"The biggest carnivore the world has ever seen" is a title often recieved by the formidable Giganotosaurus. This colossal predator is native to Argentina during the mid-Cretaceous period. It belongs to the Carcharodontosaur family which includes genera such as Concavenator and Acrocanthosaurus.

The Giganotosaurus was one of the many species cloned by Biosyn Genetics after the Lockwood Manor incident. Biosyn's Giganotosaurus sports a dark, desaturated beige skin tone, broken up by extensive dark turquoise-hued stripes. Its body is covered in crocodile-like scutes and plating, including large keratinous spikes extending along its back. Keratin ridging is present above this carnivore’s yellowish green eyes, forming a formidable brow. No lips cover the serrated, shark-like teeth of this Carcharodontosaur. While larger than those of T. rex, the relatively small arms of Giganotosaurus have three clawed fingers.

The Giganotosaurus is the apex predator of its habitat. While fully capable of hunting prey, it is known to scavenge carcasses or even steal meals from other predators. Giganotosaurus frequently engaged in territorial conflicts with rival predators such as Tyrannosaurus, violently defending its dominion to its territory. This theropod is rather sluggish, often seen basking under the warmth of the sun’s rays. It allows for small animals to scavenge from its teeth while resting.
