Nanotyrannus is a dinosaur of the Tyrannosauridae family that lived in North America during the Late Cretaceous Period (approximately 68-66 million years ago) and is the subject of the most heated debate as of 2025. The central debate is: 'Is Nanotyrannus an independent species, or is it a juvenile Tyrannosaurus rex?' A new study published in 2024-2025 provides strong evidence that Nanotyrannus is a separate species.
