Corbicula cf. fluminalis

A great specimen of the freshwater clam. This is a freshwater species, and therefore does not come from the Eemian stage of the Late Pleistocene like most other Banjaard shells (this one might be around 400'000 years old, but it's not sure). 

This one has the typical "tear-drop" shape of the fossil Corbicula's found in Dutch Pleistocene. They are significantly higher, slightly bulkier and more robust than the modern Corbicula fluminalis. Scientists are still debating as to whether it should be a separate species or not. 

Status: still locally alive (in freshwater bodies, not in the sea)

Fossil occurrence: rather common
