Discover: The top 10 Most Dangerous Dinosaurs. The T-rex, velociraptor and Spinosaurus are the best known of this list, but there are others that will surprise you for their lethality. In the event that you were a common dinosaur of the time, you might not have survived the attacks of these deadly dinosaurs. -------------------------------------------- Ramdom: -TYRANNOSAURUS REX It is the most famous dinosaur of all and its name means king lizard. He lived in the Cretaceous in what is now North America, was 39.4 feet long, 13 feet high and weighed 6 to 8 tons. Its skull was five feet long, and he had teeth that, from the outside, measured twenty-five inches, but from the root they were thirty centimeters long, making it the dinosaur with the best teeth. -SPINOSAURUS If you saw Jurassic Park 3 for sure you must remember this dinosaur. It was the largest carnivore ever known. It measured 40 feet and a half in length and weighed 20 tons. It had a long, narrow skull and small ridges over its eyes. -GIGANTOSAURUS This predator lived in what is now Argentina during the Cretaceous period. It measured 39 feet in length and weighed 8 tons. Its skull was five feet long. It was so large that it ate animals the size of a tyrannosaurus. Its front legs had three fingers with large claws. -CARCHARODONTOSAURUS This dinosaur lived in what is Africa today during the Cretaceous period. Its name means shark tooth reptile, or sharpened tooth reptile. It measured 43 feet in length and weighed 15 tons. -VELOCIRAPTOR You must have known Velociraptor thanks to Jurassic Park, but the film has some inaccuracies. In the early part of the saga, paleontologists find a velociraptor skeleton in the Montana desert, which is impossible because this animal lived in the deserts of Asia during the Cretaceous period. -UTAHRAPTOR This relative of the velociraptor was worse than the former. Its name means predator of Utah and lived in what today is that state. It was relatively small, was 23 feet long and weighed 1 102 lbs. -CARNOTAURO This dinosaur lived at the end of the Cretaceous period in what is now South America. It was 29.5 feet long and weighed more than a ton. Its appearance was terrifying because it had two horns on the top of his skull, hence his name. -PENTACERATEPS Don’t those horns look terrifying to you? This dinosaur lived in North America at the end of the Cretaceous. It was 26.2 feet long and 13.1 feet high. It weighed around of 6 tons and it looked terrifying. -ALLOSAURUS It lived in what is now the United States and Portugal at the end of the Jurassic period. It measured up to 29.5 feet of length, and 11.5 feet of height; but it did not weigh as much, only 4 850 lbs., just like an Indian rhinoceros. -ANKYLOSAURUS Its name means armored lizard. He lived in what is now North America during the Cretaceous period. It measured 5.58 feet in height, 20.5 feet in length and weighed around of six tons. It is recognized by its bony formations covered with collagen and by the enormous mallet that had in its tail. #dinosaurs #trendmax
