Early Cretaceous

The Early Cretaceous (geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 146 Ma to 100 Ma.

During this time many new types of dinosaurs appeared or came into prominence, including Psittacosaurus, spinosaurids and coelurosaurs, while other survivors from the Late Jurassic continued.

In the seas, the ichthyosaurs declined and eventually died out at the start of the Late Cretaceous. Angiosperms appear for the first time.

Famous quotes containing the word early:

    ...to many a mother’s heart has come the disappointment of a loss of power, a limitation of influence when early manhood takes the boy from the home, or when even before that time, in school, or where he touches the great world and begins to be bewildered with its controversies, trade and economics and politics make their imprint even while his lips are dewy with his mother’s kiss.
    J. Ellen Foster (1840–1910)
