The world's smallest dinosaur has been recovered from the waste rock pile outside an old mine adit in northwestern Arizona. The distant cousin of the famous Tyrannosaurus-Rex ("T-Rex") would have weighed less than a pound when alive, according to discoverer, Gil Davidson, author of the scientific paper published today in the International Bulletin of Economic Taphonomy (IBET).
Davidson noted the specimen, which paleontologists have dubbed "T-Minus", is completely preserved, apparently through an unknown chemical process in the rocks.
Exploration is underway for other specimens at the site, which is next to an elementary school playground.
