The stratigraphic position of the bone concentration in relation to the total Nacimiento section exposed in Kutz Canyon has not been determined. It is approximately 160 feet below the western rim at a point nearest the "pocket". The upper 100 feet of strata consists of sandstone believed by Granger (1917:822) to represent either: (1) equivalent of the "Wasatch" (San José) of the Ojo Alamo section, or (2) "Torrejon" (upper Nacimiento). Granger perhaps favored the first interpretation, but the writer, at present, thinks the second probable.

ANGELS PEAK CENSUS
The total number of specimens for each member (species or genus) of the faunule is tabulated in the list on the page facing, page 7. For the purposes of this list, census, a few of the isolated teeth have been counted as jaws. They were so counted whenever they seemed to be representative of separate, individual animals.
The census-count includes all of the specimens that were identified. The numbers in parentheses, on page 7, refer to those individuals that were found outside of the 100 linear yards or so of outcrop comprising the principal area of concentration of specimens.
