Also known as Lillis Ranch

Where: Fresno County, California (36.4° N, 120.4° W: paleocoordinates 39.0° N, 103.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Cerros Shale Member (Lodo Formation), Ypresian (56.0 - 47.8 Ma)

• Assigned to the "Arroyo Hondo" formation (lower part of the "Capay Stage") by Vokes (1939) and Miller & Downs (1950), but the Lodo Formation is now used for this unit. Calcareous nannofossils indicate the CP10 (Tribrachiatus orthostylus) zone of early Eocene age and the transition between the CP10-CP11 (Discoaster lodoensis) zones, according to Squires (1988).

• group of beds-level stratigraphic resolution

Environment/lithology: deep-water; lithified shale

Size class: macrofossils

Reposited in the UCMP
