| Stratigraphy comments: low in a reversed magnetic polarity zone correlated with the Barrel Spring Arroyo = De-na-zin Wash section interpreted as C28r based on the position of the K-T boundary in that 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
| Reason for describing collection: | general faunal/floral analysis |
| Taxonomic list comments:above Head of Barrel Spring Arroyo identical to list 10 of Williamson 1996 list of Williamson and Lucas 1997 repeats a subset of earlier list I suspect this is on the divide between Gallegos Canyon and De-Na-Zin wash because it is referred to by both names by Williamson 1996 just above part of local section of known paleomag polarity omits multis | |
