The Isle of Wight is one of the richest dinosaur localities in Europe, with over 20 species of dinosaur having been recognised from the early Cretaceous Period (in particular between 132 and 110 million years ago), some of which were first identified on the island, as well as the contemporary non-dinosaurian species of crocodile, turtle and pterosaur.
Geological strata Edit
The Isle of Wight has layers of the Vectis and Wealden fossil-bearing beds exposed on the southern half of the island. These are revealed in the cliffs of Yaverland, close to Sandown, and at Hanover Point and Whale Chine, along the southwestern coast.
The Cretaceous habitat Edit
The Island's dinosaurs come from the Wessex Formation, which dates from between 125 and 110 million years ago (mya). During this time the Isle of Wight, then located on a latitude at which North Africa resides today, had a subtropical environment and was part of a large river valley complex, which ran along the south coast of England to Belgium. It was a world of ponds, rivers and swamps, so it had conditions favourable for the formation of fossils.
As this environment did not change much, over the course of 10 million years, a large number of fossils were formed, so the island today is a very rich source.
List of dinosaur species Edit
Unless otherwise specified, the following is a list of dinosaurs for which almost complete skeletons have been found on the island. There are also many more species, known only from a single or very few bones.
Order Ornithischia Edit
- Suborder Ornithopoda ("bird-footed", bipedal herbivores)
- Suborder Thyreophora ("shield-bearers", armored herbivorous dinosaurs)
Order Saurischia Edit
- Suborder Sauropodomorpha ("sauropod-like", giant long-necked herbivores)
- Suborder Theropoda ("beast foot", bipedal carnivores)
- Baryonyx walkeri: Teeth are common on the Island. Hand bones have also been found.
- Eotyrannus lengi: possibly the oldest member of the tyrannosaurid family. First identified in 1997 and named in 2001 from a single specimen found on the island.
- Neovenator salerii: The holotype skeleton was found on the island.
- Yaverlandia: The holotype was found at Yaverland. It was initially believed to have belonged to a pachycephalosaurian.
