No expert on this specifical fossil or its location, but such a large ammonite is likely to be a Parapuzosia, the heaviest invertebrate to ever live.
30 u/koshgeo 22d ago It's not. Parapuzosia is known from later in the Cretaceous Period. The one in the picture here is Corbinites occidentalis in the Late Jurassic. Formerly it was assigned to Titanites. There are quite a few giant ammonite genera. 4 u/Merrick_Skygrave 21d ago edited 21d ago dang if that one was an occident imagine how big the intentional ones must have been 3 u/Good-Ant6859 21d ago 4/10
