Plant matter found at the site in the arid San Timoteo Canyon, 85 miles (137km) south-east of Los Angeles, showed it was once much greener.
The bones will go on display next year.
The find is a million years older than the famous haul from the tar pits at Rancho La Brea in Los Angeles, said Rick Greenwood, a microbiologist and also director of corporate environment health and safety for Southern California Edison.
"If you step back, this is just a huge find," he said. "Everyone talks about the La Brea Tar Pits, but I think this is going to be much larger in terms of its scientific value to the research community."
The number of skeletons found at the site may be explained by a marsh or lake bed that trapped animals looking for water, leaving them victim to predators, palaeontologists think....
