LordTrilobite Posted October 22, 2017 Share Posted October 22, 2017 Doesn't look like Mosasaur to me. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
JohnBrewer Posted October 22, 2017 Share Posted October 22, 2017 I agree. They look like Onchopristis to me. Bottom left. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
Troodon Posted October 22, 2017 Share Posted October 22, 2017 I don't see enamel, unless it's worn so it might not be an oral tooth. A rostral tooth possibility is Peyeria but it's a long shot since there is no ribbing. Link to comment Share on other sites More sharing options...
Anomotodon Posted October 22, 2017 Share Posted October 22, 2017 Hi @Sergio41! As far as I know, Peyeria is sometimes considered a ray dermal denticle, rather than a rostral tooth (Cappetta, 1987; Wueringer et al., 2009). Anyways, both Peyeria and ray denticles have a more or less distinct labial side (as indicated by the arrows), that this specimen is lacking. I was leaning towards a fish tooth. Has anyone encountered any similar specimens in Cretaceous? The Tooth Fairy Link to comment Share on other sites More sharing options...
old bones Posted October 23, 2017 Share Posted October 23, 2017 Nice picture of those denticles. Link to comment Share on other sites More sharing options...
Sergio41 Posted October 23, 2017 Author Share Posted October 23, 2017 Thanks for the replies! I think anything from the offered did not seem to... Enamel, and on the other samples. But the enamel of aquatic reptiles is not as strong as the sharks. Could fall off... The teeth of fishes quite a lot in this layer. But they are not at all similar to this instance. (later I'll post a photo of the teeth of the fish) The holes at the base of my finds may be nutrient canals? Link to comment Share on other sites More sharing options...
