| Museum repositories: | SDSM |
| Taxonomic list comments:"In heavy Miocene channel deposits" and nothing further is said about the stratigraphic position, although it is close to the Sharps localities; but Tedford et al. 1996 say it is a lateral equivalent of SDSM V-5410 possibly relevant: Archaeocyon pavidus Wang et al. 1999: "LACM loc. 1973, Godsell Ranch" NISP 9 (est.) Martin 1986 list the type of Leidymys ("Eumys") blacki as from SDSM V-5362; no other specimens from V-5410 have been referred to L. blacki contra Tedford et al. 1996 | |
