Ferruginous Sands

The Ferruginous Sands is a geologic formation in England. It preserves fossils dating back to the Aptian Stage of the Cretaceous period. It consists of "a number of heavily bioturbated coarsening-upward units each comprising dark grey sandy muds or muddy sands passing up into fine-to medium-grained grey to green glauconitic sands."[1] The dinosaur Vectaerovenator is known from the formation.[2] Shark teeth are also known from the formation, including those of an indeterminate lamniform shark and Synechodus.[3]
