| Big Pocket | NW 1/4 sec 14 T27N R11W, Kutz Canyon "Almost all the material was recovered from approximately 100 linear yards of outcrop" (Wilson 1951) | Danian zwischen 61.7 und 63.3 Millionen Jahren |
Nacimiento | Angels Peak; KUVP Loc. 13; Locality NM 13; NMMNH 2635; UALP 7435, 7436, 75144; NMMNH locality L-2635 |

| from "a zone... three to four feet in thickness... The actual bone layer, not as yet located, may prove to be thinner than this" (Wilson 1951) not far below the middle of a reversed magnetic polarity zone in the Kutz Canyon section interpreted as C27r based on the position of the K-T boundary in the correlative Barrel Spring Arroyo = De-na-zin Wash section: see Butler et al. 1977, Lucas et al. 1997 | "reddish silt" (Wilson 1951) | UALP localities are at exactly the same level as KUVP 13 but may be at some distance following taxa listed by Williamson and Lucas may be from Big Pocket or a stratigraphically nearby locality: ? Peradectes sp. "D" Pentacodon inversus Protictis haydenianus "Protictis" sp. "A" Protictis (Protictis) sp. "B" Triisodon quivirensis Ellipsodon inaequidens | ||

| 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 |

| West Flank Torreon Wash (Pantolambda Zone) | Danian zwischen 61.7 und 63.3 Millionen Jahren |
Nacimiento | Sinclair and Granger Loc. 10 (in part); Torreon Wash Pantolambda Zone (in part); UCMP 87141, 87142; BUNM-77-184, -77-199a; NMMNH L-01287 | |

| identical to list 26 of Williamson 1996 presumably includes BUNM-77-183 of Tsentas 1981 clearly includes list of Tsentas 1981, despite lack of explicit discussion; includes all Pantolambda Zone taxa mentioned by Lindsay et al. 1978, 1981 two BUNM sites are the same although Williamson 1996 reports specimen counts for Tsentas Quarry, these apply only to therians normal polarity, correlated with 27N on basis of biochronology, but there is no independent tie point |

| this is NOT West Side of Shotgun Butte (see), which is the uppermost of three fossiliferous horizons; the fauna of the lowest horizon is not discussed by Gunnell apart from the plesiadapiforms, Gunnell's list is mostly repeated from ancient sources without modification Gunnell lists Eudaemonema cuspidata from "Shotgun fauna, Keefer Hill" but omits this from his faunal list | ||||
