Scientists used chemicals in fossilised teeth to help pin down how warm the iconic dinosaur was
2-MIN READ2-MINAssociated PressPublished: 2:53am, 17 Sep 2026Using fossilised teeth, scientists have finally taken the T. rex’s temperature – and it wasn’t too different from our own.
Researchers once thought that dinosaurs were sluggish, cold-blooded creatures. Later findings challenged that, suggesting that older dinosaurs were warm-blooded and could control their body temperature.
Most scientists agree that Tyrannosaurus rex was warm-blooded, but pinning down the exact core temperature of an extinct creature is difficult.
