Triassic Ammonoids

Here's a pile of Triassic ammonoids thrown together on my desk. Ceratites and Discoceratites (19 cm) from Germany at the back, then two Choristoceras from Austria, Halorites from Indonesia, Meekoceras from Crittenden Springs, a French Ceratites, a Crittenden Springs Dieneroceras and a few Greek specimens (Sturia, Flexoptychites, Cladiscites and Arcestes).

I blame TONMO. I thought a year of curiosity about these creatures would be enough, but no I'm still quite fascinated by them.

I have a memory of camping as a teenager in a grove of cherry trees in Alsace just next to a quarry yielding Ceratites. I brought a couple of them back, but don't remember what happened to them.

Wow! It looks almost man-made with the color and texture differences between the rock and the fossil. Has it been coated or sanded to get that effect? Welcome back!!!!

Thanks all. Yes Terri - white calcite against red matrix looks great. I think they have lightly air abraded this one D. The aesthetics attracted me, but also the connection with that little Omani Ophiceras. By the way I have reincarnated in a strange land that has no wild cuttlefish.

It would be fun to visit the outcrops of this limestone in person. Has anyone been there?
Wouldn't that be a glorious trip? Have you seen any other associated fauna from this locale? I wonder if they're perserved in the same way?
