What is "bochianites"

Bochianites is a straight shelled ammonite which lived from the Upper Jurassic, Tithonian, to the Lower Cretaceous, Hauterivian. The shell long, narrow, moderately expanding; smooth or with weak to strong oblique annular ribs. Sutural elements short and boxy. The umbilical lobe, which lies between the lateral lobe and dorsal lobe, on either side, is about the same size ad the lobule dividing the first lateral saddle.

Janenschites, Kabylites, and Baculina are all similar to Bochianites, differing mostly in details of the suture. Janenschites has long, narrow, and more denticulate elements. Kabylites has a larger umbilical lobe, more or less the same size as the 1st lateral lobe. Baculina, which is in doubt, may have been based on a Bochianites that was worn.
