Vieira Posted October 11, 2017 Share Posted October 11, 2017 Hello, I need help to identify this tooth, found by me in a Jurassic formation in Portugal. My first thought it's Pterosaur. I wait for your opinions. The tooth have 1cm. Thanks, Filipe Link to comment Share on other sites More sharing options...

Troodon Posted October 11, 2017 Share Posted October 11, 2017 I don't know, there are no pterosaurs that I'm aware of described from that fauna however Rhamphorhynchid type teeth have been found. The only paper I have shows an indeterminate photo (b) of one. (Scale bar is 10mm) Is the base of your tooth round or oval. 1 Link to comment Share on other sites More sharing options...

ynot Posted October 11, 2017 Share Posted October 11, 2017 Nice find whatever it is. Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

Troodon Posted October 11, 2017 Share Posted October 11, 2017 If it's oval it looks a lot like the Pterosaur teeth you see from the Kem Kem. Are there marine deposits where you collect, I'm not aware of any. 1 Link to comment Share on other sites More sharing options...

You can find a theropod tooth and a fish tooth or scale in the same place. Link to comment Share on other sites More sharing options...
Troodon Posted October 11, 2017 Share Posted October 11, 2017 Marine not being fresh water but ocean. When I relooked at your tooth it appears to have a cutting edge is that correct? Link to comment Share on other sites More sharing options...

Sorry Troodon, you right. 33 minutes ago, Troodon said: When you look at your tooth it appears to have a cutting edge is that correct I'm not certain but I think so. Tonight I will see better those details.... Link to comment Share on other sites More sharing options...
Troodon Posted October 11, 2017 Share Posted October 11, 2017 Could be croc if the cutting edge is present and the base round Link to comment Share on other sites More sharing options...
paleosil Posted November 12, 2017 Share Posted November 12, 2017 Hello! Yes, it's a Rhamphorhynchus Sp. not extremely rare in Lourinhã formation, What is TRULY rare is the fact that is so complete (mostly are incomplete specimens ) and the extensively presence of the thin enamel that vanishs from other finds. Grande achado! Carlos N Dinocasts Rule? :)))))))))))))))) Link to comment Share on other sites More sharing options...
