LA Subway Dig Uncovers Prehistoric Artifacts

LOS ANGELES (AP) — Scientists have long known that years before hipsters and tourists were trekking along Los Angeles' Miracle Mile dinosaurs were doing so.

Now, thanks to a subway dig, they're discovering that sea lions may have swam there too.

The Los Angeles Times reports that an exploratory subway shaft dug down the street from the La Brea Tar Pits has uncovered a treasure trove of other prehistoric artifacts in the land where dinosaurs roamed.

They include mollusks, asphalt-saturated sand dollars and possibly the mouth of a sea lion.

The sea creatures' residency dates back millions of years, to a time when the Pacific Ocean extended several miles farther inland.

The shaft was dug ahead of work scheduled next year to extend a subway line across LA's West side.
