Alxasaurus is a genus of therizinosauroid theropod dinosaurs from the Early Cretaceous Bayin-Gobi Formation of Inner Mongolia.
Alxasaurus
Skeletal composite of specimens
Therizinosaurs are an extinct group of large herbivorous theropod dinosaurs whose fossils have been found across the Middle Jurassic to Late Cretaceous deposits in Europe, Asia and North America. Various features of the forelimbs, skull and pelvis unite these finds as both theropods and maniraptorans, making them relatives of birds. The name of the representative genus, Therizinosaurus, is derived from the Greek θερίζω and σαῦρος. The older representative, Segnosaurus, is derived from the Latin sēgnis ('slow') and the Greek σαῦρος.
