Catostomus columbianus was also previously placed in
Pantosteus, and appears to have undergone some hybridization with
Pantosteus in the past. However, treating it as a member of
Pantosteus makes the genus
Catostomus paraphyletic, and it thus continues to be treated as a member of
Catostomus. The following
fossil species are also known: • †
Pantosteus asitus (Smith, Stewart & Carpenter, 2013) -
Early Pliocene of Nevada, US (
White Narrows Formation) • †
Pantosteus arenatus (Miller & Smith, 1967) -
Late Pliocene of Idaho, US (
Glenns Ferry Formation) • †
Pantosteus hyomyzon (Smith, Stewart & Carpenter, 2013) -
Middle Miocene to
Late Miocene of Oregon and Washington, US (
Juntura Formation,
Drewsey Formation and
Ellensburg Formation) • †
Pantosteus oromyzon (Smith, Stewart & Carpenter, 2013) - Early Pliocene of Idaho, US (Glenns Ferry Formation) == References ==
