Name:Blue Lias
Derivation:Well, it looks slightly blue
Description: Blue-grey crumbly rock, with fossils in
The Blue Lias clay is very soft. It exists at Lyme Regis on the south coast of England and Whitby in Yorkshire. Both places are very good for fossils, such as ammonites and belemnites. Each of the specimens in the photoabove has a fossil in. The Blue Lias was a bed of clay which preserved the sea creatures' shells until they fossilised.
