I am a retired palaeontologist from the Geological Survey of the Netherlands. My interest is in molluscs, molluscan biostratigraphy, palaeoecology and Pliocene and Quaternary stratigraphy of the North Sea Basin.
I'm mainly working on malacology and Quaternary (bio)stratigraphy of the Netherlands in the wikipedia-NL.

You may find some of my pictures of shells here.
