From the album: The Mollusca of the Banjaard
A small common oyster specimen, with a nice brown coloration. Fossil oyster shells can be frustratingly difficult to tell apart from modern specimens. Different oyster species can be very hard to recognize, but O. edulis is by far the most common, so it's usually a reasonably safe bet (the other species are rare Pliocene to Eocene species and are very rarely found).

A very small damaged oyster specimen. Fossil oyster shells can be frustratingly difficult to tell apart from modern specimens. Different oyster species can be very hard to recognize, but O. edulis is by far the most common, so it's usually a reasonably safe bet (the other species are rare Pliocene to Eocene species and are very rarely found). Note: this particular specimen is pretty cool, because it's a great example of bioimmuration. Can you see those weird lines on that shell on the left hand side? That's the imprint of another shell species (bivalve or gastropod) which the oyster grew attached to. Status: still locally alive Fossil occurrence: common© 2019 Max DEREME

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!
