The La Brea Tar Pits and Hancock Park are situated within what was once the Mexican land grant of Rancho La Brea, now part of urban Los Angeles in the Miracle Mile district. For some years, tar-covered bones were found on the Rancho La Brea property, but were not initially recognized as fossils because the ranch had lost various animals–including horses, cattle, dogs, and even camels–whose bones closely resemble several of the fossil species. The original Rancho La Brea land grant stipulated that the tar pits be open to the public for the use of the local Pueblo. Initially, they mistook the bones in the pits for the remains of pronghorn ("Antilocapra americana") or cattle that had become mired.
