Construction workers breaking ground on a road-rail terminal in Davinópolis, Maranhão, in northeastern Brazil, did not expect to make history. Nearly 26 feet underground, they hit something that hadn't seen the light of day in 120 million years: the fossilized bones of a dinosaur so large that researchers are still wrapping their heads around it.
Now known as Dasosaurus tocantinensis, the creature is shaping up to be one of the most significant dinosaur discoveries in recent memory, not just for its immense size but also for what it reveals about a world vastly different from the one we live in today.
