Speeton Clay

Named Rock Formations and Groups

The Speeton Clay Formation is a Lower Cretaceous claystone unit, roughly 145 to 100 million years old, exposed in Yorkshire on England's northeast coast and named for the village of Speeton. It represents a marine setting, in contrast to the terrestrial deposits of the contemporary Wealden Group farther south, and it holds abundant fossils, among them belemnites, ammonites and marine reptiles.
