Collection methods and comments
| Reason for describing collection: | biostratigraphic analysis |
| Taxonomic list comments:"Aelurodon taxoides" Wang et al. 1999: supposedly reworked specimen "Leptocyon cf. vafer" of Cook and Macdonald 1962 seems extremely unlikely as there are no other Hemphillian or even Clarendonian records of this genus; however, Skinner et al. state that the type is from the Johnson Mbr., as is the type of "Tomarctus propter" | |
