Megalosaurus is a dinosaur which walked the Earth about 166 million years ago, during the Jurassic Period. This dinosaur was not only one of the earliest discovered dinosaurs, it is also one of the first dinosaurs to be described in scientific literature. Megalosaurus; a name which means “great lizard.” This dinosaur was found in England in 1676 by ​​William Buckland. Then in 1827 Gideon Mantell assigned species Megalosaurus bucklandii name in honor of Mr. William Buckland. Megalosaurus has a length of about 30 feet (nine meters) and a height of 10 feet (three meters). This dinosaur weighs about a ton. Dinosaurs have great body with heavy bones and long legs with clawed feet. Dinosaur arm shorter than the feet and hands three fingers with sharp claws. It also has a small bone buttons above each eye, and large powerful jaws with sharp teeth and long, which makes it possible to eat meat. It was a fierce hunter and killer who can kill even large sauropods, which is another type of dinosaur. Scientists believe this dinosaur combed coastal regions to hunt plesiosaurs or to scavenge fish that have washed upon the shore. This scenario was put forward because many of this dinosaur’s fossil remains have been found with marine deposits. Likely, this dinosaur not only hunted Plesiosaurs or washed up fish, but probably used several hunting strategies. It was one of the smartest of the dinosaurs of the time and probably adapted its hunting style according to the prey that was available.

Intelligence is measured by its relative brain to body weight ratio. Megalosaurus was runner is relatively fast compared to other dinosaurs. Dinosaur speed are considered by scientists based on their morphology characteristics like leg length and estimated body. Speed ​​is also judged on the path way of the dinosaur fossils. Megalosaurus is a lizard-hipped dinosaur also known as saurischian
