Pisanosaurus (/pIsaen@’so:r@s/), is an extinct genus and primitive dinosauriform that lived between 228 and 216 million years ago in South America’s Triassic Period. It was a ground-dwelling herbivore that was small and light-built. It could grow to approximately 1 m (3.3 feet) in length. Based on one partial skeleton found in the Ischigualasto Formation, Ischigualasto-Villa Union Basin, northwestern Argentina, only one species, Pisanosaurus Mertii, has been identified.

Pisanosaurus was first discovered by Galileo Juan Scaglia in 1962 at the Agua De Las Catas locale in the Ischigualasto Formation in La Rioja. It was based on a PVL 2577 specimen, which includes a partial skull, fragmentary right maxilla with dental, incomplete right mandibular (lower jaw), seven incomplete cervical vertebrae and seven incomplete dorsal verbrae. Molds of five sacral vertebrae were also found.

Pisanosaurus is the genus name. It means “Pisano’s lizard” and combines “Pisano”, in honor of Juan Arnaldo Pisano, an Argentine paleontologist. Rodolfo Casamiquela, an Argentine paleontologist, first described and named Pisanosaurus in 1967. Pisanosaurus Mertii is the only valid type of Pisanosaurus. Carlos Merti, an Araucanian naturalist, was the inspiration for this name.
