Also known as Locality 4 of Waring 1917; CAS loc. 61667; CAS loc. 61901; CAS loc. 61926; LSJU 4; LSJU loc. 2697
Where: Ventura County, California (34.2° N, 118.7° W: paleocoordinates 39.2° N, 96.7° W)
• coordinate estimated from map
When: Las Virgenes Formation, Danian (66.0 - 61.6 Ma)
• Originally described as "Martinez," but now belongs to Santa Susana Formation. Nautilids come from Zinsmeister's (1983) "assemblage A" which spans the lower three-quarters of the Santa Susana. Planktonic foraminifera suggest a P4 and P5 age (Heitman, 1983) and calcareous nannoplankton belong to zones CP5-CP8 (Filewicz & Hill, 1983), indicating a Thanetian age.
•
•[Squires 2018] Waring (1917) listed the mollusks found at this locality and referred to them erroneously as ‘Martinez’ species of ‘early Eocene’ age. The type locality of O. plectata plots in upper lower Paleocene (upper Danian Stage) strata mapped as the Las Virgenes Sandstone (Squires, 1981).
Environment/lithology: transition zone or lower shoreface; bioturbated, fine-grained sandstone
Size classes: macrofossils, mesofossils
