Also known as Locality 4
Where: Orange County, California (33.8° N, 117.7° W: paleocoordinates 34.7° N, 81.4° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Holz Shale Member (Ladd Formation), Turonian (93.9 - 89.8 Ma)
• from "about 1 m of strata"
• group of beds-level stratigraphic resolution
Environment/lithology: prodelta; 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: bulk, surface (in situ),
• "Bulk samples were collected... and brought back to the lab for disarticulation" but there was also "selective collecting, by breaking the strata at the site"
•collections apparently are at the California State University at Fullerton
