词源

carboniferous adj.

1799, "coal-bearing, containing or yielding carbon or coal," from Latin carbo (genitive carbonis) "coal" (see carbon) + -ferous "producing, containing, bearing," from ferre "to bear" (from PIE root *bher- (1) "to carry," also "to bear children").

It was used in designating the rocks which formed the great coal-beds of England, France, Germany and the United States; from 1832 with reference to the geological period when these were laid down. As a stand-alone noun (short for Carboniferous Period) by 1907.
