DanJeavs Posted September 5, 2018 Share Posted September 5, 2018 So I recently purchased this ammonite off of the popular auction site for a good price, not something I usually do, but it looked nice and was already out onto a plinth. Unfortunately the seller doesn’t know where or when it was collected, and my knowledge only really expands along the yorkshirecoast in the U.K. I was wondering if anybody could help me with identification please. Thanks. Link to comment Share on other sites More sharing options...
Max-fossils Posted September 5, 2018 Share Posted September 5, 2018 No clue what species that is, but that's a gorgeous display piece! Nice buy!

Iv been scouring EBay for months waiting for somebody who probably doesn’t know anything to chuck something up for next to nothing. It finally happened. Even better that it came mounted on a nice plinth. Link to comment Share on other sites More sharing options...

Ludwigia Posted September 5, 2018 Share Posted September 5, 2018 Sorry I can't help you much with this one. For one thing it's lacking in external details like sutures or rib structure, which makes determination rather difficult. Ammonites with this form (oxycone) can be found from the Triassic through to the Cretaceous. All I can say is that I can't think of anything like that from the Jurassic. I suspect that it might be from the Cretaceous, but that's actually just a shot in the dark. Pity that the seller can't at least tell you which country it comes from.

The outer form would fit, but the venter should be flat, whereas by this one it's sharp. Greetings from the Lake of Constance.

PFOOLEY Posted September 18, 2018 Share Posted September 18, 2018 @DanJeavs, very cool ammonite. How the shell whorls near the umbilicus looks similar to that in (Upper Cretaceous) Placenticeratids...you might start comparing yours with the genus Placenticeras and go from there. Nice acquisition and good luck. Edit: take a peek at @Foshunter's gallery on the Blossom Sand. "I am glad I shall never be young without wild country to be young in.
