Can anyone help me with the classification of this Triassic fossil?

[AkerCS]

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.

Possible nothosaurus femur and vertebra from the same site What do you think?

 

[Ludwigia]

Acrodus sp. might fit for the teeth, although, come to think of it, that's a fish and not a placodont

[Pemphix]

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.

Concerning the teeth: surface supports the Acrodus hypothesis of Ludwigia. 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]

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.

I think these teeth are very similar to Psephoderma teeth, a type of placodon.

What is your opinion?
