Therizinosaurs (12 marzo 130000000 anni a. C. – 12 marzo 70000000 anni a. C.)

Descrizione:

Therizinosaurs (or segnosaurs) were theropod dinosaurs belonging to the clade Therizinosauria. Therizinosaur fossils have been found in Early through Late Cretaceous deposits in Mongolia, the People's Republic of China and western North America. Various features of the forelimbs, skull and pelvis unite these finds as both theropods and as maniraptorans, close relatives to birds.
The name therizinosaur is derived from the Greek θερίζω[1] therízein, meaning 'to reap' or 'to cut off', and σαῦρος[2] saûros meaning 'lizard'. The older name segnosaur is derived from Latin segnis meaning 'slow' or 'sluggish', and Greek σαυρος, sauros, meaning 'lizard'.
