Mesofossils, "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)
