Creature:Mythicopteryx atlantica

A late-surviving dromaeosaur thought to be descended from microraptor, Mythicopterex can be found on a remote island dominated by a temperate rainforest where it has had almost no interaction with or observation from humanity or other sapient races for tens of thousands of years. Recently discovered, it is believed that it may have been the origin of stories describing mythical creatures such as the gryphon and its relatives.

While the reason for its knuckle-walking stance is largely unknown, it is speculated that its microraptor ancestors may have started using their arms to walk after they significantly strengthened over time for aid in climbing.

Note that in order to view this creature correctly in-game, you need both the official Creepy & Cute pack and a mod known as CamBen's Color Pack.
