"Debate Reignites as Studies Clash Over Tiny Tyrannosaurs' True Identity"

A new study published in the journal Fossil Studies claims that certain controversial dinosaur fossils belong to Nanotyrannus lancensis, not juvenile Tyrannosaurus rex, based on growth ring analysis and anatomical reconstruction. However, the study has been met with skepticism from other experts who argue that the differences observed can be attributed to growth variation in tyrannosaurs, and that the key fossils needed to definitively settle the debate have not yet been discovered. The debate over whether Nanotyrannus is a distinct species or simply a young T. rex continues, with some paleontologists open to the possibility of a second species in the Tyrannosaurus genus but calling for more convincing evidence.
