ammonites
UCLA Loc. 2415 - El Toro (Cretaceous of the United States)

Where: Orange County, California (33.6° N, 117.7° W: paleocoordinates 39.4° N, 87.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Late/Upper Campanian (83.5 - 70.6 Ma)

• STRATIGRAPHIC RELATIONS: From unknown lithostratigraphic unit; possibly a correlative or slightly younger of Pleasants Sandstone. AGE: Highest Campanian or possibly lowest Maastrichtian, on the basis of ammonite biostratigraphy. Here assigned to the Campanian to avoid stratigraphic orphaning. STRATIGRAPHIC POSITION: From unknown position in local stratigraphic section.

• bed-level stratigraphic resolution

Environment/lithology: coastal; lithified sandstone

• ENVIRONMENT: No environmental reported. Presumably shallow-water siliciclastic marine.
• SPECIFIC LITHOLOGY: Sandstone. LITHIFICATION: Lithified, on the basis of figured specimens.

Size class: macrofossils

Preservation: cast, mold/impression

Collected by Saul in 1949
