I bought one of those Agadir ammonites today and from what I've red most of these specimens are unidentifiable because they lost their suture lines due to the chiselling job. The one I bought still had its suture lines intact despite the preparation done on it. What genus are these usually? I've had mantelliceras and olcostephanus as possibilities.

I live in Slovenia. I've been visiting this forum from time to time. Finally, I've decided to join and share my experience and thoughts. My main interest are the Mesozoic tetrapods. Above all: the dinosaurs. I am a paleo illustrator and a dinosaur ichnologist. You can learn more about me here: Mesozoic Mosaic Beri's dinosaur World (BDW)

I'm doing a survey of all valid plesiosaur genera described to date and so far, about 100 valid plesiosaur genera have been described so far. Has there been any published study regarding the estimated generic diversity of plesiosaurs?
