Triceratops sp.

An indeterminate species of Triceratops, specimen MOR 3027 (“Yoshi’s Trike”) was a large chasmosaurine horned dinosaur from the latest Cretaceous of western North America, about 68–66 million years ago. Like all Triceratops it bore two long brow horns, a nasal horn, and a broad solid neck frill, however it had particularly long brow horns, and other traits that have been interpreted as intermediate between the older T. horridus and the younger T. prorsus. This is a common issue with well-sampled evolutionary sequences - as more data points are found, the distinction between them blurs and it becomes harder to assign intermediate specimens.
