Collection methods and comments
| Taxonomic list comments:upper Mbr. 3 and lower Mbr. 4; = most of "C. avawatz./ P. furlongi" zone, except part that ranges into upper Mbr. 4 ash at 410 m, close to the base of the upper faunal zone, dated at 11.8 +/- 0.9 Ma (FT on zircon); this date is considered acceptable by Perkins et al. 1998 and seems as useable as any other for this faunal zone |
