believed to be Puercan or Torrejonian by McKenna et al., but "definitely Tiffanian" according to McKenna and Lofgren 2003 from "near the base of information member 4b (formerly Tgsu)" Lofgren et al. 2014: The mammalian fauna from member 4a and the lower part of member 4b is collectively referred to as the Goler Assemblage. the Goler Assemblage is probably middle Tiffanian (Ti3–Ti4a), although a Ti5a age is also possible. formation is "non-marine and then marine" going up section, and consists of "Almost 4 km of conglomerates, feldspathic sandstones, and drab or variegated mudstones" UCMP material of Lofgren et al. 1999 is from "Laudate" but these authors do include Black Mountain in the fauna
