Where: Yolo County, California (38.5° N, 122.1° W: paleocoordinates 42.7° N, 86.6° W)

• outcrop-level geographic resolution

When: Funks Formation, Coniacian (89.8 - 86.3 Ma)

• STRATIGRAPHIC RELATIONS: From the Funks Fm, which overlies the Sites Fm, and below the "cannonball", a lateral equivalent of the Guinda Fm. AGE: Coniacian, or possibly Santonian, on the basis of foraminiferal biostratigraphy and questionable correlation to better dated sections. STRATIGRAPHIC POSITION: From the lower part of the formation.

• bed-level stratigraphic resolution

Environment/lithology: marine; lithified shale

Size class: macrofossils

Preservation: mold/impression
