Fernando Formation

Fernando Formation
Stratigraphic range: Pliocene epoch,
Neogene period
Type Geologic formation
Underlies Pico Formation
Location
Region Los Angeles Basin, Santa Monica Mountains
Los Angeles County, California
Country United States

The Fernando Formation is a Pliocene stratigraphic unit and geologic formation in the greater Los Angeles Basin and Santa Monica Mountains, in Los Angeles County of Southern California.

Geology

Outcrops of the formation in Santa Monica Mountains National Recreation Area have produced fossil shark teeth.[1][2]

Classification

The underlying Repetto Formation is equivalent in age to the Fernando Formation, and some researchers consider it as well as the overlying Pico Formation to be a junior synonym based on benthic foraminifera stages.[3] Other researchers maintain that the Repetto and Pico Formations are distinct stratigraphic units, and that the use of the name "Fernando Formation" should be stopped due to several issues with stratigraphic correlation and access to the type section.[4]
