A newfound dinosaur species that used its "exceptionally powerful" thighs to kick predators likely had a bad temper to boot, one expert says.
The 46-foot-long (14-meter-long) Brontomerus mcintoshi had an immense blade on its hipbones where strong muscles would have attached, according to a new study.
"These things don't happen by accident—this is something that's clearly functional," said study co-author Mathew Wedel.
The team suspects the dinosaur—a type of sauropod, or plant-eating, four-legged lumberer—used its massive legs to either maneuver over hilly ground or deliver "good, hard" kicks to predators, said Wedel, assistant professor of anatomy at Western University of Health Sciences in Pomona, California.
Brontomerus—"thunder thighs" in Greek—may have even attacked like a modern-day chicken, relentlessly kicking and stomping pursuers to death, he added.
