New analysis of T. rex tooth enamel suggests the famous dinosaur was warm-blooded, according to a segment on CBC's Quirks & Quarks science programme. The finding feeds a long-running debate over whether large theropods regulated their own body temperature like modern birds and mammals rather than relying on their surroundings. Science enthusiasts online are sharing the story widely, calling it a striking shift in how these dinosaurs are understood.
Why now: Fresh research suggesting T. rex was warm-blooded challenges long-held views of dinosaur physiology.
