There's no denying that Tyrannosaurus rex was one of the biggest and baddest dinosaurs to ever walk the planet. But exactly how big could this ferocious dinosaur get? In a new investigation, researchers attempted to answer that question.
Paleontologists from the Canadian Museum of Nature in Ottawa, Ontario, estimated that the largest T. rex may have tipped the scales at a whopping 33,000 pounds (15,000 kilograms), making it heavier than an average school bus, which weighs about 24,000 pounds (11,000 kg).
