Ganzutyrannus

Ganzutyrannus or G-Rex is a genus of large unique Tyrannosaurid living from Ganzu, China. It is an Evolved version of the Tyrannosaurus rex that was saved from extinction. it measures 60 - 70 feet long. Ganzutyrannus is the biggest known carnivore. they have devolped features like larger skulls, regrown teeth, thick bulletproof scaly skin being covered in scars and calluses. Abnormal bone growths form from old battles with prey, other predators, rivals, or even mates. Narrow, short ribcages and a large gap between the ribs. G-Rex has muscular legs that give it speed through the rough terrain of Ganzu. the G-Rex has four fingers on each hand that has evolved from two fingers. G-Rex relies on large sauropods (formerly), Gorillas, tigers, large crocodiles, and Tigradons (Tiger dogs). G-Rex can tackle large predators and was an apex predator killing T-Rex and Giganototsaurus. G-Rex also resort to cannibalism. the scales on G-Rex give the dinosaur warmth in the sluggish weather. due to their size they can pretty much use their paramount strength. their build gave them duribility in the rough terrain and in fights. G-Rex males had crests above their eyes like a tyrannosaur. during colder seasons on Ganzu island Juvenile G-Rexes actually gew a full coat of feathers. in adult years G-Rex loses its ability to grow feathers. fully grown G-Rexes use their color changing ability to regulate heat.
G-Rex has a very powerful jaw. they have a bite force of 4 tons. with the powerful bite it was easy for G-Rex to kill its prey. G-Rex is also a great swimmer. G-Rex are mostly killed by the giant gorillas in Ganzu. a G-Rex was found in Ganzu dead with a broken jaw that was probably cause by it being pried open by a giant gorilla. G-Rex kill the giant gorillas 95% of the time. but sometimes the table turns. due to a lack of G-Rexes on the Island most are inbred causing rougher looks. Also due to the radioactivity the island is exposed to due to the island formerly being used for nuclear experiments.
Diet
Ganzutyrannus eats many animals on Ganzu island. G-Rex also eats the other dinosaurs on Ganzu island such as the smaller Abelisaurid Yunanosaurus and Rugovenator. Yunanosaurus is very small compaired to G-Rex. It is 12 metre smaller than G-Rex in length. G-Rex reaching 20.9 metres in length can take down the sauropods of the island Acrodocus and Blanchiosaurus. G-Rex uses its massive size to knock the Dinosaur over before crushing it with 4 tons of pressure from its jaws. G-Rex uses its camouflaging ability to hide in the trees and water. it kills the 30 foot long crocodiles Ventasuchus and Ganzasuchus and even smaller crocs such as goniopholis. G-Rex eats Tigradon, a sabertoothed tiger dog.
Body
Unlike its ancestor Tyrannosaurus Rex. G-Rex has an Oval shaped skull with a mouth full of thick fully exposed, peg shaped, asymmetrical teeth that are located on the outside of its mouth on its lower jaw. Ganzutyrannus have four fingers on each hand that are able to slash its prey like spinosaurus, and has a waist. G-Rex has fully scaled skin with crocodilian scutes spanning its neck, back and hips. its coloration is a greenish greyish color. it has a yellowish underbelly with red eyes. due to radioactivity the G-Rex had to evolve rougher skin to stop itself from burning. 
Ecology
G-Rex is the result of Tyrannosaurus rex evolving isolated on Ganzu island over millions of years. Females lay eggs in hidden areas of Ganzu Island away from Abelisaurids and Yangraptors. when hatched baby G-Rexes form herds and hunt small abelisaurids, Huangyityrannus and Yangraptors. Huangyityrannus are a smaller version of G-Rex that were probably struck with dwarfism on the island. they kill baby G-Rexes and eat G-Rex eggs. Usually Baby G-Rexes will gang up on the Huangyityrannus and kill it. Huangyityrannus went extinct in 1843 because of the thick bulletproof skin of the G-Rexes. that would penetrate their teeth causing them to not be able to eat.
Because of the exposure to radiation on the island G-Rexes have very acidic stomach that can digesh bone and rotten meat. G-Rexes also have the ability to shoot acidic fluids at animals to burn their prey.
Extinction
In 2006 a 300 foot high tsunami wiped out the Remaining Ganzutyrannuses and sunk the island killing every other species on the island.
