| said by Buckley 1993 to be in the same (unidentified) reversed polarity chron as Silberling Quarry, i.e., possibly C27r | many of the types were described by Simpson 1935d Simpson 1935d lists the type of "Chriacus pusillus" from "Gidley or Silberling Quarries" - no other specimens are listed but the type's catalogue number is close to that of other types from Gidley Quarry; however, this record is omitted by Simpson 1937a and later authors |

| 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 | ||||
