Taxonomic list

• Novacek 1976 and Walsh et al. 1996 both indicate that CIT 314 and UCMP V-6882 are identical
placed in MS-5 (Genessee Avenue) of Walsh et al. 1996
this is a key locality used to support Walsh et al. 1996's argument that the Bridgerian/Uintan boundary is in C21n instead of C20r; this correlation is broadly compatible with 1.97 calibration of 1.96 AEO analysis
