Carcharodontosauridae is a group of carnivorous theropod dinosaurs. In 1931, Ernst Stromer named Carcharodontosauridae as a family, which, in modern paleontology, indicates a clade within Carnosauria. Carcharodontosaurids include some of the largest land predators ever known: Giganotosaurus, Mapusaurus, Carcharodontosaurus, and Tyrannotitan all rivaled Tyrannosaurus in size. Estimates give a maximum weight of 8–10 metric tons for the largest carcharodontosaurids, while the smallest carcharodontosaurids were estimated to have weighed at least 500 kilograms (1,100 lb).

Concavenator is an extinct carcharodontosaurid theropod dinosaur that lived approximately 130 million years ago during the Early Cretaceous period. The type species is C. corcovatus. Concavenator corcovatus means "Cuenca hunter with a hump". The fossil was discovered in the Las Hoyas fossil site of Spain by paleontologists José Luis Sanz, Francisco Ortega, and Fernando Escaso from the Autonomous University of Madrid and the National University of Distance Education.
