Torvosaurus () is a genus of carnivorous megalosaurid theropod dinosaur that lived approximately 165 to 148 million years ago during the late Middle and Late Jurassic period (Callovian to Tithonian stages) in what is now Colorado, Portugal, Germany, and possibly England, Spain, Tanzania, and Uruguay. It contains two currently recognized species, Torvosaurus tanneri and Torvosaurus gurneyi, plus a third species from Germany that is currently unnamed. In 1979 the type species Torvosaurus tanneri was named: it is a large, heavily built, bipedal carnivore, that could grow to a length of about and weigh approximately . T. tanneri was among the largest carnivores of its time, together with Epanterias and Saurophaganax (which could both be synonyms for Allosaurus). Specimens referred to Torvosaurus gurneyi were measured up to in length and in body mass, suggesting that it was a much larger animal than T. tanneri and that it was the largest terrestrial carnivore in Europe during the late Jurassic. Based on bone morphology, Torvosaurus is thought to have had short but very powerful arms. Discovery Fossilized remains of Torvosaurus have been found in North America, Portugal, Germany, and possibly also England, Spain, Tanzania, and Uruguay. The first discovered remains referable to Torvosaurus were discovered in 1899 by Elmer Riggs in the "Freeze-out Hills" of southeastern Wyoming, northwest of the town of Medicine Bow. The material consisted of part of the left foot and right hand and they were taken to the Field Museum of Natural History in Chicago, Illinois where they were stored until being re-discovered around 2010. The specimen was assigned to Torvosaurus tanneri after being described in 2014. More remains of a large theropod that is now believed to have been Torvosaurus were discovered in the Tendaguru Formation of Tanzania and was named "Megalosaurus" ingens by Werner Janensch in 1920, based on the specimen MB R 1050, a long tooth from German East Africa (now Tanzania). It was eventually reclassified as a probable member of the Carcharodontosauridae before being reclassified as a probable member of the Torvosaurus genus in 2020; although only referred to as Torvosaurus sp., one commentator has noted it could potentially be called Torvosaurus ingens. Soto et al. described teeth of a member of the genus Torvosaurus from the Tacuarembó Formation of Uruguay. The authors noted that some of the specimens of "Megalosaurus ingens figured by Werner Janensch share the features of the Uruguayan material, and stated
