TNCollector Posted July 30, 2015 Share Posted July 30, 2015 I vote shark tooth, other than that I cannot narrow it down very far as I have never collected anywhere in Europe. Link to comment Share on other sites More sharing options...

Eocenecarnage Posted July 31, 2015 Share Posted July 31, 2015 I actually think it's a baby mosasaur tooth. I'm not expert in Polish fossils, so I may be wrong. Link to comment Share on other sites More sharing options...
fossilized6s Posted July 31, 2015 Share Posted July 31, 2015 Shark. I'd almost venture a guess at juvenile Mako type of shark. Most Mosasaur teeth I have seen are round. This is not. ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
TNCollector Posted July 31, 2015 Share Posted July 31, 2015 Its not Mosasaur. The third picture shows the thin enamel wall with the interior completely mineralized. The inside of shark teeth are made of much weaker material than Mosasaurs. The interior part of mosasaur teeth usually permineralize rather than replace.

Troodon Posted July 31, 2015 Share Posted July 31, 2015 I think TN is spot on. That third picture shows a crown with a thin wall which says shark to me. A Lamniform of some type. Link to comment Share on other sites More sharing options...
