Workers digging a tunnel for a new railway line in Los Angeles stumbled upon a unique discovery: the fossils of a giant sloth and bison from thousands of years ago, according to BBC. The "amazing discovery" of a sloth's hip bone and fragments of a bison's radius bone were found 16 feet under ground in Park Mesa Heights.
Both species have been extinct for at least 10,000 years.

According to scientists, the Harlan Ground Sloth could have weight up to 1,500 pounds, and measured 10 feet in length.
The bison and the sloth likely roamed the Earth in the late Pleistocene area. That's anywhere from 11,000 to 40,000 years ago
The discovery, which was made May 16, took scientists eight days to identify the remains, which are now located at the La Brea Tar Pits and Museum.
