LACMIP loc. 10889, Harding Creek (Cretaceous of the United States)

Where: Orange County, California (33.7° N, 117.6° W: paleocoordinates 34.7° N, 81.3° W)

When: Baker Canyon Member (Ladd Formation), Turonian (93.9 - 89.8 Ma)

• Ladd Formation, Baker Canyon Member. Age: Turonian.

Environment/lithology: shallow subtidal; sandstone

• "The strata...were deposited along a shoreline in warm, very shallow sublittoral water (Saul, 1982). The sedimentological details of the Baker Canyon Member indicate a fluctuating, moderate to high-energy, lower to upper shoreface paleoenvironment associated with a fan-delta setting (Cooper et al.1982)"
• "fossiliferous sandstone overlaying the gray basal conglomerate"

Size class: macrofossils

Collected by W. P. Popenoe in August, 1929; reposited in the LACM
