From Wikipedia, the free encyclopedia
Neopterygii is a group of Actinopteri animals. Neopterygii means "new wings". Though there are only few changes during their evolution from the earlier actinopterygians. They appeared somewhere in the Late Permian, before the time of the dinosaurs. The Neopterygii is a very successful group of fishes, because they can move rapidly than their ancestors. Their scales and skeletons began to lighten during their evolution, and their jaws became more powerful and efficient.
