''Procaimanoidea'' ("Before Caiman-forms") is an extinct genus of alligatorid from the Eocene of North America. It was named posthumously in 1946 by Charles W. Gilmore; the type species is ''P. utahensis'', from the Uintan (middle Eocene) of Utah. It is based on USNM 15996, a nearly complete skull and partial left hind leg. A second species, ''P. kayi'', was named in 1941 by C.C. Mook as a species of ''Hassiacosuchus'', for remains from the Bridgerian (early Eocene) of Wyoming. It was reassigned to ''Procaimanoidea'' in 1967 by Wassersug and Hecht. ''Procaimanoidea'' was a small alligatorid, and slightly heterodont, the last four teeth on each side of the jaws having blunt tips.〔 ==References==
