***Therizinosaurus*** is an extinct genus of the therizinosaurid family that lived in Mongolia during the Late Cretaceous period around 70 million years ago.

The appearance of *Therizinosaurus* had been a debate until recent decades because of the highly incomplete nature of early finds and a lack of knowledge of the dinosaurs that would come to be categorized later as therizinosauridae. During the early phases of its discovery, it was assumed to be a species of an aquatic turtle. After several examinations and revisions, it was given the description of a gigantic carnosaur (at the time, a family that included most large carnivorous dinosaurs) measuring 55 ft in length. After the discovery of related species *Nothronychus*, the debate over its appearance ended. While its diet remains unconfirmed, *Therizinosaurus* was originally thought to be a carnivore, at the point when it was incorrectly theorized to be a much larger animal with a radically different body plan. However, today, scientists agree that *Therizinosaurus* was not carnivorous, instead being herbivorous, based on studies of its close relatives like *Erlikosaurus*, Segnosaurus, *Nothronychus*, and *Falcarius*. Based on studies of its relatives, *Therizinosaurus* is believed to have had weak jaws and probably would have fed by sitting down and using its long arms and claws to pull vegetation into its mouth. Footprints suggested to have come from unknown therizinosaurids suggest it may have had a plantigrade walking stance, similar to bears and crocodiles.

Dinosaur researchers Florence and Charlie Magovern discovered two 18-inch-long fossilized eggs in the Xixia Basin in Nanyang, China. These are perhaps the largest eggs of any animal ever found. In 1995, a study of one of these eggs conducted by the Mcgoverns and others revealed the bones of a tiny theropod, which possibly belong to a therizinosaur or a herbivore about which little is known. The fossil baby was named "Baby Louie" after photographer Louie Psihoyos.

## History

### *Jurassic World*

The DNA of *Therizinosaurus* was used in the creation of the *Indominus rex* in Template:Film. *Therizinosaurus* was eventually created after 2018 where it lived in a park with a *Giganotosaurus*.

### *Jurassic World Dominion*

A *Therizinosaurus* was cloned by Biosyn and kept within Biosyn Sanctuary. This clone was skinnier than its real counterpart, and walked with a horizontal gate rather than a more vertical one. The *Therizinosaurus* had large arms and hands, ending in three large claws and feathers covering the back of its arms and back of its body. The *Therizinosaurus* had a long neck, ending in a relatively small, boxy, and beak skull. The *Therizinosaurus* was gray, with a red back and blue above its eyes. This species is extremely territorial, and will viciously attack anything within its territory. At some point in its life, the *Therizinosaurus* within the valley was blinded and left with a white layer over its eyes similar to cataracts. As a result, the Therizinosaurus would find its way through the sanctuary via echolocation, smell, and hearing.

After ejecting from a crashing plane, Claire Dearing encounter the *Therizinosaurus* as she was hanging from the seat and parachute she ejected in. The dinosaur at first failed to notice her due to its blindness, and moving instead to fatally swat a nearby deer it heard and begin grazing. Claire used this opportunity to unbuckle and fall to the ground, but the crash alerted the *Therizinosaurus* to her presence. The *Therizinosaurus* began stalking around in search of Claire as she crawled into a pond. Claire eventually managed to get far enough in the pond to fully submerge herself until the dinosaur left.

The Therizinosaurus would be evacuated to the Biosyn compound after Lewis Dodgson tried to dispose of his bio-engineered locusts, causing a huge forest fire in the valley. During the rampage of *Giganotosaurus* and fight with the *Tyrannosaurus* known as Rexy, Kayla Watts used a flare to distract the *Giganotosaurus* away from her and the evacuating Owen Grady, Claire Dearing, Maisie Lockwood, Alan Grant, Ellie Sattler, Ian Malcolm, and Henry Wu, causing its attention to focus on the *Therizinosaurus* as it followed the flare after the *Giganotosaurus* succeeded in knocking the tyrannosaur unconscious. The *Therizinosaurus* was quick to fight back when confronted, delivering slashing wounds to the larger carcharodontosaurid, but lost a claw on its left hand to the Giganotosaurus' bites. When Rexy regained consciousness, the *Giganotosaurus* was unable to determine quickly enough which enemy was the greater threat, allowing Rexy to ram the Giganotosaurus onto the Therizinosaurus' claws, and killing Giga. finally getting a revenge, as the two dinosaurs roar in victory.

It can be assumed that the *Therizinosaurus* is out in the wild or continuing to live in the abandoned sanctuary which is now an international preserve.

The *Therizinosaurus* was 10 meters long (32.8 feet), 5 meters tall (16.4 feet), and weighed 4,935kg (5.4 tons).
