sjaak Posted December 4, 2016 Share Posted December 4, 2016 Hello, Found this tiny tooth of about 1 x 1 cm in marine Jurassic sediment in the Boulonnais. North of France. Could this be a marine crocodile tooth, such as machimosaurus? Regards, Niels Link to comment Share on other sites More sharing options...

tmaier Posted December 6, 2016 Share Posted December 6, 2016 OK you bone and teeth people, are you asleep at the switch or what? How did this get no opinions? Looks like a croc tooth to me, but I'm not a bone of tooth person, so take that lightly. 1 Link to comment Share on other sites More sharing options...
belemniten Posted December 6, 2016 Share Posted December 6, 2016 I am not familar with the location but it looks indeed like a croc tooth ... Maybe Steneosaurus ... More prep will help to Id this tooth. Nice find ! 1 Many greetings from Germany ! Have a great time with many fossils Regards Sebastian Link to comment Share on other sites More sharing options...
jpc Posted December 7, 2016 Share Posted December 7, 2016 I don't know marine croc teeth, but croc is a pretty good guess for a broken tooth. 1 Link to comment Share on other sites More sharing options...
sjaak Posted December 7, 2016 Author Share Posted December 7, 2016 Thank you very much for your replies! So you think that this is the tip of a larger tooth that was broken? That makes sense. Maybe I will do some further prep work. Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted January 10, 2021 Share Posted January 10, 2021 It's the tip of a Machimosaurus sp., identifiable by its blunt shape and anastomosing ridges. Compare against below image (figure 1 from Young et al., 2014. Tooth serration morphologies in the genus Machimosaurus (Crocodylomorpha, Thalattosuchia) from the Late Jurassic of Europe): 2 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
