Where: Kern County, California (34.9° N, 118.8° W: paleocoordinates 34.5° N, 106.9° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Tejon Formation, Bartonian (41.3 - 38.0 Ma)

• From upper Tejon Formation, and most likely from "Tejon" stage, or possibly the "Transition" stage. Therefore a upper Middle Eocene=Narizian=Bartonian age is assigned to the collection, although it is possibly as old as Lutetian. The Tejon Formation unconformably overlies basement, and is unconformably overlain by the Tecuya Formation (Oligocene) in this section. About 75 m stratigraphically below top of undivided Tejon Formation. It is not specified which member of the Tejon Formation the collection is derrived.

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; lithified, silty, carbonaceous sandstone

Size class: macrofossils

Reposited in the USGS

Collection methods: quarrying,

• Collected by T.H. Nilson and W.O. Addicott. Collections likely to be reposited at USGS Menlo Park or USNM (not specified).
