Taxonomic list

• original section provided by these authors is severely inconsistent with section of Pajak et al. 1996, with multiple localities appearing in reversed order and a majority of localities in each section not duplicated; furthermore, Pajak et al.'s section appears to be based on biochronological assumptions and even the authors state that "Some localities may overlap in both time and stratigraphic position"; therefore, no formal section is used here
"unnamed sandstone" Fm. underlies the Pauba Formation and may be younger than the Temecula Arkose, but there is no direct superposition between the two older units
all of the California Oaks localities are said to be late Blancan or early Irvingtonian
locality not discussed by Pajak et al. 1996
