Quaternary Period

Quaternary Period, the name applied to the Pleistocene (q.v.) by those who consider that the appearance of man is sufficient to distinguish the more modern rocks as one of the primary divisions of the stratigraphical series. Others treat it merely as a continuation of Tertiary time.

“Since the fall, God will not trust us with our own salvation, but it is both purchased and kept by Christ for us, and we for it through faith, wrought by the power of God.”
–Richard Sibbes, The Bruised Reed and Smoking Flax
