Machairoceratops derives its name from the Greek term machairis, which means “curved sword,” and alludes to the forward-curved epiparietales position 1 – the cones on the back of the ruff, and the Latin word ceratops, which means “horned face.” The species name cronusi is derived from the Greek god Kronos, who is sometimes represented with a bent sword.
