Examples

  • But what gained greatest attention, especially from ranchers in the west, was his discovery in subsequent years of handsome skeletons of four of the progenitors of the horse: eohippus, mesohippus, miohippus and the crucial, determinative merychippus.

    Centennial

  • "Paleohippus, " of the many capacities, eohippus of the subtle form, merychippus with the horse-like appearance, pliohippus with the single hoof'these attributes persisted; there were dozens of other variations equally interesting which died out because they did not contribute to the final form.

    Centennial

  • Had not merychippus developed these self-renewing grinders, the horse as we know it could have neither developed nor survived.
