Kaibabvenator swiftae is a very large, extinct ctenacanthiform fish that lived in marine environments in what is now Arizona, during the Middle Permian Period.[2] K. swiftae is known from large teeth up to 30 millimeters long found in the Kachina Microsite, of the lower Fossil Mountain Member, in the Kaibab Formation near Flagstaff, Arizona,[1] suggesting a total body length of around 5–6 metres (16–20 ft).[3] The specific name honors researcher Sandra Swift for her paleontological contributions to Northern Arizona University.[1]
