From the album: The Mollusca of the Banjaard
A nice example 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). Contrarily to the other specimen shown in this album, this shell's shape is much more similar to the extant Corbicula fluminalis, and could possibly be one (and, if the 'tear-drop shape' Corbicula is recognized as a new species, this one will probably be separate from it). Status: still locally alive (in freshwater bodies, not in the sea) Fossil occurrence: rather common© 2019 Max DEREME

From the album: The Mollusca of the Banjaard
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.

From the album: The Mollusca of the Banjaard
An incomplete bittersweet clam specimen. Because the hinge is missing, it becomes very hard to determine which species it is, which also makes it difficult to determine the age of the specimen, as both Pliocene and Eemian (which contain different species) sediments occur on the Banjaard. Chances are higher that it's an Eemian species, simply because Eemian sediments are more common, but no definite conclusion can be drawn.

Hi everyone, Last month, as I stayed a weekend at my grandparent's house, we decided to go to the Banjaard beach for some fossil hunting. I had asked Bram Langeveld (Natuurhistorisch Rotterdam) and Ronald Pouwer (Naturalis) which one of the "Zeeuwse stranden" (beaches of Zeeland, a province in the south-west Netherlands) was currently the best to hunt at. Both said that they were hearing some good stuff about the Banjaard beach recently, which has mainly Pleistocene fossils (including Eemian shells). Seeing that I can also find Eemian shells and other Pleistocene stuff at the Zandmotor, my usual hunting spot, I was a little reluctant at first, but still ended up going there. Good thing I did, because it was a rather successful hunt! The weather was really nice, bright blue skies and fresh (but not cold) temperatures.
