How much is that Asilisaurus in the window? That’s what prospective pet owners might be asking, if a newly discovered dinosaur ancestor were still alive. “It’s a lightweight, four-legged, plant-eating, scampering wonder that might have made a nice pet,” says paleontologist Paul Sereno of the University of Chicago in Illinois. The creature’s fossilized bones should cause a rethinking about dinosaur ancestors because they suggest that dinos evolved not from two-legged carnivores but from four-legged vegetarians.
