Segnosaurus was a large therizinosaur that lived during the Late Cretaceous, about 102-86 million years ago. It roamed what is now southeastern Mongolia and China. During the 1970s it was one of the important finds of the Joint Soviet-Mongolian Paleontological Expeditions of a new group of dinosaurs, the segnosaurs. In 1979, the Mongolian paleontologist Altangerel Perle gave it the name Segnosaurus, meaning \"slow lizard\" from Galbin. <\/p>\n\n\n\n

It had an unusual combination of ornithischians, theropods and prosapods. The pelvis closely resembled dromaeosaurs although it was much larger. It had long, slender claw-like theropods and ankles and four toes. It had many small teeth totaling forty-eight mandibular teeth that resembled those of some theropods. It was a carnivorous dinosaur and was on two legs. <\/p>\n\n\n\n

Segnosauru was probably 6 meters long and weighed 1.3 tons.\u00a0<\/p>\n\n\n\n
