Play? What's that? For the young Tyrannosaurus rex, that meant fighting other dinosaurs its own age. Researchers have discovered that the prehistoric lizards fought fierce fights with one another as early as age 10 to 12. At that age, they were only half the size of a fully grown T-Rex, but perhaps twice as daring!
