England's Island

Dinosaurs and Fossils on the Isle of Wight

Britain's dinosaur capital

The Isle of Wight is the richest dinosaur fossil site in Europe. The island's crumbling Cretaceous cliffs, particularly along the south-west coast, have yielded more dinosaur species than anywhere else in Britain. Palaeontologists have been finding fossils here since the early 19th century, and new discoveries continue to make headlines.

The Wessex Formation, a layer of Early Cretaceous rock exposed along the coast from Compton Bay to Sandown, dates back roughly 125 million years. When these rocks were formed, the Isle of Wight lay on a subtropical floodplain teeming with life. Large herbivores like Iguanodon and Polacanthus shared the landscape with predators including Neovenator and the early tyrannosaur Eotyrannus.

Fossil hunting is a popular activity, particularly after winter storms expose fresh material in the cliffs and on the foreshore. The best sites are Compton Bay, Brook Bay, and Yaverland. The island's Dinosaur Isle museum in Sandown houses the most important finds.

Species and Fossil Sites

Iguanodon

One of the first dinosaurs ever described, with the Isle of Wight providing some of the most complete and scientifically important specimens worldwide.

Early Cretaceous (130-125 million years ago)

Neovenator

The most complete large carnivorous dinosaur found in Europe, establishing the Isle of Wight as a globally significant site for theropod palaeontology.

Early Cretaceous (125 million years ago)

Polacanthus

One of the earliest known Cretaceous armoured dinosaurs, first found on the Isle of Wight and still one of the best-known ankylosaurs from Europe.

Early Cretaceous (130-125 million years ago)

Eotyrannus

One of the earliest known tyrannosaurs, revealing that the lineage which produced T. rex began as small, long-armed predators in Early Cretaceous Europe.

Early Cretaceous (125 million years ago)

Comptonatus chasei

The most complete dinosaur skeleton found in Britain in over a century, adding a new genus to the island's rich iguanodontian fauna.

Early Cretaceous (125 million years ago)

Brighstoneus simmondsi

A new iguanodontian genus that revealed previously unrecognised herbivore diversity in the Isle of Wight's Cretaceous ecosystems.

Early Cretaceous (125 million years ago)

Wessex Formation

The geological formation underlying the Isle of Wight's status as one of the richest dinosaur localities in Europe, continuously producing new specimens through coastal erosion.

Early Cretaceous (130-125 million years ago)

Fossil Hunting Guide

A practical guide to one of Britain's most accessible and productive fossil hunting locations, where significant discoveries continue to be made by amateur collectors.

Early Cretaceous (130-66 million years ago, various formations)

Compton Bay Fossil Sites

The most productive and accessible dinosaur fossil site on the Isle of Wight, yielding footprints, bones, and plant fossils on an ongoing basis through natural coastal erosion.

Early Cretaceous (130-125 million years ago)

Yaverland Fossil Sites

An important east coast fossil site noted for exceptionally preserved dinosaur footprints and material from the Vectis Formation that complements the south-west coast localities.

Early Cretaceous (125-120 million years ago)
