A 1 to 3 foot thick fossiliferous marine deposit exposed along the coastal bluffs above Devereux Beach from the foot of Camino Majorca Road, in Isla Vista, Santa Barbara County, California, USA, west to Coal Oil Point. The deposit rests with sharp angular unconformity on a marine terrace 7 to 20 feet above the modern beach and eroded into the underlying, north-northeastward dipping diatomaceous shale of the Pliocene Sisquoc Formation.
The assemblage includes at least 86 invertebrate species. Mollusks are most common, comprising 63 species.
A thin bed (up to two inches thick) of tar [pyrobitumen] occurs near the center of the deposit (evidence of late Pleistocene tar seeps offshore). The deposit appears to grade upward into the overlying alluvium-colluvium.
