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:

    We are living now, not in the delicious intoxication induced by the early successes of science, but in a rather grisly morning-after, when it has become apparent that what triumphant science has done hitherto is to improve the means for achieving unimproved or actually deteriorated ends.
    Aldous Huxley (1894–1963)
