Saurophaganax may be a really big Allosaurus. This dinosaur would have been a huge meat-eater, possibly reaching 50 feet (15 m) long. Very little of its fossilized bones have been found so scientists are still deciding what to call this dinosaur. Some think it is a new type of Allosaurus  and some think it should have its own name. More of the fossils need to be found in order to settle the debate.
