Please can anyone identify this ammonite I found at Doniford it is younger than the beds containing Arnioceras.
Cheers

I am by no means an expert. But as a suggestion, might it be something out of the Teschenites Genus. Teschenites existed around the lower cretaceous and were also found in parts of western europe. I hope this helps[smile]

Hello, Andy`s blog shows an ammonite wich is similar; Angulaticeras.

greets, Bert
the search is as valuable as the finds...

Thanks both the rocks at Doniford are Lower Jurassic (L. Hettangian to L. Sinemurian) so will look at Angulaticeras.
The coiling is tighter than the image you sent Bert but could be a different species.
Will keep looking.
Cheers Jez

Given the locality and Lower Jurassic affinity, I'd probably place it in the genus Schlotheimia (characteristic generally of the Angulata Zone, towards the top of the Hettangian Stage).  I cannot be sure as it is crushed and the venter is not visible.

Thanks for that a species of Schlotheima looks promising, I have found several Schlotheima angulate at nearby St Audries Bay but their coiling is not as tight / involute.
