| - From 1985 onwards the Laboratorio de Paleovertebrados of the Universidad Nacional de la Patagonia "San Juan Bosco" organised excavations in the late Cenomanian-early Turonian-age Bajo Barreal Formation of the San Jorge Basin, northern Chubut, Patagonia. At Buen Pasto near Comodoro Rivadavia a partial juvenile skeleton lacking the skull, was found.[1] In 1998 this find was named and described by Rubén D. Martínez as the type species Notohypsilophodon comodorensis. The generic name combines a Greek νότος, notos, "south wind" with the name of the genus Hypsilophodon. The specific name refers to Comodoro Rivadavia.[1] Notohypsilophodon is based on the holotype specimen UNPSJB — PV 942, a partial skeleton including four neck, seven back, five hip, and six tail vertebrae, four rib fragments, a partial left scapula (shoulder blade), partial right coracoid, a right humerus (upper arm bone), both ulnae, and most of a left leg (minus the foot), a right fibula and astragalus, and thirteen phalanges. Because the neural arches are not fused to the bodies of the vertebrae, its describer regarded the individual as not fully grown.
