Taxonomic list

• Blanco Ash above main fossiliferous unit dated at 2.8 +/- 0.3 Ma (FT on glass) and entire section is reversed up to the Guaje Ash in the overlying Blackwater Draw Fm., dated at 1.4 +/- 0.2 Ma (FT on glass), which is most compatible with a lower Matuyama age: Schultz 1990a; this spans 1.98 to 2.60 Ma in the Cande and Kent 1992 time scale, which is already quite inexact and fails to include the FT date, a presumable underestimate
NISP 184 plus perhaps a dozen
