| Taxonomic list comments: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 "Mt. Blanco" material of uncertain provenance: Glyptotherium texanum type Osborn 1903 Platygonus "texanus" type Gidley 1903 Rhynchotherium falconeri type Osborn 1923: Cope collection Stegomastodon "texanus" type Osborn 1924b | |||
