Guide to Finding Fossils at Rincon Point

Directions:

According to this page’s first citation, ” from LA, travel north on the Ventura Freeway (101) towards Ventura. Travel about an hour, north towards Santa Barbara. Exit onto Highway 150 (towards Lake Casitas) and park immediately after leaving Route 101. The fossils are found along the freeway offramp and up the hill above.”

Geology of the Area:

Rincon Point is a famous surfing spot on the border of Santa Barbara and Ventura County. The fossils of Rincon Point are found off a freeway cut that exposes 16 different layers of Santa Barbara Formation strata. Santa Barbara County was underwater for most of Earth’s history, but slowly rose to the surface during the Cenozoic Era, especially as a result of the Miocene dated tectonic movements that created the San Andreas Fault.

Fossils:

Pliocene-Pleistocene dated fossils are abundant in the sediments off the freeway. The fossils are marine fauna including invertebrates such as bryozoa, mollusks, gastropods, and Pecten.

Where to Find Fossils in Jack’s Peak County Park

Geology: According to the USGS, “Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history“, meaning that it is difficult to easily date the fossils based on location. See the Further Reading to learn more about the geology of the Monterey Bay region.

Fossils: Fossils containing small leaves and shells are in shale a hundred yards down the trail from the west parking lot.

Guide to Finding Fossils at Topanga Canyon

Geology:

Topanga Canyon is part of the Topanga Canyon Formation. It contains middle Miocene sandstone and siltstone.

Paleontology:

The sediments contain large quantities of gastropods and pelecypods (most are shell prints). It is recommended to go after a rain when the fossils have been washed (at least partially) out of the matrix.

Directions: 

“from the Ventura Freeway (in the San Fernando Valley), get off at the Valley Circle/Mulholland Drive exit Turn left onto Valley Circle, cross over the freeway and proceed onto Mulholland Drive. Turn right onto Valmar Avenue — Valmar becomes Old Topanga Canyon Road. At Mulholland Highway, bear right and prepare to turn left back onto Old Topanga Canyon Road in 1/8 mile. Turn left and proceed up Old Topanga almost a mile, past the point where the road switches back upon itself. From this point until the top of the hill, you will encounter fossiliferous road cuts on your right. The first embankment contains a massive oyster reef.” (see first citation for source)

Where to Find Fossils at Centerville Beach

Geology of the Area: Centerville Beach is part of the Rio Dell Formation, giving it very similar geological history to the Scotia Bluffs nearby. The sedimentary rocks were once a mud rich layer that was deposited on the edges of a shallow sea during the Pleistocene epoch. Look for layers of grey unconsolidated mud, which will be fossiliferous and have shell fossils protruding from the surface. Low tide is the best time to look for fossils on a beach.

Paleontology/ Fossils Found: Moon Snail, Giant Pacific Scallop, Clam, Pandora shell, Cockle, Snail, Channeled Dogwinkle, and other fossils can be easily found on the cliffside of the beach.
