Ammonites from Caen, France

A number of Ammonite species are found in the region around Caen France. The rocks are Jurassic (Toarcian to Callovian) in age and between quarries and farm fields, quite a few specimens can be found.

Parkinsonia parkinsoni Bajocian stage (169 mya)

Hildoceras bifrons Toarcian stage (180 mya)

Perisphictes sp. Bajocian stage (169 mya) - This specimen has Quartz crystals that formed within the voids between chambers.

Oppelia subradiata Bajocian stage (169 mya)

Stephanoceras sp. Bajocian stage (169 mya) Like the Perisphictes above, this specimen has Quartz crystals that formed within the voids between chambers also.

A second, smaller specimen.

My thanks to Gery for sending me all of the above specimens.
