The Giganotosaurus was a mammoth sized carnivore which measured around 45 ft in length and weighed a little over 6 tonnes, surpassing the T. Rex by a small margin. Like most Theropods the Giganotosaurus had a prominently visible and large head and is believed to have possessed the longest skull among the various theropod dinosaurs. Thanks to its size, scientists believe the Giganotorsaurs was more than capable of going after the super sized herbivores such as the Argentinosaurus and the Titanosaurus. In fact Titanosaur fossils were found extremely close to those of the Giganotosaurus making this an even higher possibility.

Ceratosaurus was a medium sized carnivore that lived at the same time as the larger Allosaurus, in the Late Jurassic period. However, it also lived some millions of years before the emergence of the successful allosauroid. What makes it different and distinctive is the large horn on top of its nose and the two horns over its eyes. About 100 years ago, when it was first discovered, it was one of the most well-known dinosaurs. Another unusual feature is that Ceratosaurus had four fingers on its hands, instead of the more common three among the other large meat-eaters.
