The long-necked, lumbering Brachiosaurus that wandered the Earth150 million years ago ran a body temperature cooler than scientists had thought. The beasts most likely had special cooling mechanisms or behaviors to keep their temperatures down, a new study suggests.

These plant-eating dinosaurs, called sauropods — the largest animals ever to walk the Earth — probably had temperatures more like humans today, from around 96 degrees Fahrenheit to 100.8 F (roughly 35 to 38 degrees Celsius).
