| this is NOT West Side of Shotgun Butte (see), which is the uppermost of three fossiliferous horizons; the fauna of the lowest horizon is not discussed by Gunnell apart from the plesiadapiforms, Gunnell's list is mostly repeated from ancient sources without modification Gunnell lists Eudaemonema cuspidata from "Shotgun fauna, Keefer Hill" but omits this from his faunal list | ||||
