Medicine Rocks Site 1 "from six small wind-deflation pockets" near Ekalaka, in SE 1/4 SW 1/4 sec 2 T3N R58E (Estes 1976) Danian

Fort Union Medicine Rocks I
Kommentar z. Stratigraphie Lithographie Kommentar z. Taxonomie
"The Medicine Rocks Sandstone, a unit that was originally mapped as part of the Tongue River Member of the Fort Union Formation. More recent work, however, has shown that the Medicine Rocks Sandstone is bounded by unconformities and it has thus been designated as its own unit, now called the Ekalaka Member of the Fort Union Formation YPM PU 16781 is from “Locality 1,” which Sloan (1970) grouped with other localities into an assemblage named Medicine Rocks I. A tentative Torrejonian 3 age is typically given on the basis of the mammalian assemblage found at that site (e.g., Lofgren et al. 2004)" (Joyce et al. 2009) "sandstone" (Estes 1976) said to be To3
several other localities in this area are Tiffanian
Site III and Mehling Site are "at essentially the same stratigraphic level": Krause 1987a
possibly relevant: Pantolambda bathmodon Simons 1960: "probably occurs in the Medicine Rocks local fauna" Pantolambda cavirictum Simons 1960: "Medicine Rock local fauna"

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

in a stratigraphically isolated reversed polarity zone interpreted as chron 27r: Butler et al. 1987 >I have used Van Valen's 1978 list of condylarths because Rose gives no reason for ignoring it
meter level follows Butler et al. 1981
above two records presumably include "Tricentes cf. punitor" and "cf. Chriacus sp."
