The Hyperendocrin Giganotosaurus is an upcoming strain for the normal Giganotosaurus.
A large predator in its own right, the Hyperendocrin Giganotosaurus will be the second largest preadator in the Isle, being even larger than the Hyperendocrin Tyrannosaurus, but slightly smaller than the Hyperendocrin Spinosaurus, which will be the largest carnivore in the Isle. It appears to have a spiked tail. It unknown at the moment what the purposes for this spikes are, if any.
Its most definitive feature is its jaws, which have the ability to unhinge, similar to a a snakes and the Hyperendocrin Spinosaurus, although to a much larger extent. This is possibly due to it being a member of the Bleeder Branch. Its unknown if its mouth always opens like this or only when it roars and bites. It has smaller rows of teeth, which could help it bring down prey by grasping it with the bigger rows and letting the smaller ones to do the damage. However, while opening its jaws, it seems to experience pain while doing so as a result of its mutation and while it is intimidating, the Hyperendocrin Giganotosaurus suffers as a result of its jaws and even heard while doing its calls.
