Pisanosaurus mertii

(Merti and Pisano's Lizard)Etymology
Pisanosaurus is derived from "Pisano" (for Argentine paleontologist Juan A. Pisano of La Plata Museum) and the Greek "sauros" (lizard).
The species epithet, mertii, honors late Araucanian naturalist Carlos Merti.
Discovery
The remains of Pisanosaurus were discovered at Agua de Las Catas (aka Hoyada del Cerro Las Lajas) in the Ischigualasto Formation, La Rioja, Argentina, by José Bonaparte, Herbst and the preparators Vince and Scaglia in 1962.
The holotype (PVL 2577) is a partial skeleton including partial upper and lower jaws, seven back vertebrae, and the lower part of a hindlimb. A shoulder blade and some forearm bones were assigned here toe but they've since been lost, and some paleontologists suspect they never belonged here in the first place.
