Age. Blancan and Irvingtonian (Pajak et al. 1996).
General Description.There are three formations within the Elsinore Fault Zone that are fossiliferous (Pajak et al. 1996): the older Temecula Arkose appears to be pre-Pleistocene. Above this, the unnamed sandstone includes three informal faunal components: the Paraneotoma unit estimated at ±3.5 mya to 2.2 ± 0.1; and the Mimomys unit (± 1.6 to ± 0.75 mya. Stratigraphically above the unnamed sandstone, the Pauba Formation is late Irvingtonian at <0.6 to >0.12 mya.
The fauna from the Paraneotoma unit is included here but not mapped on the taxon accounts since much, or possibly all, may be pre-Pleistocene. The other units are listed in the taxon accounts as Elsinore: Mimomys, Elsinore: Microtus/Mammuthus, and Elsinore: Pauba.
Pajak et al. (1996) list taxa from a fairly large number of sites; I have included only taxa from sites noted as belonging to specific units.
