Urantia During the Early Land-Life Era

The Early Reptilian Age  •  The Later Reptilian Age  •  The Cretaceous Stage—The Flowering-Plant Period—The Age of Birds  •  The End of the Chalk Period

THE era of exclusive marine life has ended. Land elevation, cooling crust and cooling oceans, sea restriction and consequent deepening, together with a great increase of land in northern latitudes, all conspired greatly to change the world’s climate in all regions far removed from the equatorial zone.


The closing epochs of the preceding era were indeed the age of frogs, but these ancestors of the land vertebrates were no longer dominant, having survived in greatly reduced numbers. Very few types outlived the rigorous trials of the preceding period of biologic tribulation. Even the spore-bearing plants were nearly extinct.
