Geological history of Point Lobos of waves and rain that cause erosion of the others type of rocks. The age of this kind of rocks varies from ten thousand years ago up to the present day. Geological history of Point Lobos The geological history of Point Lobos, regarding the Point Lobos headland on the Central Coast in Monterey County, California|Monterey County]], California. The area's geology encompasses the last 80 million years. The oldest rocks exposed here were formed during the Cretaceous Period of the Mesozoic Era, when the dinosaurs still roamed the earth and pterodactyls dominated the sky. The area forms part of the Salinian
Cretaceous local subdivisions are still in use. As with other older geologic periods, the rock beds of the Cretaceous are well identified but the exact age of the system's base is uncertain by a few million years. No great extinction or burst of diversity separates the Cretaceous from the Jurassic. However, the top of the system is sharply defined, being placed at an iridium-rich layer found worldwide that is believed to be associated with the Chicxulub impact crater, with its boundaries circumscribing parts of the Yucatán Peninsula and into the Gulf of Mexico. This layer has been dated at 66.043 Ma.
