| 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 | reversed polarity, as is most of section, but correlation to chron 27R is based strictly on biochronology |

| LACM | records of Williamson and Lucas 1993 could include some material from Betonnie-Tsosie Arroyo identical to list 13 of Williamson 1996 entire section is of reversed polarity according to Taylor 1981 type of Ellipsodon "yotankae" appears to be from Sinclair and Granger Locality 8; see Van Valen 1978 partial list of Taylor 1981 is repeated from Wilson almost without modification but includes Triisodon; this might be a lapsus as the KUVP 13 record of Triisodon appears in an adjacent column of Wilson's table paleomag correlation is based on entirely reversed polarity of local section, but there is no tie point and the correlation is completely ambiguous |

| 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 |
