?How big was Torvosaurus?

Torvosaurus tanneri was about 9 meters (30 feet) long and weighed 2 to 2.4 metric tons. Torvosaurus gurneyi was up to 10 meters (33 feet) long and weighed 4 to 5 metric tons.1 2

Scientists are not sure. No feathers have been found with Torvosaurus fossils, but some related dinosaurs may have had simple feathers. It is unknown.1

?How fast could Torvosaurus run?

Nobody knows for sure. Based on its size and leg bones, it was probably not very fast, maybe around 20 to 30 km/h (12 to 19 mph), but this is just an estimate.1
