Have ever heard of the fearsome Utahraptor? It was way scarier that the raptors in Jurassic Park, these are 14 Seriously SCARY Dinosaurs ! Mapusaurus -- Occupying what is now modern day Argentina, the largest individuals grew more than 30 feet long and weighed around three tons. It existed during the late Cretaceous period and is a close physical match for Giganotosaurus, it’s relative. Mapusaurus had bladelike teeth it used for slicing into prey, which could include one of the biggest dinosaurs that ever lived … the herbivore Argentinosaurus , which measured 115 feet long. It's speculated that these creatures may have formed in groups or packs to increase their hunting range. Deinonychus Prior to its discovery in 1964, this dinosaur had the reputation of being slow and lumbering. Instead, it turned out to be something of a speed merchant, build for rapid pursuit. Nearly twice the size of the better-known Velociraptor, it was about the same weight and is thought to have been a highly intelligent pack hunter. It could stiffen its tail to maintain its balance while pursuing prey … and had retractable five-inch claws it used to disembowel prey caught in its jaws and hands. Did you know that the Velociraptors in “Jurassic Park” were actually modelled after these guys? Maybe Deinonychus needs a better agent! Carcharodontosaurus -- That long name means “shark-toothed lizard” … a reference to the monster’s mouthful of 8 inch long serrated choppers. They could slice through flesh deep enough to leave gaping wounds that left their prey incapacitated. To make up for its smaller brain, it had powerful legs … and fossilized evidence suggests it could outrace T-rex at around 20 mph. It’s unknown if that ever happened. Its disproportionately short arms couldn’t brace its seven ton weigh if it fell. Tyrannosaurus Rex -- Of course, this is the one dinosaur that needs no introduction. And even though we’ve been focusing a bit more on terrifying beasts that may not have this level of brand awareness … we’ve still gotta put T-rex on the list. Its name means “tyrant lizard king” and weighing over 15,000 pounds, measuring over 39 feet long and topping 16 feet tall … it lived up to that name, and then some. Some other dinosaurs on the list may have been bigger, faster or smarter … but none could match the bone-splintering bite-force of T-Rex. It’s thought to be the most powerful bite-force of any land animal that ever lived. Hail to the king. Utahraptor -- We’re giving this raptor the nod over the better known velociraptor … those guys have practically become household names. But their ancestor the Utahraptor was bigger, nastier, and known for its sheer killing ability. It could reach up to 23 feet long and weighed about 1,100 pounds, comparable to the size of a polar bear. The prehistoric predator came equipped with curved claws on its hind feet measuring 12 inches long. Its powerful legs would repeatedly plunge the deadly claw into its victims, kicking and ripping its prey to death. Specimens were first discovered in Utah in 1975 … and its name means, “Utah’s Predator” Giganotosaurus (“JIG-a-note-a-SORE-uss”) -- These were among the biggest known terrestrial carnivores, and lived in modern day Argentina during the late Cretaceous period. Equal in size to, or slightly larger than Tyrannosaurus, scientists think this dinosaur could run in excess of 30 miles per hour. Thanks to an enhanced set of balance, it could likely run faster than T-Rex. But it wasn’t necessarily smarter … the brain of Giganotosaurus was half the size of T-Rex. But its keen sense of smell, 8-ton bulk and sheer athletic prowess made it a foe to be reckoned with. Likewise its serrated teeth were designed to inflict a series of fatal cuts to the body of its prey, which would eventually surrender from a combination of blood loss and exhaustion. Spinosaurus (“SPIN-oh-SORE-uss”) -- This animal lived in present day North Africa during the Cretaceous period. It’s believed to be the largest of all known carnivorous dinosaurs. At over 52 feet, that’s as long as one and a half double decker buses. And with a weight of 20 tons, it was a heavy as a herd of adult Asian elephants. Spinosaurus means “spine lizard” … a good name for this beast, which had 6.5 foot-long spines sprouting from its back that supported a huge sail of skin there. Despite that intimidating appearance, recent evidence suggests Spinosaurus spent more time in the water, and would use scavenged carrion as a supplement to its seafood diet. Its teeth were actually better suited to clamping onto slippery prey than shredding flesh from bone. Did you know Spinosaurus is thought to be the world’s first identified swimming dinosaur?
