Palatobaena is an extinct genus of baenid

. It was first named by Gaffney in 1972 and the type species is Palatobaena bairdi. It based on a fragmentary skull from the Fort Union Formation
of the Bighorn Basin
of Wyoming
. The two other species are P. gaffneyi (a complete skull from Eocene (Wasatchian
North American Land Mammal Age)) and P. cohen which existed in Hell Creek Formation
, North Dakota
during the late Cretaceous
period (Maastrichtian
