The Gigantosaurus is a little known dinosaur originating from the late Jurassic period. This dinosaur was found in England. The Gigantosaurus has a few interesting things about it. First of all it may not exist at all. This assumption is due to the fact that it was discovered and announced by a group of teenagers.
It never actually was announced by any scientist. However, if it is in fact real the Gigantosaurus is one of the largest dinosaurs to ever be discovered. Its mass would have totaled a whopping 18,000 pounds and its length 39 to 46 feet. If this dinosaur did in fact exist it would have eaten meat often in the form of the dead remains of animals.
