Eighty million years before Tyrannosaurus rex stalked the land, a creature of equal ferocity ruled the warm inland seas of ancient North America — and science has now given it a name worthy of its reign. Paleontologists have formally identified Tylosaurus rex as a distinct species of mosasaur, a marine reptile stretching over thirteen meters and standing as the undisputed apex predator of Cretaceous oceans. The discovery invites us to consider how evolution, working across separate worlds of land and sea, arrived independently at the same ruthless solution: a sovereign hunter, perfectly engine
