JohnBrewer Posted February 9, 2019 Share Posted February 9, 2019 Hello forumites Can’t seem to find an id on this ammo. I guess I might need to prep more to see the keel but it’s pretty fragile. Could Paraloid it I guess. Lower Oxford Clay Callovian, Jurassic Peterborough, Cambridgeshire, UK. Cube is 1cm3 @Ludwigia John Map of UK fossil sites Link to comment Share on other sites More sharing options...

Ludwigia Posted February 9, 2019 Share Posted February 9, 2019 @JohnBrewer I would rather tend to Kosmoceras. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

I would have expected that Kosmoceras had more spines? But there is indeed a lot of variation in those ammonites. The keel will have to be preppes out to be sure I think. 2 growing old is mandatory but growing up is optional. Link to comment Share on other sites More sharing options...

Quenstedoceras has more rounded whorls, which is why I still tend to Kosmoceras. 1 Greetings from the Lake of Constance.

I did wonder if that would be the case. The matrix is very soft, I hope the ammo isn't as soft. Pin vice I think for this one. Thanks guys.
