趣味知識

Pisanosaurus is known from just one partial skeleton, discovered in 1962 by Galileo Juan Scaglia.1

Scientists are not sure if Pisanosaurus was a true dinosaur or a close cousin called a silesaurid.1

It lived alongside the large meat-eating dinosaur Herrerasaurus, which may have hunted it.1

The Ischigualasto Formation where it was found was a warm, humid floodplain with forests of ferns and giant conifers.1

Pisanosaurus was named after Argentine paleontologist Juan Arnaldo Pisano.1
