The Cerutti Mastodon site is a paleontological and possible archeological site in San Diego County, California. In 2017, broken mastodon bones at the site were dated to around 130,700 years ago. The bones were found with cobblestones displaying use-wear and impact marks among the otherwise fine-grain sands.

The Vaqueros Formation is a sedimentary geologic unit primarily of Upper Oligocene and Lower Miocene age, which is widespread on the California coast and coastal ranges in approximately the southern half of the state. It is predominantly a medium-grained sandstone unit, deposited in a shallow marine environment.
The stone tools of these industries, along with preforms, lithic core, technical flakes, and pieces of angular debitage, mainly of chalcedony, are found on and in late middle Pleistocene-age fanglomerates and younger inset alluvial terraces in the Calico Hills (also known as the Yermo Hills) east of the Calico Peaks and the Calico Mountains.
The fossils include unique species of fish that had never been found in the area before. The discovery is reshaping views on California geology with the possibility of extinct islands.
