What is "zephyrosaurus"

Zephyrosaurus (meaning "westward wind lizard") is a genus of orodromin ornithopod dinosaur. It is based on a partial skull and postcranial fragments discovered in the Aptian- Albian-age Lower Cretaceous Cloverly Formation of Carbon County, Montana, USA. New remains are under description, and tracks from Maryland and Virginia, also in the USA, have been attributed to animals similar to Zephyrosarus.
