The dawnhorn (Plateoceros soloriens) is a denizen of southern and central Asia, protoceratopsian not much different from its Cretaceous ancestors. Dawnhorns are 3-5 meter-long, quadripedal herbivores that dwell in forests and jungles, and eat all manner of vegetation, including bamboo and small trees. Males of this species have a curious, laterally flattened nose horn, which flushes bright yellow-orange during the mating season and has earned the species its name.
The auryngo or sunhorn (P. soloriens auryngo) is a subspecies of dawnhorn that was at first mistaken for a species of its own by early specbiologists.
Auryngo lives only in Nepal while P. soloriens soloriens is a more widespread.
