Paleontologists have discovered Khankhuuluu, a new species of tyrannosauroid dinosaur from Mongolia that represents a key transitional form in the evolution of Tyrannosaurus rex. This medium-sized predator, weighing about 750 kilograms, lived 86 million years ago and likely migrated from Asia to North America, where larger tyrannosaurs evolved. The find, detailed in a recent Nature study, highlights the dinosaur's agile hunting style and shared traits with later giants.
