Cretaceous synonyms

Probably all birds of Cretaceous age were still possessed of teeth.

Towards the end of the period, however, during the deposition of the Portlandian beds, the sea again retreated, and in the early part of the Cretaceous period was limited (in France) to the catchment basins of the Sane and Rhnein the Paris basin the contemporaneous deposits were chiefly estuarine and were confined to the northern and eastern rim.

During the later part of the Cretaceous period the sea gradually retreated and left the whole country dry.

The Cretaceous period was initiated by the subsidence of a large area to the south of the Gulf of Carpentaria, whereby a Lower Cretaceous sea spread southward, across western Queensland, western New South Wales and the north-eastern districts of South Australia.

Though Angiosperms become dominant in all known plant-bearing Upper Cretaceous deposits, their origin dates even earlier.
