Also known as UCMP IP8662

Where: Kern County, California (35.0° N, 118.9° W)

• Paleocoordinates: 40.0° N, 98.1° W (Wright 2013)

• coordinate stated in text

• outcrop-level geographic resolution

When: Liveoak Shale Member (Tejon Formation), Middle Eocene (47.8 - 37.7 Ma)

• Middle Eocene, "Transition Stage" or "Tejon Stage." The co-occurrence of the two species of Ficopsis is suggestive of

•a "Transition" age, F. remondi crescentensis being characteristic of the "Tejon Stage." Turritella uvasana neopleura seems to be characteristic of the lower part of the Liveoak Shale Member and appears to range from the lower part of the "Tejon Stage" downward into the "Transition Stage." The affinities of this assemblage are decidedly with the fauna of the "Tejon Stage" rather than that of the "Domengine Stage."

• bed-level stratigraphic resolution

Environment/lithology: marine; lithology not reported

Size class: macrofossils
