Pegomastax (Tyler Keillor)

Its name, riddled with plosives like "p," "g" and "x", is a harbinger in itself. Announced to the world in 2012, Pegomastax may have been the ugliest ornithopod that ever lived (and judging by the other genera on this list, including Hippodraco, Jeyawati and Tianyulong, that's quite a distinction). Not only was the weirdly beaked Pegomastax ("thick jaw") equipped with two prominent fangs, but its entire body was covered with bristles; mercifully, this hideous dinosaur only measured about two feet from head to tail.
