Therizinosaurus (/ ˌ θ ɛ r ə ˌ z ɪ n oʊ ˈ s ɔːr ə s / ⓘ; meaning 'scythe lizard') is a genus of very large therizinosaurid dinosaurs that lived in Asia during the Late Cretaceous period in what is now the Nemegt Formation around 70 million years ago. It contains a single species, Therizinosaurus cheloniformis.
Senter and James suggested the ecological niches for Therizinosaurus and Deinocheirus were characterized by high-browsing life styles. Therizinosaurus was found to be among the tallest dinosaurs in the Nemegt Formation. They also calculated that an average Therizinosaurus may have had 3 m (9.8 ft) long hindlimbs. [54] 2011
Forelimbs of Therizinosaurus, specimen IGM 100/15 displayed at Nagoya City Science Museum. Therizinosaurs were long considered an enigmatic group, whose mosaic of features resembling those of various different dinosaur groups, and scarcity of their fossils, led to controversy over their evolutionary relationships for decades after their initial discovery.
Earlier drafts for Jurassic Park III and Jurassic Park IV (later Jurassic World) had featured the aquatic reptile Kronosaurus. [43] [218] [219] [220] The Mosasaurus was suggested by Trevorrow, as part of a theme-park feeding show in which guests watch from bleachers as the animal leaps out of a lagoon and catches its prey: a shark hanging above ...
The discovery of a well-preserved fossil is helping researchers learn more about an iconic Jurassic-period species. The plesiosaur, considered a successful marine predatory ancient species, may ...
Dinosaur evolution after the Triassic followed changes in vegetation and the location of continents. In the Late Triassic and Early Jurassic, the continents were connected as the single landmass Pangaea, and there was a worldwide dinosaur fauna mostly composed of coelophysoid carnivores and early sauropodomorph herbivores.

Elite: Dangerous developer Frontier has taken the wraps off of Jurassic World Evolution, which will have you running your own park on Isla Nublar. Think of it as a very violent Rollercoaster ...
They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 million years ago; their dominance continued ...
