This report is on three ammonoids from the type section of the Mankomen Formation. Two of them are medlicottids, apparently representing the same species; both are fragments of the body chamber. The other is a paragastrioceratid having the external suture preserved but lacking the surface features. Unfortunately, positive identification even as to genus generally is based on the suture together with the surface ornamentation and shape of the shell. Tentatively I would identify these fragmental fossils as follows: (see list by locality)
