Subclass Neornthes

This group of "new birds" encompasses all recent species. They began to adapt to varied environments in the Early Cretaceous, and representatives of most of the modern groups had appeared by the Early Eocene, some 50 million years ago (see pp. 170-171).

A number of extinct groups and species are known, of which the following are some of the more striking.
