Pleuromya Posted March 30, 2021 Share Posted March 30, 2021 Hi, I found this ironstone fossil inside a rock that I split earlier. It was full of some very nice fossils. I was wondering what this could be? It looks like a tooth, as it has many small upward facing points on one edge, but I imagine it is something else as there isn't enamel. Found in Northamptonshire, UK. I believe it is from the early Jurassic. It measures 1.8cm lengthways. Sorry the photos are quite zoomed out, the quality of the picture gets worse the closer I go. Many thanks. Link to comment Share on other sites More sharing options...
Thomas.Dodson Posted March 30, 2021 Share Posted March 30, 2021 Not one tooth but multiple teeth, if you count hinge teeth. You're correct in it being a bivalve. The general shape and comb like hinge teeth are consistent with Nuculanids from what I can see but I'd like to see more closeups. If you can narrow down the formation or group it might help too. 1 Link to comment Share on other sites More sharing options...

Thanks. I think it may be from the Dyrham formation, or possibly the Whitby Mudstone formation. Link to comment Share on other sites More sharing options...
