Science in Seconds - T-Rex Won't Kill You?

Science in Seconds Know Everything RUMOURS - T-Rex Won't Kill You? Torah Kachur: Tyrannosaurus Rex is one damn scary dinosaur. Their 10 inch teeth can rip you to shreds in seconds, and their Jurassic Park screech can paralyze even the toughest prey. Then Toy Story goes and ruins it all by making them cute and helpless with ridiculously short arms. So, which is it? Tyrannosaurus Rex, the fearsome tyrant? Or T. Rex, the "Help! I can't get up!" cuddle muffin? Wait, is there even a debate? Certainly, our view of the Tyrannosaurus fossils show us just how deadly these 40-foot dinosaurs could be. Their enhanced sense of smell, the most powerful jaws in the dinosaur kingdom, and their tiny brain would make them ruthless and deadly. But there's those stupid arms! How dangerous could a predator be, if it can't get up when it falls over? Maybe, just maybe, we've been glorifying the T. Rex a little too much. There's a growing camp of paleontologists who think that the T. Rex was actually a scavenger. That enhanced sense of smell? To sniff out carrion. Those powerful jaws? To rip apart carcasses. And that tiny brain? Well, if you've ever seen a hyena, you realize they aren't exactly the sharpest knife in the drawer. Other lines of evidence have been debated and argued for over 20 years: the eye position, the shape of the tooth, and the speed have been used to argue both sides. Nasty scavenger or ruthless predator? I don't think we'll ever know the answer to this question, unless of course, we invent time travel. Or, better yet, clone the T. Rex. I know I'm in for that one.
