The Vectis Formation is a geological formation on the Isle of Wight, England whose strata date back to the Early Cretaceous (lowermost Aptian stage, 125 million years ago).[1][2] The Vectis Formation is composed of three geological members: the Shepherds Chine member, the Barnes High Sandstone member, and the Cowleaze Chine member. Dinosaur remains are among the fossils that have been recovered from the formation.[3]
