Notohypsilophodon
''Notohypsilophodon'' (meaning "southern ''Hypsilophodon''") is a genus of euornithopod dinosaur from the Upper Cretaceous of Argentina. It was described as the only "hypsilophodont" known from South America, although this assessment is not universally supported, and ''Gasparinisaura'' is now believed to have been a basal euornithopod as well.
==History of discovery==
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.〔
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.〔
''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.〔
