Collection methods and comments
| Reason for describing collection: | taxonomic analysis |
| Museum repositories: | UCMP |
| Taxonomic list comments:based on Lofgren et al. 1990 and Lofgren 1995, fauna is mixed; I have sorted out Paleocene and reworked Cretaceous lists based on Lofgren's scheme "Purgatorius ceratops" type: only a single tooth; Johnston and Fox 1984, Fox 1990, and Buckley 1997 all question this record on the grounds that it is probably a contaminant in the screenwash sample; Van Valen 1994 disagrees | |
