| 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: ?
