Scarce remains of bats are reported from five localities in northern Nebraska in which other kinds of vertebrates are much more common. ?Oligomyotis or ?Myotis, possibly of an undescribed species, is represented by fragments of jaws and humeri from an early Arikareean (late Oligocene) locality in Dawes County. Several toothless jaw fragments from the late Hemingfordian (middle Miocene) Companion Quarry in Sioux County represent an indeterminate microchiropteran. An indeterminate species of Myotis was encountered in the middle Clarendonian (late Miocene) Ashfall site in Antelope County. A hairy-tailed bat, Lasiurus sp. indet., occurred in late Clarendonian (late Miocene) and late Blancan (late Pliocene) sites in Brown and Antelope counties, respectively. The Clarendonian record for Lasiurus represents the earliest documented occurrence of the genus.
