Earth-movers are diverted, and Leger gets on her hands and knees and gently brushes the dirt from a spot pointed out by a member of her team'It's an absolute dream come true for me,' said Leger, who spent the previous decade at a South Dakota mammoth site with no discoveries even close to the size of the one in Los Angeles. subway digs beginning in the 1990s, when work started on the city's inaugural line, said Dave Sotero, spokesman for the Los Angeles County Metropolitan Transportation Authority.
'It's the one fossil you always want to find in your career.'California's stringent environmental laws require scientists to be on hand at certain construction sites. Paying for the paleontologist staff from Cogstone Resource Management is factored into the project's cost, he said.

Her heart beats faster because there's a chance she'll uncover what she calls 'the big find.'A skull of a young Columbian mammoth found at the construction site of the Metro Purple Line extension is placed on a cart at the La Brea Tar Pits and Museum in Los Angeles.
