"Torvosaurus", possibly the largest carnivore of its time, was a large, heavily-built, bipedal carnivore. It grew to 9 to 11 meters (30 to 36 ft) in length and an estimated weight of about 2 metric tons (2.2 tons). Its hands and arms were about average for its size. In proportion, "Allosaurus" had more powerful arms, and T. rex had tiny arms.
