They also had better depth perception than most other dinosaurs[citation needed]. But to be fair to Steven Spielberg, only seven or eight T. rex skeletons existed in the fossil record when his classic movie was produced in 1993. Fossils tell us that dinosaurs had scaly skin, while some may have had feathers. Did T. rex have color vision? Evidence of events in a dinosaur's life make it possible for us to imagine a timeline. Some scientists have long hoped that the bones themselves would provide a map: perhaps we could count growth rings just like we do in trees. This would have included plenty of space for black-and-white and color receptors; since its ancestors (crocs) and its descendants (birds) see in color, scientists think T. rex did, too. One boy = one "smelly" appetizer. The tyrannosauroidea superfamily consists of two dozen species spanning more than 100 million years of evolution.
