SailingAlongToo Posted March 5, 2018 Share Posted March 5, 2018 Looks croc-ish to me. I've found several croc teeth at Douglas / Liverpool and Purse, assuming you found it in MD Paleocene.

JohnBrewer Posted March 5, 2018 Share Posted March 5, 2018 Looks like croc to me too. John Map of UK fossil sites Link to comment Share on other sites More sharing options...
HoppeHunting Posted March 5, 2018 Share Posted March 5, 2018 I'd say croc. Does it have a cutting edge or is it entirely conical? The Hunt for the Hemipristine continues! ~Hoppe hunting!~ Link to comment Share on other sites More sharing options...
MDPaleoceneGeo Posted March 6, 2018 Author Share Posted March 6, 2018 It looks conical to me. I don't think its a Croc. Here is pic of tooth looking at tip and then at base. Tip Base Also - See URL below with similar tooth characteristics - "the teeth are conical, no cutting edge and pronounced striations" So I am leaning to a Plesiosaur tooth. Let me know if you all agree. http://www.fossilsofnj.com/reptiles/plesiosaurs.htm Link to comment Share on other sites More sharing options...
JohnBrewer Posted March 6, 2018 Share Posted March 6, 2018 I still think croc. What do you think @Troodon @LordTrilobite? John Map of UK fossil sites Link to comment Share on other sites More sharing options...
LordTrilobite Posted March 6, 2018 Share Posted March 6, 2018 It's hard to tell from the photos, but it looks like it has a subtle cutting edge on both sides. I would lean towards croc as well. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted March 6, 2018 Share Posted March 6, 2018 Cutting edges circled in red, I think. I'd say croc. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
LordTrilobite Posted March 6, 2018 Share Posted March 6, 2018 Yes Tidgy's Dad, those are the areas I meant that look like carinae. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
MDPaleoceneGeo Posted March 6, 2018 Author Share Posted March 6, 2018 Here is a better pic. Ok - I think I finally see the cutting edges (carinae). Wow - really hard to tell. Bummer - thought I had a Plesiosaur tooth. Thanks for your help. Link to comment Share on other sites More sharing options...

Miocene_Mason Posted April 13, 2018 Share Posted April 13, 2018 Not sure how I missed this, awesome to find Cretaceous croc tooth, especially in MD! “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
