Torvosaurus

Torvosaurus tanneri

Torvosaurus () is a genus of large megalosaurine theropod dinosaur that lived approximately 165 to 146.5 million years ago during the Callovian to Tithonian ages of the late Middle and Late Jurassic period 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 unnamed species from Germany. In 1979, the type species Torvosaurus tanneri was named. Measuring around 9 meters (30 ft) long and weighing approximately 2–2.4 metric tons (2.2–2.6 short tons), T. tanneri was among the largest terrestrial carnivores in North America during the Late Jurassic. Specimens of Torvosaurus gurneyi were measured up to 10 meters (33 ft) in length and 4–5 metric tons (4.4–5.5 short tons) in body mass, suggesting that it was much larger than T
