Segnosaurus ('slow lizard', from Latin segnis meaning 'slow' or 'sluggish' and Greek sauros meaning 'lizard') is a genus of theropod dinosaur belonging to the family Therizinosauridae. In Taxonomy, a type species is the species that originally defined a genus. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome.

Perle. Three specimens (consisting of a mandible, pelvis, hindlimb, scapulocoracoid, incomplete forelimb and vertebrae) were recovered from the Baynshirenstaya Svita of the Mongolian People's Republic, in sediments dated between the Cenomanian to Turonian stages (Cretaceous Period).

Segnosaurus can be distinguished from other therizinosaurs on the basis of mesial mandibular teeth that are markedly peg-like and only slightly recurved and by the moderate compression of the pedal unguals. In fields of Anatomy, anatomical terms of location are descriptive terms to help identify relative positions or directions within a species An ungual is a highly modified distal toe bone which ends in a Hoof, Claw, or nail The latero-dorsal shelf on the dentary starts at the fourteenth dentary tooth position and runs backwards for half the length of the lower jaw, unlike the shelf in Erlikosaurus, which starts at the fifth tooth position.

Cheeks ( Latin: buccae) constitute the area of the Face below the Eyes and between the Nose and the left or right Ear

In popular culture

Segnosaurus was featured in Robert Bakker's novel Raptor Red. Robert T Bakker (born March 24, 1945, in Bergen County New Jersey) is an American Paleontologist who helped reshape modern theories about Raptor Red is a 1995 fictional novel by Paleontologist Robert T In this novel, it was portrayed as a burrower. A burrow is a hole or tunnel dug into the ground by an Animal to create a space suitable for habitation temporary refuge or as a byproduct of locomotion
