Alston Gee Posted January 21 Share Posted January 21 I recently acquired a tooth fossil from UK. The locality of the tooth labeled by the seller is Oxford Clay, but I suspect it might come from Faringdon Sponge Gravels due to its preservation. The tooth seems to have carinae, which rarely occurs on plesiosaur and pliosaur teeth. Can anyone help me identify this tooth? Would it possibly be a candidate for Dakosaur? 1 Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted January 21 Share Posted January 21 I think you're spot on with your determination of this having come from the Faringdon Sponge Gravels. The preservation is an exact match. Probably Wicklesham Pit. As for the identification of the specimen itself, I'd say you're right on target with that as well, seeing as pl(es)iosaurs indeed don't have carinae, let alone pinched ones. So this is certainly a metriorhynchid crocodile tooth. And seeing as the carinae do appear pinched, this would, indeed, be attributable to Dakosaurus sp.. Though the preservation of this specimen is obviously not the greatest, it being identifiable still makes it a really nice piece! Well done! 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
