Per Christian Posted August 17, 2021 Share Posted August 17, 2021 (edited) Here is a 7 cm long tooth, claimed to be pliosaur. What do people here think? It's from Morocco, unsure where specifically. @pachy-pleuro-whatnot-odon Edited August 17, 2021 by Per Christian Link to comment Share on other sites More sharing options...
Troodon Posted August 17, 2021 Share Posted August 17, 2021 Do you have any locality, age and formation? You did say unsure. Any side photos where it attaches to the matrix? Looks like a composite in the middle of the crown. Link to comment Share on other sites More sharing options...

Here's another image too, and on it, it looks a bit fishy i think. I'll request close up of where it attaches to the matrix Link to comment Share on other sites More sharing options...
Troodon Posted August 17, 2021 Share Posted August 17, 2021 Thats great, it the marine area. Ill leave the ID to those more knowledgeable but would suggest a closeup of the side and middle area that looks composited.

Yeah i requested more pictures, hopefully I'll get them. When i do I'll post them here Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted August 17, 2021 Share Posted August 17, 2021 Preservation and matrix are indeed consistent with Goulmima. And while the preparation is horrible on this (as with the other teeth before), I think this is definitely a contender for pliosaur. For one, I haven't ever seen such a robust root come out of Goulmima before. For another, the striations running the full apicobasal height of the tooth is also much more in-line with local pliosaurs rather than polycotylids or Libonectes morgani. Seeing as how uncommon this tooth morphology is, I have no doubt that tooth and root parts belong together. But I do think the tip has been glued back wrongly after it broke off. It's been twisted 90 degrees from what it should be, which is the bulbous part of the root - thus pointing towards the measuring tape. Better pictures of ornamentation, the side and the break would be useful, but I doubt they'll clear up much more seeing as how much is obscured by the glue and bad prep-job... As such, this tooth could greatly benefit from additional prep-work, as this is sure to make it come out better. All the same, extremely rare to find a rooted pliosaur like this... 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...
Mike from North Queensland Posted August 17, 2021 Share Posted August 17, 2021 A slight S shape to teeth in pliosaur's does occur in some species so repair may not be incorrect. The tooth does look like pliosaur from photos. 1 Link to comment Share on other sites More sharing options...

The tooth does look like pliosaur from photos. Do you have any examples? Because I don't think I've seen any like that before... And in that I'm assuming you don't mean like in your avatar either, right? That is, although I can imagine seeing an S-curve in that as well, the crown curves one way, the root another. But I take it that's not what you mean... The only teeth that I've seen that exhibit such a curve are fish teeth. So I would be very interested to learn about this specific morphology in plesiosaurs...

pachy-pleuro-whatnot-odon Posted August 18, 2021 Share Posted August 18, 2021 So I just bumped into this beautiful brachauchenine pliosaur tooth from Goulmima on Instagram, and thought I'd share for comparison. It also shows the correct curvature for these teeth 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...

Seems I've found my first pliosaur tooth then, and it's all thanks to you guys. This forum is amazing, I can't believe it's all free 1 Link to comment Share on other sites More sharing options...
