Allosaurus didn't ever stop growing, but they almost stopped growing around age 20. Their fastest rate of growth was 330 lb per year, and this was their growth rate around age 15. An average Allosaurus would grow to be 28 feet long and weigh somewhere between 2,200 and 8,800 lb, depending on whose weight estimate you use.

Speed estimates are very difficult for extinct animals, especially dinosaurs because they are so different from modern animals. However, paleontologists estimate that Allosaurus's top speed was between 19 and 34 miles per hour, depending on the estimate you use.

The top speed of Allosaurus has been estimated to be somewhere between 19 and 34 miles per hour (that's 30 to 55 kilometers per hour, for more logical people who use the metric system).
