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:
“They circumcised women, little girls, in Jesus’s time. Did he know? Did the subject anger or embarrass him? Did the early church erase the record? Jesus himself was circumcised; perhaps he thought only the cutting done to him was done to women, and therefore, since he survived, it was all right.”
—Alice Walker (b. 1944)
