Brevicollis Posted March 21 Share Posted March 21 More Pictures (all sides, cross section) would be helpfull. But I think theres a good chance for it beeing a Baryonyx tooth. Spinosauridae teeth usually have serrations on the carina, and also stripes. But Pliosaur and Croc teeth can look similar too. And because I am not familiar with the age and location of the formation, I can't state the ID. I hope for you, it is Baryonyx ! Great find ! Are good signatures really that important ?

Joe Jordan Posted March 21 Author Share Posted March 21 (edited) Hi thanks it's early Cretaceous 140myo the tooth is also oval Edited March 21 by Joe Jordan Link to comment Share on other sites More sharing options...
Brevicollis Posted March 21 Share Posted March 21 Okay, sounds like it is Baryonix. Baryonix is from the early cretaceous, but whithout the rigth pictures, its hard to tell. It would be nice, If you post the requested pictures. Whats the sice of it ? Are good signatures really that important ? Link to comment Share on other sites More sharing options...

So why shouldnt it be one. But because many Spinosauridae are known from England that are so fragmentary preserved that its not clear If they are multiple species or not. I wouldn't label it as Baryonyx, rather, ... Spinosaurid indet. Great tooth by the way, not a daily find ! 1 Are good signatures really that important ?

Joe Jordan Posted March 25 Author Share Posted March 25 I didn't think spinosaurs had serrations on there teeth . We have loads at the museum and they don't have any .? Link to comment Share on other sites More sharing options...

Dinosaur teeth can only rarely be confidently assigned to species or even genera. Link to comment Share on other sites More sharing options...
Anomotodon Posted April 12 Share Posted April 12 I’d be a bit more cautious calling this a Spinosaurid based on serrations alone. Symmetrical labial/lingual surfaces, large, evenly spaced ridges and lack of distal curvature are more typical of crocodylians. Serrations are difficult to use as a diagnostic trait - many non-ziphodont crocs (and mosasaurs) can have similar, very fine denticles. For example, a Pliocene Crocodylus: The Tooth Fairy Link to comment Share on other sites More sharing options...

But on most examples, they're so worn down or erodet, that they're not recognizable anymore. But in rare accasions, even they preserve. Are good signatures really that important ?
