In California, on a substation building site, 1500 bone fragments (1.4 millions years old) have been found. Included in this find is sabre-toothed tiger remains and tons of other animal remains. Also tons of plant matter.
In fact, the number of skeletons found at the site could indicate that a marsh or a lake bed could have existed, trapping animals looking for water, leaving them vulnerable to predators. A paleontologist said that the find wasn't directly comparable to Le Brea, as it consisted of different species from another era. However, he did say it would definitely be valuable.
