What is "gwawinapterus"

Gwawinapterus is a genus of Mesozoic fish known from a single fossil specimen, representing the single species Gwawinapterus beardi, from the late Cretaceous period of British Columbia, Canada. While initially described as a very late-surviving member of the pterosaur (flying reptile) group Istiodactylidae, further examination has cast doubt on the identification of the specimen as a pterosaur, and research published in 2012 identified the remains as having come from a saurodontid fish.
