Taxonomic list
identical to list 8 of Williamson 1996
in a normal paleomag interval that must represent chron 29N because the K-T is in a reversed interval at the base of the section
"Acmeodon secans" of Van Valen 1966 is indeterminate: Williamson and Lucas 1993
type of "Ellipsodon witkoi" Van Valen 1978 is probably NOT Puercan, but provenance is unclear: Williamson and Lucas 1993
