Stratigraphy
Formation:Nacimiento
Local section:Barrl Local bed:4
Local order:bottom to top
Stratigraphic resolution:member
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
