Ghost Ranch in Abiquiu is known worldwide among paleontologists as the location of the articulated fossils of the Coelophysis (SEE-Low-FY-sis), as well as having one of the richest quarries of the Triassic era, which began 220 million years ago. The museum is named for amateur paleontologist Ruth Hall, wife of first resident Ghost Ranch Director Jim Hall. Displays range from a complete Coelophysis cast skeleton to remains from great alligator-like reptiles. The Coelophysis also has the distinction of being named the State Fossil of New Mexico.
Two little dinosaurs, discovered at Ghost Ranch decades apart, form the centerpiece of the research and exhibits at the Ruth Hall Museum of Paleontology. The bones of the Coelophysis (SEE-low-FY-sis), who roamed the ranch 220 million years ago, were discovered in 1947. Six decades later in 2009, the Tawa Hallae (ta-wa-hay-lee) discovery was reported in the December issue of Science. Also, another specimen of Vancleavea, new, very well preserved, articulated skeleton was discovered at Ghost Ranch. The paleontological dig at Ghost Ranch is known world-wide.
It is not hard to imagine the dinosaurs walking along the edges of the buttes overlooking Ghost Ranch. From the corner of your eye it sometimes feels like you’ve caught a glimpse of the shadow of the long neck and tail of these creatures. Especially after visiting the museum, it’s more tempting to stop and study the rocks along the edges of the trails. A visit to the Ruth Hall Museum of Paleontology brings it all alive.
