Taxonomic list

• Garbani 13 and 14 are virtually the same locality: Simmons 1987
between W- and Y-Coals: Swisher et al. 1993
W-Coal dated at 64.11 +/- 0.02 Ma AA, which seems to be a useable estimate because the fauna is in a deep channel that cuts into the underlying Y-Coal. Reported to be Pu2-3 by Clemens (2006).
