Un Autre Monde Posted July 24, 2021 Share Posted July 24, 2021 Hi there, Whilst clearing a pile of rocks from an excavation for a septic tank at our house in Burgundy we came across what appear to be several large teeth. They are smooth and conical in section and the largest is around 8 inches or 200mm long. We regularly find Ammonites and Belemnites as well as other marine creatures but have never seen anything like this before. In the same pile of rocks there also appear to be some small bones which are, for us, also unusual. Grateful for any ideas as to what they might be from….

JimB88 Posted July 24, 2021 Share Posted July 24, 2021 They look more like the internal molds of large bivalves to me. There's no bone structure that would indicate teeth. 2 Link to comment Share on other sites More sharing options...

Un Autre Monde Posted July 24, 2021 Author Share Posted July 24, 2021 Yep, I can see that: We did find what I’m guessing is an unusual Ammonite pair from the same excavation though.... Thanks for your input everyone xx 2 Link to comment Share on other sites More sharing options...
