• coordinate based on nearby landmark

• local area-level geographic resolution

When: Ten Mile Member (Chico Formation), Early/Lower Campanian (83.5 - 70.6 Ma)

• No lithostratigraphic unit assigned to taxon mentioned in text. Similar to material from Texas Flat mine shaft collection of the same age. Is listed as early Campanian. From Squires amd Saul (2002): "The stratigraphically highest strata of the Chico Formation exposed along Big Chico and Butte creeks constitute the Ten Mile Member of Saul (1959, 1961), which was formalized by Haggart and Ward (1984) . This silty sandstone member ranges from Santonian to lower Campanian, and the relevant fossils included in this report are from the part recognized by Saul (1959) as lower Campanian

• member-level stratigraphic resolution

Environment/lithology: offshore; shelly/skeletal, silty sandstone
