| Local order: | bottom to top | ||||
| Stratigraphic resolution: | member | ||||
| Stratigraphy comments: low 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
| Environment: | terrestrial indet. |
Taphonomy
| Modes of preservation: | body |
Collection methods and comments
| Collection excludes: | some genera |
| Reason for describing collection: | general faunal/floral analysis |
| Taxonomic list comments:multiple records omitted by Williamson and Lucas 1993 identical to list 7 of Williamson 1996 underlies Taeniolabis Zone 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 | |
