Protoceratops andrewsi

(Andrew's first horn face)Etymology
Protoceratops is derived from the Greek "proto" (first), "ceras" (horn) and "ops" (face). Roy Chapman Andrews, who is honored in the species epithet, andrewsi, declared this critter the "long-sought ancestor of Triceratops" but it's no such thing. Granted, because of its frill it may appear to be closer to ceratopsids proper than, say, Psittacosaurus, but protoceratopsids (Protoceratops and family), ceratopsids (Triceratops and family) and leptoceratopsids (Leptoceratops and family) are all different branches within Neoceratopsia and non gave rise to the other.
Discovery
The first fossils of Protoceratops were discovered at Bayn Dzak ("Flaming Cliffs") in the Djadochta Formation at Ganhu, Inner Mongolia, by photographer J.B. Shackelford during a 1922 Roy Chapman Andrews-led American Central Asiatic Expeditions to the Gobi Dessert whilst looking for human ancestors. The holotype (AMNH 6251) is a well-preserved skeleton.
