Question

Quizplus · Accepted Answer

During the Archean Eon, stable continental interiors or cratons formed. The appearance of shelly organisms in the fossil record and the dominance of dinosaurs on terrestrial life occurred much later in geologic time, during the Phanerozoic Eon. The remelting of the Earth's continental crust is not a widely accepted concept in geological science, and there is no consensus on when or if it ever occurred.
