Hi all, What species of Ostrea do you think this is? My first thought was O. edulis, but I am wondering if it maybe isn't O. ventilabrum after all. In fact, how exactly can you differentiate the two different species? It was found on the Zandmotor, Netherlands. Most of the shells found here are (apart from modern) from the Eem Formation, Eemian, Pleistocene; 120'000 years old. And it would be this old if it is an O. edulis (which is a very common species). But maybe it is the rarer Eocene O. ventilabrum? I know that they do occur here too, but I never know how to tell them apart from O. edulis. Looking forward to hearing your answers! Max
