Unnumbered Johnson Spring Locality of Davis 5 | Ross D. C. (1966) | Johnson Spring | "R. J. Ross, Jr. (written commun., 1962), placed the Johnson Spring Formation in the Wilderness Stage (immediately below the Trenton) of the Middle Ordovician. Langenheim and others (1956, p. 2093) considered that the "fauna has a general Blackriver-Trentonian aspect," but they seemed to favor a Trenton age. Pestana (1960, p. 864) also favored a Trenton age. The Johnson Spring Formation is thus considered Middle Ordovician, most probably middle or late Middle Ordovician." | not reported | 470 - 458.4 Ma Middle Ordovician |
