Dinosaurs may not have been cold-blooded species. Scientists previously believed animals were ectothermic when their bones exhibited growth lines, but recent studies have found growth lines in bones of mammals, specifically those that lived through long periods of unfavorable environmental conditions, like rainfall and temperature changes.
Dinosaurs may have weighed less than we previously thought. Scientists have formulated a new technique for calculating weight and size of large animals that uses lasers to measure how much skin will fit around their skeletons. This advanced method estimates that the Brachiosaur actually weighed 50,706 pounds, not 176,370 pounds like we once thought.
