Bone fragment from ancient 1,500-pound ground sloth unearthed beneath Crenshaw Boulevard

For the third time in six months, crews working on a Los Angeles rail system expansion have unearthed fossils of beasts that roamed the Southland many millennia ago.

On May 16, crews working on Metro’s Crenshaw line found a fragment of a bison bone and the hip joint of an ancient sloth 16 feet below Crenshaw Boulevard, officials said on Metro’s blog.

The specimens were stabilized and prepared in a lab and formally identified by a scientist at the La Brea Tar Pits and Museum on May 24.

In April, crews working on the Purple Line expansion under Wilshire Boulevard found bones from an ancient camel and mammoth or mastodon. In November, the partial skull and tusk of a mastodon was also found under the Purple Line.

The bones found under Crenshaw Boulevard will eventually be transferred to the Natural History Museum of Los Angeles County or another site accredited for permanent curation, Metro officials said.
