These dinosaur fossils reveal that T. rex wasn’t the only king

When it comes to gigantic predatory dinosaurs one animal reigns supreme: Tyrannosaurus rex, the tyrant lizard king, or T. rex for short. But what if T. rex never existed the way you might picture it? For almost 100 years, we've imagined T. rex as a lone king, an apex predator overseeing their world unchallenged. But that's wrong. A new T. rex fossil has since changed everything we know about this iconic carnivore and revealed something astonishing: the T. rex isn't just one species, but many. Meet Nanotyrannus.
