| | ABSTRACT: | A paleontologic investigation employing wet screening and heavy liquid separation of rock samples from the lower and middle members of the continental Sespe Formation at the Simi Valley Landfill, Ventura County, California, is yielding large superposed samples of middle Eocene microvertebrates. This report documents the first records of identifiable mammals ("Peratherium" sp. undet, Sespedectes singularis, Simimys sp. undet.) from the lower member and the first records of Parasauromalus sp. undet; cf. Tinosaurus sp. indet; Paleoxantusia sp., cf. P. allisoni; melanosaurine anguids; cf. Batodonoides powayensis; Centetodon sp., cf. C. aztecus; "Namatomys" sp., cf. "N". fantastna; "Namatomys" n. sp.; Paradjidaumo n. sp.; Heliscomys n. sp.; Simimys n. sp.; Zapodidae?, n. gen. and sp.; Miacis sp. undet; Simimeryx n. sp.; and an indeterminate camelid from the middle member. A new local fauna, the Simi Valley Landfill Local Fauna of middle or late Duchesnean age, is recognized in the middle member, and lies stratigraphically higher than the Pearson Ranch Local Fauna.
