The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs around 180 million years ago, a study suggests.
Analysing 1,000 fossils, climate models, geography and how dinosaurs evolved, the new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic era (the dinosaur era lasting from 230 to 66 million years ago).
