The cast of "The Standard Deviants," PBS's MTV-style education show for kids and young teens, present a fast-paced array of dinosaur facts and speculation. Fact: Allosaurus had 6-in. claws "that could crush your skull like a styrofoam cup." Speculation: dinosaurs' skin color. But the length of their reign is certain: 150 million years. Of course, they didn't all live at the same time. "There's less time between us and T. Rex," says one Deviant, "than there is between T. Rex and Stegosaurus."
