'I was wrong': Dinosaur scientists agree that small tyrannosaur Nanotyrannus was real, pivotal new study finds
A groundbreaking study has resolved a long-standing debate among dinosaur scientists regarding the existence of the small tyrannosaur known as Nanotyrannus. Researchers now agree that these fossils represent a distinct species rather than juvenile Tyrannosaurus rex. This discovery is significant as it enhances our understanding of dinosaur diversity and evolution, shedding light on the ecological roles these small predators may have played during their time.
