When it come to dinosaurs, names say a lot: “tyrant lizard king” sums up the towering stature and carnivorous ways of Tyrannosaurus rex, and “arm lizard” gestures toward the Brachiosaurus‘s long front legs. And the same is true for the newest discovered dinosaur species, which has been dubbed “thunder-thighs.” That’s because scientists think its muscular thighs were so strong that it used them to boot its enemies.
The official name of this new sauropod species is Brontomerus mcintoshi. The first name is Greek for “thunder-thighs,” and the species name honors the Wesleyan University physics professor and amateur paleontologist Jack McIntosh. This dino is believed to have bigger leg muscles than any other sauropod.
A team of American and British scientists discovered the dinosaur in a quarry in Utah, and published their findings in the journal Acta Palaeontologica Polonica. Fragments from two skeletons were found: one from an adult (believed to be the mother) and a juvenile. These specimens are roughly 110 million year old, and the larger one would have weighed in at six tons and measured over 45 feet long.
