The Canadian fossil record supports anagenesis in Triceratops (Ornithischia, Ceratopsia)

Canadian Journal of Earth Sciences
Evolution of the ceratopsid dinosaur Triceratops has been hypothesized to have proceeded anagenetically, with the geologically older Triceratops horridus Marsh, 1889 having directly given rise to the younger Triceratops prorsus Marsh, 1890. This evolutionary scenario is based primarily on the upper Maastrichtian fossil record of the Hell Creek ...
