After visiting Bempton we moved on to Speeton ...lots of belamnites and ammonites...


Scratting in the clay...glad it was dry!

The detail.....The Speeton Clay Formation is a highly fossiliferous formation that yields a wide range of Lower Cretaceous fossils.

Hibolites jaculum (and others) and Acroteuthis lateralis belemnite rostrums.
