connorp Posted May 24, 2019 Share Posted May 24, 2019 I just found this guy in some old boxes. I lost the ID card, but if I remember correctly, it came from France. I don’t know ammonites so I have no clue if this could be identified at all without a precise locality. Link to comment Share on other sites More sharing options...
Natalie81 Posted May 24, 2019 Share Posted May 24, 2019 Do you know from where in France? Or the age? It does ressemble to Pavlovia from the Jura... 1 Link to comment Share on other sites More sharing options...

connorp Posted May 25, 2019 Author Share Posted May 25, 2019 Perisphinctes does sound correct now that I try to think back. But I’m not so sure it was from France anymore. It was purchased from a rock store in Paris but may have been from elsewhere. Oh well. Thanks for the help! Link to comment Share on other sites More sharing options...
Ludwigia Posted May 25, 2019 Share Posted May 25, 2019 Perisphinctes is one possibility, but it could also be a Parkinsonia. Pity you don't know the provenance. That would solve the riddle. You'd need to find someone familiar with the ammonite fauna in French strata and sites if that's the country of origin. Greetings from the Lake of Constance.

caterpillar Posted May 25, 2019 Share Posted May 25, 2019 No Parkinsonia for me. The ombilic and the ribs are different. Certainly Perisphinctes (Dichotomosphinctes). But from where? That's the question http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
