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
Hi all, I found this fossil oyster (Ostrea edulis) two days ago on the Zandmotor (Netherlands). It's from the Eemian stage of the Pleistocene (120'000 years old). What made me pick up this oyster was its really weird feature. In the inside, this looks like a normal oyster: But when you turn it around, you can see that this oyster had a really rough time! Part of it is completely crushed, pushed in. And there are weird lines on it too. Now of course, the first idea that came onto my mind was that this oyster got crushed when it got pumped out of the sea and thrown onto the beach. But this wouldn't really work, because if you apply just a bit of force anywhere on a fossil oyster, it will easily break/snap. It won't get a new shape. And I have no clue what might have made those weird lines on it. Therefore, I ask your opinion: what do you think happened to this oyster for it to become crushed (but not break), and have those weird lines? Looking forward to some interesting theories!
