WORD ORIGIN

early 15c., "consisting of four parts," from Latin quaternarius "of four each, containing four," from quaterni "four each, by fours," from quater "four times," related to quattuor "four" (see four). Also as a noun, "the number four" (mid-15c.), from Latin quaternarius.

In geological sense, attested from 1843 in English, proposed 1829 by French geologist Jules Pierre François Stanislas Desnoyers (1800-1887) as name for "the fourth great epoch of geological time," but because it comprises only the age of man, and the other epochs are many hundred times longer, not all accepted it.
