Therizinosaurus is a genus of very large therizinosaurid dinosaurs that lived in the Maastrichtian age during the Late Cretaceous period in what is now Asia roughly 69-66 million years ago. It contains a single species, Therizinosaurus cheloniformis, known from the fossiliferous Nemegt Formation. The first remains of Therizinosaurus were found in 1948 by a Mongolian field expedition in the Gobi Desert and later described by Evgeny Maleev in 1954. The genus is only known from a few bones, including gigantic manual unguals, from which it gets its name, and additional findings comprising fore and hindlimb elements that were discovered from the 1960s through the 1980s.
