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.
Therizinosaurids were generally large and very robustly built animals that had a near convergent body plan with the more recent (and also extinct) ground sloths. The largest genera of the group are Therizinosaurus and Segnosaurus, which were about 10 m (33 ft) and 7 m (23 ft) long, respectively. The physiology of therizinosaurids include a ...
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.
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
Later research proved this theory, [256] [257] suggesting that the animal was primarily an aquatic dinosaur, whereas the film version was depicted largely as a land animal. [ 258 ] [ 259 ] The roars of the Spinosaurus were created by mixing the low guttural sounds of a lion and an alligator, a bear cub crying, and a lengthened cry of a large ...

An obituary - noting that Lasota loved "adventure, friends and family, music, blueberries, biking, computer games and animals" - even appeared in an Alaska newspaper. But the story was wrong ...
They were relatively small-sized therizinosaurs, measuring 2.2 m (7.2 ft) long and weighing about 27 kg (60 lb) in contrast to the advanced and giant Segnosaurus or Therizinosaurus. The necks of Beipiaosaurus were shorter than in most therizinosaurs, whose are characterized by elongated necks adapted for high-browsing. Also, their feet ...
