If he sees this that would make me so happy! Now this was hard to draw. I'm not satisfied with how the eyes turned out and my pencil decided to freak out and leave a smudge on his nose that I couldn't erase, so I had to get rid of it digitally as best I could. All in all I think it's alright.
Darren Naish is a British vertebrate palaeontologist, author, and science communicator. He is well known for his research on dinosaurs and other Mesozoic reptiles, including Eotyrannus, Xenoposeidon, and azhdarchid pterosaurs. Much of his work has focused on fossils from the Wealden Group on the Isle of Wight. Naish founded the vertebrate palaeozoology blog Tetrapod Zoology and has written several popular science books. He frequently appears in media and serves as a scientific consultant for film, television, museums, and exhibitions. Additionally, he has examined cryptozoology and sea monster sightings from a scientific perspective.
Naish earned a geology degree from the University of Southampton and later studied vertebrate palaeontology under David Martill at the University of Portsmouth, where he obtained both an M.Phil. and Ph.D.. His doctoral work focused on the basal tyrannosauroid theropod Eotyrannus, which he and colleagues named in 2001. He has published research on various theropods, including Thecocoelurus, Calamospondylus, and Aristosuchus. Naish has also contributed to studies on sauropod dinosaurs, pterosaurs, fossil marine reptiles, turtles, and marine mammals. His work includes a reinterpretation of the Romanian fossil Heptasteornis, which he and Gareth Dyke argued was an alvarezsaurid.
Beyond his research, Naish has played a significant role in palaeoart and science communication. He co-authored All Yesterdays, a book that explores speculative reconstructions of dinosaurs and other prehistoric animals. The book challenges traditional palaeoart by depicting dinosaurs with plausible but unconventional adaptations. Naish also served as the lead consultant for the Apple TV+ documentary series Prehistoric Planet, which aimed to depict prehistoric life with scientific accuracy. His contributions have helped shape modern interpretations of dinosaurs and their behavior.

🐢 Check out this gorgeous chunk of 33 million year old soft-shell turtle (Trionyx) carapace from the north coast of the island yesterday!
Fossil turtle shell is a super common find on the north coast of the Isle of Wight! Our beaches are full of it! They come from our Late Eocene/Early Oligocene Solent Group clays, and can be found along with the fossils of alligators, fish, birds and mammals!
The Isle of Wight during the Oligocene was a swampy and subtropical landscape! So much so that Trionyx is only found in Africa and the Middle East today!

DINOVEMBER
2 - Hypsilophodon foxi (From Greek "high-crested tooth") - Early Cretaceous (130-125 Ma BCE) - Wessex Formation, Dorset and Isle of Wight, United Kingdom One of the most abundant fossils found on the Isle of Wight, the Hypsilophodon was one of the first dinosaurs studied by the British Museum, including by Richard Owen and Gideon Mantell in the 19th century. A bipedal and relatively small animal, only 2 meters long and weighing around 20 kg, this small ornithopod is one of the best studied members of its clade, having both characteristics considered "primitive", like five digits in its upper limbs, as well as advanced ones, including a "thumb" between these fingers, possibly used to manipulate their food, being also one of the best adapted dinosaurs for running, with rigid tail, long legs and aerodynamic trunk. Hypsilophodon's habitat, in the Wessex Formation, was a large area of woodlands and floodplains, with several lagoons, in addition to strong periods of drought and certain parts of the year, with Europe divided into several islands during much of the Mesozoic. According to some scholars, hypsilophodons would occupy a niche similar to that of small deer, such as duikers and chevrotains, feeding on various plants, such as ginkgos and cicadas. It shared its environment both with other larger herbivores, such as Iguanodon and Polacanthus, and with voracious predators, such as the spinosaurid Baryonyx and Eotyrannus, a primitive tyrannosauroid, as well as with turtles, lizards, primitive mammals and Enantiornithes, an avialan dinosaur clade very similar to modern birds, but retaining teeth and claws on their wings.
- Color scheme based on a Zebra Duiker (Cephalophus zebra) for the Hypsilophodon and a Barn Swallow (Hirundo rustica) for the Enantiornithid.

RARE: Turtle Exoskeleton Fossil – Barton Beds, Eocene, Whitecliff Bay, Isle of Wight UK
This listing features a rare fossilised turtle exoskeleton fragment, sourced from the Barton Beds at Whitecliff Bay, Isle of Wight, UK. This specimen dates to the Eocene Epoch, making it over 40 million years old and a significant piece of the UK’s palaeontological heritage.
Fossil Type:
Specimen: Turtle Exoskeleton (Shell fragment – likely carapace or plastron)
Represents a chelonian (turtle or tortoise) from the Eocene vertebrate assemblage of southern England
Geological Context:
Period: Paleogene
Epoch: Eocene
Stage: Bartonian (~41.3 to 38 million years ago)
Formation: Barton Group (formerly part of the “Barton Beds”)
Depositional Environment: Coastal lagoon and estuarine settings. The Barton Beds were laid down in a warm, subtropical marine and marginal marine environment rich in vertebrate and invertebrate fossils.
Morphological Features:
Curved or slightly flattened dermal bone typical of chelonian shell fragments
Surface may show granular texture or faint impressions of scute boundaries
Brown-grey fossilisation with natural wear and mineralisation from estuarine clays
Scientific Importance:
Fossil turtle material from the Barton Beds is rare and valuable for understanding Eocene coastal ecosystems in Britain
Specimens like this may be attributable to genera such as Trionyx or other soft-shelled or hard-shelled turtle lineages found in European Eocene sites
These fossils help reconstruct the palaeobiogeography of marine reptiles in the early Cenozoic
Locality Information:
Whitecliff Bay, Isle of Wight, UK – a historically significant fossil site with well-exposed Barton Beds yielding both marine and terrestrial Eocene fossils. A known locality for rare turtle remains, crocodile teeth, and fish fossils
Authenticity & Display:
All of our fossils are 100% Genuine Specimens and are provided with a Certificate of Authenticity. The photographs show the actual fossil for sale. Please see the photo for full sizing – note that the scale rule cube = 1cm.
This is a scientifically intriguing and display-worthy Eocene turtle exoskeleton fossil from one of Britain’s most productive fossil sites. A fine addition to any fossil collection, especially for those interested in ancient reptiles or the palaeontology of the British Isles.
Own a real piece of early Cenozoic history—fossilised remains from over 38 million years ago!
