Therizinosaurus (/ˌθɛrɪˌzɪnoʊˈsɔːrəs/; meaning "scythe lizard") is a genus of very large therizinosaurid that lived in Asia during the Late Cretaceous period in what is now the Nemegt Formation around 70 million years ago. The first remains of Therizinosaurus were found in 1948 by a Mongolian field expedition at the Gobi Desert, and later described by Evgeny Maleev in 1954 who originally thought the remains to belong to a turtle-like reptile. Therizinosaurus is known only from a few bones, including gigantic hand claws, from which it gets its name, and additional findings comprising forelimb and hindlimb elements that have been discovered during the 1960s-1980s. Therizinosaurus comprises the single species T. cheloniformis, which could grow up from 9 to 10 m (30 to 33 ft) long and weigh possibly over 3 t (3,000 kg). It had the longest known claws of any land animal, reaching above 50 cm (20 in) in length. Unlike other therizinosaurs, the claws were very stiff and elongated, but like other members, it would have been a slow-moving, long-necked/high browser herbivore equipped with a rhamphotheca (horny beak) and a wide torso for food processing. The feet ended in four weight-bearing toes, resembling the unrelated sauropodomorphs. It was one of the last and the largest representative of its unique group, the Therizinosauria. Therizinosaurus is classified as a therizinosaurid, meaning it was more derived (advanced) than the primitive therizinosauroids. At first, therizinosaurs had very complex relationships due to the lack of genera and findings at the time. Originally, they were thought to be some kind of Cretaceous sauropodomorphs or transitional ornithischians, but after years of taxonomic debate they are now placed within the Theropoda, specifically as maniraptorans. The unusually elongated hand claws of Therizinosaurus were more useful when pulling vegetation within reach rather than being used for attack or defense. Therizinosaurus was a very tall animal, likely having a reduced competition over the foliage and outmatching predators like Tarbosaurus.

Sonic in Jurassic Park is about when Reed Hammond the second grandson of John Hammond was inviting Sonic, Tails, Tempest, Knuckles, Amy Rose, Tangle, Whisper, Vector, Espio, Vector, Jewel, with Fastidious Beaver, Tom and Megan Wachowski, and Alejandro Hayek, and of course Conker the Squirrel who did survived from get eatting by the Shark and already landed on Isla Nublar from Sonic in Jaws. And also the return of the sam character from Jurassic Park, and The Lost World Jurassic Park Dr. Ian Malcolm to Isla Nublar. Since after 30 years during the incidents on Isla Nublar, Reed was now the new head of both InGen and Jurassic Park, because like his grandfather he build the park, breed dinosaurs, and entertain people, espucally Rexy the T-Rex herself was recaptured after she was escaped and roamed free on the island 30 years ago.
