Taxonomic list

• Nations et al. 1981 show that this is about 14 mi W of House Mountain and of uncertain stratigraphic position relative to that section
decent paleomag lower in section, but fauna is from interval that is "poorly magnetized" and correlation is completely ambiguous, contra Lindsay et al. 1984
Stegomastodon mirificus specimen of Agenbroad et al. 1998 is from "Clarkdale" in the upper Verde Fm., Yavapai Co.
NISP about 58
