Overview

• Theropods and ornithischians adapted to colder climates, showing signs of endothermy.
• Sauropods remained in warmer regions, likely due to their cold-blooded nature.
• The Jenkyns event, a period of intense volcanic activity, may have triggered this evolutionary change.
• The study analyzed fossils and climate data from over 1,000 dinosaur species.
• Birds' temperature regulation abilities may have originated from these early dinosaurs.
