Last year, Ms. Kenselaar found it on the beach at Den Hoorn. The shell for a while remained in her cottage, but last week she took it to Ecomare. Curator Arthur Oosterbaan showed it to various experts, and they all said the same thing: Venericor planicosta. It lived in our region in the early and middle Eocene. That’s about 15 million years after the extinction of the dinosaurs. Europe then was an archipelago with a subtropical climate.
In the Netherlands, until this discovery, this fossil species had really only been known from the south-west of the country.
