JorisVV Posted June 23, 2023 Share Posted June 23, 2023 This is a very nicely preserved Pliosaur tooth from Goulmima apparently. It has the details of a Pliosaur tooth. Only question is the color. Lots of them are brown to red colors. This one is grey/black. Could this be from a different location? Link to comment Share on other sites More sharing options...

pachy-pleuro-whatnot-odon Posted August 7, 2023 Share Posted August 7, 2023 I wonder who told you that... Because that's not what this is. This is not a pliosaur tooth but a polycotylid, which you can tell from the striae remaining low around the base of the tooth. Which of the two - Thililua longicollis or Manemergus anguirostris - is hard to say as the colours and preservation are indeed different from what you usually see. However, there are two types of matrix known from the Akrabou Formation: yellow marl-like matrix and grey calcitic nodules. Both have different types of preservation (with the nodules occasionally yielding better preservation, but much more difficult to prep). This distinction would explain why the specimen looks so different from what you normally see come out of Goulmima. However, again, not a pliosaur... 2 '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...
