Taxonomic list
• type section dated at 14.77 +/- 0.23 Ma (Ar-Ar) "above the vertebrate localities": Downing and Swisher 1993; fm. dated elsewhere (?) at 16.7 (= 17.14) Ma by Evernden and James 1964 (KA 1285), who report that the original fauna's stratigraphic position is unclear; ash near top of section dated at 14.93 +/- 0.08 Ma (Ar/Ar) by Perkins et al. 1998, and this date seems preferable
