msantix Posted October 1, 2021 Share Posted October 1, 2021 Hi, I feel this is a silly question to ask, since I should know by now how to identify Pliosaur teeth, and I am mostly certain this in indeed a Pliosaur tooth but anytime I am going to spend plenty of money on a fossil, I feel like I should just spend a minute making a thread on this forum just to confirm. The tooth is 4cm in length & comes from the Akrabou Formation in Morocco (a little bit of restoration on one side which the seller has made clear about). Thank you! 1 Link to comment Share on other sites More sharing options...
bthemoose Posted October 1, 2021 Share Posted October 1, 2021 I believe this same tooth is discussed here: Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted October 1, 2021 Share Posted October 1, 2021 @bthemoose beat me to it, but the above thread indeed discusses the same tooth. It's indeed a brachauchenine pliosaur tooth, only highly flattened due to plastic deformation (in addition to some repaired damage).

msantix Posted October 1, 2021 Author Share Posted October 1, 2021 Thanks, I didn't see the previous thread before, but the thread does confirm it as Pliosaur so thanks for letting me know! Link to comment Share on other sites More sharing options...

True, but their teeth look differently, with much finer striations restricted to the base of the tooth crown: 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...
