Near Abiquiu in Rio Arriba County, New Mexico — The American Mountains (Southwest)
— Ghost Ranch —
In June 1947, a field crew led by Edwin H. Colbert from the American Museum of Natural History in New York stopped at Ghost Ranch on their way to Petrified Forest National Monument in Arizona. They knew that Baldwin and other paleontologists had discovered fossils in the area. They soon found fragments of fossilized bone that they recognized were from the small dinosaur, Coelophysis.
Hoping to find a partial skeleton, Colbert and his crew carefully dug into the hillside. Instead of a partial skeleton they found a dense bone bed of hundreds of preserved skeletons. Because the skeletons overlapped each
In 1981 and 1982, field crews from the Carnegie Museum of Natural History in Pittsburgh, and other institutions, collected 15 large blocks from the quarry. In 1983 another large block was excavated by the New Mexico Museum of Natural History. The last block was excavated in 1985 and is on display at the Ruth Hall Museum at Ghost Ranch.

• 1976 – Ghost Ranch’s Coelophysis Quarry was designated a National Natural Landmark by the National Park Service.
• 1981 –The New Mexico State Legislature named Coelophysis the New Mexico State Fossil beating out Brontosaurus.
• 1998 – Coelophysis was the second dinosaur in space when it traveled on NASA's Endeavor Space Shuttle. A Coelophysis skull, quarried at Ghost Ranch, was sent to space by the Carnegie Museum of Natural History. It left Earth on January 22 and returned on January 31.

Also see . . . Wikipedia Entry. “Ghost Ranch was located close to the equator 200 million years ago, and had a warm, monsoon-like climate with heavy seasonal precipitation.
“The multitude of specimens deposited so closely together at Ghost Ranch was probably the result of a flash flood, which swept away a large number of Coelophysis and buried them quickly and simultaneously. In fact, it seems that such flooding was commonplace during this period of the Earth’s history and, indeed, the Petrified Forest of nearby Arizona is the result (Submitted on July 9, 2014.)
