Palatobaena is an extinct genus of baenid turtle. 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.[2] The two other species are P. gaffneyi (a complete skull from Eocene (Wasatchian North American Land Mammal Age))[3] and P. cohen which existed in Hell Creek Formation, North Dakota during the late Cretaceous period (Maastrichtian age).[4]
