JURASSIC OYSTER
 
160 million years old
 
Oxford Clay
Warboys Pit, Cambridgeshire
  

The extinct oyster Gryphaea dilatata, together with its cousin Gryphaea arcuata from the Lower Lias, are distinctive fossils, known in folklore as ‘Devils toenails’. They have one shell, or valve, much larger than the other and strongly curved as an adaptation to living on a muddy sea floor.

  
This is a very good example of this fossil with both of the valves present. It was collected in the 1970s from the classic locality of Warboys in Cambridgeshire.
