Taxonomic list
• "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"
