Cerutti Mastodon site, Paleontological site in San Diego, United States.
The site contains mastodon bones, stone tools, and over 300 bone fragments found during a freeway expansion project in 1992.
Uranium-thorium dating revealed that the mastodon remains and associated artifacts at the site date back approximately 130,700 years.
The San Diego Natural History Museum exhibits findings from the site, presenting evidence of potential early human presence in North America.
Researchers continue to analyze bone fragments and stone artifacts at the site through advanced scientific methods and laboratory examination.
The discovery includes five cobblestones with impact marks and bone residues, suggesting deliberate processing of mastodon remains by early humans.
