For years, scientists argued about a smaller dinosaur skeleton, wondering if it was really just a baby T. rex growing up. In 2026, researchers finally settled the debate.
In 2026, researchers finally confirmed Nanotyrannus was its own distinct species of smaller tyrannosaur dinosaur, rather than simply a juvenile T. rex still growing into its adult size, settling a debate that had divided paleontologists for years over whether the two skeletons represented the same animal at different ages.
The confirmation specifically ruled out the idea that Nanotyrannus was just a baby T. rex, and it also wasn't declared fake or not a real dinosaur — the evidence instead supported it being a genuinely separate, smaller species that lived alongside T. rex.
Telling apart a young dinosaur from a genuinely small adult species is notoriously difficult, since bones change shape a lot as an animal grows, which is exactly why this particular debate took so long for scientists to resolve.
