Stratigraphy comments: high in a normal magnetic polarity zone in the Barrel Spring Arroyo = De-na-zin Wash section interpreted as C29n based on the position of the K-T boundary in the section: see Butler et al. 1977, Lucas et al. 1997

Lithology and environment
Primary lithology: | not reported |
Environment: | terrestrial indet. |
Taphonomy
Modes of preservation: | body |
Size of fossils: | macrofossils,mesofossils |
Collection methods and comments
Collection excludes: | some genera |
Reason for describing collection: | taxonomic analysis |
Taxonomic list comments:overlies Ectoconus Zone 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 |
