But if you placed both teams’ 53 players on a scale, their combined weight would only be a fifth of a newly discovered supermassive species of dinosaur dubbed Dreadnoughtus schrani. Weighing in at more than 65 tons and measuring 85 feet from head to toe, Dreadnoughtus is among the largest dinosaurs belonging to the gigantic family known as titanosaurs. To date, it is the most complete skeleton of a gigantic dinosaur, which allowed researchers to accurately calculate its size.
