Unexpected find

Construction for a new subway expansion in Los Angeles has yielded several treasures for paleontologists. In April 2017, workers came across the bones of an ancient camel and a Probiscidean, such as a mammoth or a mastodon, just months after workers unearthed the skull of a large Probiscidean in November 2016.

The paleontologists carefully dusted off the mammoth or mastodon skull in order to safely take it from the ground. Workers recently discovered the bones while digging a new subway tunnel for the Los Angeles Metro in November 2016.

Plastering bones

Once the bones were excavated, paleontologists quickly plastered the bones to protect them. They will eventually be housed at the Los Angeles County Museum for Natural History.
