Also known as Locality BS-1
Where: Orange County, California (33.8° N, 117.7° W: paleocoordinates 39.4° N, 87.1° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Holz Shale Member (Ladd Formation), Campanian (83.6 - 72.1 Ma)
• from "about 1 m of strata"
• group of beds-level stratigraphic resolution
Environment/lithology: lagoonal; lithified siltstone and lithified shale
•the Holz Shale in general is "in a shallow marine setting, including prodelta, lagoonal and bay environments"
•apparently well lithified because strata were "broken" and "disarticulated" during collection
Size class: macrofossils
Collection methods: surface (in situ),
• "selective collecting, by breaking the strata at the site"
•collections apparently are at the California State University at Fullerton
