Dear Guys,
I recently prepared one bigger tooth I have found in flint erratic, it is 1 cm length, crimson and little curved with blunt upper end unusual to shark.
The edges are little serrated but I wouldn't expect dinosaur. However, I think it is also not from bony fish and the serrations look more reptile like.
Plesiosaurs and elasmosaurs have quite rounded cross section in teeth, so maybe it is from Pachyvaranus, etc.?
Any idea what is this?
Best Regards
Domas
