletons may occupy smaller niches and are less able to subdivide those niche spaces in order to produce new species.

Trapped in an Ecological Niche

Whilst evolution can produce forms with lower complexity, these findings suggest that birds with more complex skeletons have become more specialised over time and so more developmentally entrenched. This may make them less likely to evolve back to become simpler again. In essence, Aves with complex skeletons may find themselves trapped within a specific ecological niche.

Causes of Biodiversity

Professor Matthew Wills, (Milner Centre for Evolution at the University of Bath) explained:

“We wanted to understand what causes some groups of birds to be species rich and others to be species poor – although ecology obviously plays an important part, it doesn’t account for the huge differences we see in biodiversity.”

Professor Wills added:

“The received wisdom is that there is no direction to evolution – that selection can act in any direction. Our study suggests that, in birds at least, the more they specialise, the less they are able to give rise to new species.”

A Case of Putting All Your Eggs in One Basket

The scientists also found that birds with more complex skeletons were generally more ecologically specialised, occupying fewer habitats and foraging for food in less varied ways.

Lead author of the paper, PhD student Andrew Brinkworth (Milner Centre for Evolution at the University of Bath) stated:

“Species can evolve to be specialised, and fill very small niches. However, in doing so, they restrict the number of routes they can evolve further, meaning they are likely to be less resilient to changes in the environment such as those caused by habitat loss, disruption to food chains and climate change.”

Andrew added:

“From our findings we predict that birds with more complex skeletons and less diversity will be at greater risk of extinction from these changes.”

Wider Implications for Bird Evolution and Animal Life

The researchers intend to broaden their research to see if this pattern is repeated in other animal groups. It would be interesting to see if this relationship between complex skeletons and reduced biodiversity can be identified in extinct groups, including theropod dinosaurs.

Could such a pattern be identified in the Theropoda to bird evolution lineage?

Fossil Feather Proteins Can Persist over Deep Time

By |2023-09-28T06:20:31+01:00September 22nd, 2023|Dinosaur Fans, Main Page, Palaeontological articles, Photos of Everything Dinosaur Products|0 Comments

Researchers including scientists from University College Cork (Ireland) have demonstrated that fossil feather proteins can persist over deep time. Using sophisticated and highly sensitive X-ray techniques the team have clarified the chemical composition of feathers preserved in the fossil record.

Identifying Fossil Feather Proteins

The study, published in “Nature Ecology and Evolution” provides a new perspective on feather evolution. Earlier research had suggested that primitive feathers had a different chemical composition to that of the feathers of extant birds. The new research reveals that the protein composition of modern-day feathers was also present in the feathers of dinosaurs and enantiornithine birds. The researchers conclude that the chemistry of feathers originated much earlier than previously thought.

The study was led by Dr Tiffany Slater and Professor Maria McNamara (School of Biological, Earth, and Environmental Science, University College Cork). They worked in collaboration with scientists at Linyi University (China) and the Stanford Synchrotron Radiation Lightsource in the USA.

The feathers of the Early Cretaceous dromaeosaurid Sinornithosaurus were analysed. In addition, the integumentary covering of the enantiornithine Confuciusornis was studied.

Commenting upon the implications of their study, Dr Slater said:

“It’s really exciting to discover new similarities between dinosaurs and birds. To do this, we developed a new method to detect traces of ancient feather proteins. Using X-rays and infrared light we found that feathers from the dinosaur Sinornithosaurus contained lots of beta-proteins, just like feathers of birds today.”

Fossilised Proteins

Fossil proteins are valuable tools in evolutionary biology. Recent technological advances and better integration of experimental methods have confirmed the feasibility of biomolecular preservation in deep time, yielding new insights into the timing of key vertebrate evolutionary transitions.

Keratins (formerly α-keratins) and corneous β-proteins (CBPs, formerly β-keratins) are of particular interest to palaeontologists. These proteins define tissue structures that underpin fundamental physiological and ecological strategies and can provide evidence to help map how feathers evolved.

As well as using infrared and sulphur X-ray spectroscopy to plot chemical signals, the team also conducted taphonomic experiments to help them to understand how feather proteins break down during fossilisation.

Dr Slater explained:

“Modern bird feathers are rich in beta-proteins that help strengthen feathers for flight. Previous tests on dinosaur feathers, though, found mostly alpha-proteins. Our experiments can now explain this weird chemistry as the result of protein degradation during the fossilisation process. So, although some fossil feathers do preserve traces of the original beta-proteins, other fossil feathers are damaged and tell us a false narrative about feather evolution.”

Surviving the Fossilisation Process

This study confirms that fossil feather proteins can survive fossilisation, that these proteins can persist through deep time.

Senior author of the study, Professor Maria McNamara (University College Cork) commented:

“Traces of ancient biomolecules can clearly survive for millions of years, but you can’t read the fossil record literally because even seemingly well-preserved fossil tissues have been cooked and squashed during fossilisation. We’re developing new tools to understand what happens during fossilisation and unlock the chemical secrets of fossils. This will give us exciting new insights into the evolution of important tissues and their biomolecules.”

As predicted by the experiments conducted by this study, analyses of Mesozoic feathers confirm that evidence of feather corneous β-proteins (CBPs) can persist through deep time.
