Where to Find Fossils at Coal Point, Isla Vista

Geology: The fossiliferous layers are part of an unnamed Pleistocene formation. Once you park, walk down to the beach and look for the sedimentary rocks on the beach cliff. However, the geology of the area should be similar to the Monterey formation which contains both Gaviota Beach, and Jalama Beach.

Fossils: The layers of sandstone contain marine assemblages from the Pleistocene epoch.
