| close to the top of a normal magnetic polarity zone interpreted as C28n, but there is no tie point in the section: see Lucas et al. 1997 | firmly correlated with Wagonroad Upper Horizon, which was included in the list of Tomida and Butler 1980; paleomagnetic data strongly support a correlation between the two horizons descriptions of Robison 1986 do not incorporate the collections reported by Tomida and Butler and Tomida 1982 "Oxyclaenus pearcei" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon Haploconus "inopinatus" is not discussed by Robison 1986 and I assume it is only present at Wagonroad Upper Horizon |

| three UALP localities are separated stratigraphically by five meters: Tomida 1981 near the top of the local section in a normal paleomag interval that is is probably chron 27n but could be chron 28n | called "Upper Kimbetoh" by Tomida 1981 identical to list 12 of Williamson 1996 some records may be from an equivalent level in Betonnie- Tsosie Arroyo list probably omits some multis |

| 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 | |
