National Natural Landmarks
Ghost Ranch has yielded an abundance of well-preserved Coelophysis skeletons within exposures of the Upper Triassic Chinle Formation. This reptile, one of the oldest and most primitive carnivorous dinosaurs, was known only from scanty fossil evidence until the 1947 discovery and excavation at this site. This discovery is considered by some paleontologists as one of the most important single fossil finds in the American Triassic.
Location: Rio Arriba County, NM
Year designated: 1976
