Sword-horned Spinosaurus reveals inland river hunter, upending coastal predator idea
TL;DR
Paleontologists in Niger announce a new Spinosaurus species, Spinosaurus mirabilis, featuring a 20-inch sword-like horn and a unique jaw arrangement, discovered inland far from the coast. The fossil suggests this fish-eating predator lived in forested river systems and grew to roughly the size of a Tyrannosaurus rex, with a sail-like back, challenging the view that Spinosaurus hunted exclusively in marine environments.
