Kent's Cavern or Kent's Hole, limestone cave, Devonshire, SW England, near Torquay. The floor is composed of several strata, with remains indicating the prehistoric coexistence there of humans and now-extinct animals. The Rev. J. McEnery explored (1825–29) the cave and put forth the coexistence theory. The cave was extensively explored from 1865 to 1880 by William Pengelly, who found proof to support McEnery's hypothesis.
