Dinosaurs moved fast because of their giant, powerful butts

Dinosaurs ruled Earth for 160 million years, but they didn't get that way by running everywhere. What little we can tell about dinosaur anatomy suggests they could barely run at all. But they could power walk...thanks to their muscular rumps. » 11/13/11 12:30pm 11/13/11 12:30pm

Carnotaurus had the most ridiculously weak dinosaur arms ever

The image of the hulking T. rex and its comically undersized arms is deeply ingrained in pop culture, but it isn't really fair. They were muscular little appendages well-suited to their evolutionary purpose. The wimpy-armed Carnotaurus is another story entirely. » 9/25/11 11:30am 9/25/11 11:30am

A Batman Tyrannosaurus Rex stalks the streets of Pittsburgh

Given that all things Dark Knight Rises have momentarily taken over the Pittsburgh news cycle, it should be unsurprising that pranksters at the Art Institute of Pittsburgh (near the film's shooting) bestowed the cowl upon their campus' Tyrannosaurus Rex statue.

Tyrannosaurus Rex was a cannibal, say paleontologists

After analyzing marks and gouges on Tyrannosaurus Rex fossils, paleontologists have concluded that T. Rexes ate other T. Rexes. This cannibalism was likely the result of scavenging rather than active hunting, but researchers aren't 100% positive. » 10/16/10 7:00am 10/16/10 7:00am
