Gwawinapterus was originally named as a new genus of pterosaur in 2011, however doubts were soon raised about the genus. Firstly a 2012 study (Witton) noted a highly unusual form of tooth replacement unknown in pterosaurs. Then another 2012 study (Vullo, Buffetaut & Everhart) came to the conclusion that the Gwawinapterus holotype fossil was not actually from a pterosaur, but of a fish.
