Pisanosaurus was only about 3 feet (1 meter) long, and weighed perhaps around 10 to 20 pounds (4.5 to 9 kilograms). It was a herbivore (ate plants), and walked bipedally. Only one species (Pisanosaurus mertii) of Pisanosaurus is currently known, and even this is only known from a single incomplete fossilized skeleton - so many details of the creature are somewhat speculative and/or subject to debate.
Pisanosaurus was first described by Rodolfo Casamiquela in 1967. Its name means "Pisano lizard", which was chosen to honor the Argentina paleontologist, Juan A. Pisano.
Pisanosaurus lived in Argentina around the same time as the carnivorous dinosaur Herrerasaurus, and it has been suggested that Herrerasaurus may have preyed upon Pisanosaurus.
Pisanosaurus was a herbivore (plant-eater) that lived from 228 to 216 million years ago
