Where Early Dinosaurs Lived, Deal Expands a National Park

Excerpts:

The National Park Service will sign a deal Thursday greatly expanding the boundaries of Petrified Forest National Park in northeast Arizona, where relatively small bipedal dinosaurs roamed hundreds of millions of years ago and their fossilized remains have been discovered in the stark, rainbow-hued landscape...

Part of the Painted Desert, it was originally set aside for protection in 1906 by President Theodore Roosevelt, who established the Petrified Forest National Monument. The land, east of Holbrook, Ariz., and straddling Interstate 40, became a national park in 1962 and, until this deal, included 109,000 acres.
