AkerCS Posted November 11, 2019 Share Posted November 11, 2019 Hi. They were found in Muschelkalk facies of Ladinian. Bony remains of nothosaurs and placodontos appear in the area. In a book they appear classified as placodontos teeth, but I would like to specify more. Thank you. Link to comment Share on other sites More sharing options...
AkerCS Posted November 11, 2019 Author Share Posted November 11, 2019 Possible nothosaurus femur and vertebra from the same site What do you think? 1 Link to comment Share on other sites More sharing options...
Ludwigia Posted November 11, 2019 Share Posted November 11, 2019 Acrodus sp. might fit for the teeth, although, come to think of it, that's a fish and not a placodont Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...
Pemphix Posted November 12, 2019 Share Posted November 12, 2019 Concerning the bone i agree to femur and sauropterygian. I'm not convinced that it belongs to any nothosauridae (Nothosaurus, Paranothosaurus), cause it lacks the typical form and other specs. It has more features of Simosaurus sp. or Neusticosaurus sp.

Placodonts have no holes/caverns on the surface like those can be seen on your fossils. Maybe it is typical type of erosion, but more close-up photos would be needed to determine.... Unfortunately, there's no location or even area where it has been found and no scale at all. That makes it difficult to get a more detailed ID.

AkerCS Posted November 12, 2019 Author Share Posted November 12, 2019 Thank you very much for your responses. I put some more photos in detail and with scale. As for the teeth, I think they are very flat to be acrodus and in the book I mentioned they also have these holes. Link to comment Share on other sites More sharing options...

AkerCS Posted November 12, 2019 Author Share Posted November 12, 2019 I think these teeth are very similar to Psephoderma teeth, a type of placodon. What is your opinion? 1 Link to comment Share on other sites More sharing options...
