Lying unconformably upon the well-known Liassic beds of Black Ven, the cliff which overhangs the sea-shore between Lyme Regis and Charmouth, occur beds of Cretaceous age, representing the Gault and Upper Greensand of other localities. The lower beds consist of loams, dark and almost black where the clay predominates over the sand, and lighter where the sand is present in larger quantities. Above these loams are yellow sands containing indurated nodules called ‘Cowstones,’ which, with the ‘Foxmould’ sands above them, have been considered to represent the zone of Schlœnbachia rostrata (Sowerby). The dark loams below them represent, therefore, the zone of Hoplites interruptus (Bruguière).
