Giganotosaurus

At around 14 tonnes in weight and 15m in length, Giganotosaurus is one of the largest theropods ever to have lived – its name translates to ‘giant southern lizard’, in reference to its large frame and its South American habitat. It has a similar appearance to the infamous Tyrannosaurus rex, with rows of long, serrated teeth and a powerful jaw for tearing into its prey.
