The earliest known ctenochasmatid remains date to the Late Jurassic Kimmeridgian age.
Previously, a fossil jaw recovered from the Middle Jurassic Stonesfield Slate formation in the United Kingdom, was considered the oldest known.
This specimen supposedly represented a member of the family Ctenochasmatidae,[4] though further examination suggested it actually belonged to a teleosaurid stem-crocodilian instead of a pterosaur.
Anders found that three subfamilies fall within the Ctenochasmatidae: Ctenochasmatinae, Gnathosaurinae and Moganopterinae, while also including several basal genera.
