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.
