Prehistoric Giants (Other Than Dinosaurs)

Many prehistoric animals other than dinosaurs were giants. There were other giant reptiles, as well as giant species of shellfish, insects, centipedes, fish, amphibians, birds, and mammals. Now extinct, these enormous animals were forces to be reckoned with: fish as long as 90 feet, dragonflies with a wingspan of 2.5 feet, rhinoceros-like mammals 15 feet tall and weighing 16 tons, and terror birds as tall as 10 feet that could run up to 43 miles per hour.
