Pony Prehistory: Protogryphon

Protogryphon horridus (also known as the Proto-Griffin) is the ancestor to all modern Griffins and Hippogriffs.

Found in Mongolia, the time period this Mammavian came from remains uncertain.

As you can see, it has Eagle wings, a long Lion-like tail and most of its body looks like that of a Protoceratops, which is a Sheep-sized relative of Triceratops.

The skeleton of one is seen in the Canterlot Museum in my 11th Fanfiction.net story, "The Everfree Core". [link]

NOTE: This depiction is actually based off of what some European explorers in Mongolia found, believing that the Protoceratops skull they found was a Griffin skull.
