Leyesaurus is known from the holotypePVSJ 706, a nearly complete skull with articulated mandible and some postcranialremains (vertebral columnscapular and pelvic girdles and hindlimb). The skull has a length of 18 centimeters, and Leyesaurus has been estimated to have been about 2.5 m (8.2 ft) in length. It was collected from the uppermost part of the Quebrada del Barro Formation of the Marayes-El Carrizal Basin, dating to the Lower Jurassic (based on the presence of a massospondylid like Leyesaurus within the formation). Leyesauruswas found near the locality Balde de Leyes, in the Caucete Department of San Juan Province. Within MassospondylidaeLeyesaurus was found to be most closely related to Adeopapposaurus.[1]

EtymologyEdit

Leyesaurus was first named by Cecilia Apaldetti, Ricardo N. Martinez, Oscar A. Alcober and Diego Pol in 2011 and the type species is Leyesaurus marayensis. The generic name honors the Leyes family, inhabitants of the small town Balde de Leyes, who discovered the holotype and notified the paleontologists of the San Juan Museum, and saurusGreek for "lizard". The specific namerefers to the Marayes-El Carrizal Basin, where the holotype was discovered.[1]
