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 inopinatus is known from the formation.^[2] Shark teeth are also known from the formation, including those of an indeterminate lamniform shark and Palaeospinax (formerly Synechodus).^[3]
