FOSSIL SEABED

About 3 million years old

Red Crag.   Bawdsey, Suffolk
 

Part of the sea bed at the very end of the Pliocene period, just before the onset of the Ice Age.

The Red Crag consists of shelly sands laid down in a shallow sea that covered most of Suffolk and Essex. The name derives from its reddish colour, and crag is an East Anglian word for shells. The colour is due to the oxidation of iron compounds originating in the underlying London Clay.


The sea was teeming with shellfish, mostly bivalves and gastropods, and it had a much greater biodiversity than the North Sea today. It was a high-energy environment with strong tidal currents resulting in broken shells, but many complete fossils are also found, including the teeth of sharks.

Bawdsey Cliff is a designated Site of Special Scientific Interest and digging in the cliff is not permitted. This piece of Red Crag is unusual as it has been naturally cemented into a hard rock. It is packed with fossil shell fragments and is an attractive colour. It was found on the beach after a storm.
