Check out these 10 killer dinos! - Mega Top Tens -------------------------------------------------------------------------------------------------------------------------------- These Dinosaurs Were the Ninja Assassins of the Mesozoic Era As a rule, you wouldn't want to cross paths with any of the dinosaurs that lived during the Mesozoic Era--but the fact remains that some species were much, much more dangerous than others. Here are 10 tyrannosaurs, raptors, and other kinds of dinosaurs that could turn you into lunch (or a flattened, quivering pile of bones and internal organs) faster than you can say "Jurassic Park." Deadly Dinosaur #1 - Giganotosaurus During the Cretaceous period, the dinosaurs of South America tended to be bigger and fiercer than their counterparts elsewhere on the globe. Exhibit A is Giganotosaurus, an eight- to 10-ton, three-fingered, romping, stomping predator whose remains have been found in close proximity to those of slaughtered Argentinosaurus, one of the biggest dinosaurs ever to walk the earth. The inescapable conclusion: Giganotosaurus was one of the few theropods capable of taking down a full-grown titanosaur adult (or, at least, a more manageable juvenile). Deadly Dinosaur #2 - Utahraptor Deinonychus and Velociraptor get all the press, but for sheer killing ability no raptor was more dangerous that Utahraptor, adult specimens of which weighed almost a ton (compared to 200 pounds, top, for an exceptionally big Deinonychus). With Utahraptor, the characteristic, single curved claws of the raptor family attained "Friday the 13th"-worthy sizes, kind of like the difference between a medieval broadsword and a Swiss army knife. Weirdly, this giant-sized raptor lived 50 million years before its more famous descendants, which were considerably smaller (but a lot faster). Deadly Dinosaur #3 - Tyrannosaurus Rex We'll never know if Tyrannosaurus Rex was particularly fiercer or scarier than other, less popular tyrannosaurs like Albertosaurus or Alioramus--or even whether it hunted live prey or spent most of its time feasting on already-dead carcasses. Whatever the case, there's no question that T. Rex was a fully functional killing machine when circumstances demanded, with its five- to eight-ton bulk and huge head studded with numerous, sharp teeth.
