Derived from the Latin carno [carnis] (flesh) and taurus (bull), the name Carnotaurus means meat-eating bull, alluding to its bull-like horns.he only known individual was about 8 to 9 metres (26 to 30 ft) in length, making Carnotaurus one of the largest abelisaurids. Only Ekrixinatosaurus and possibly Abelisaurus may have been similar or larger in size, though the incomplete remains of these genera make size estimations imprecise.
However,  Anatosaurus Dinosaur  has been establish to be a junior synonym of Edmontosaurus and is now an invalid name. George F. Sternberg made his most important dinosaur discovery in 1908: he was the first person to find an impression of dinosaur skin, which belonged to Anatosaurus. Sternberg made many other amazing discoveries, including the first fossil of Edmontosaurus. Some specimens, such as the well-known mount in the New York American Museum of Natural History, vary from Edmontosaurus and have been placed in the new genus Anatotitan.
