Many other species were also named, among them Belodon buceros (named by Edward Drinker Cope in 1881),[2]Belodon kapfii (von Meyer, 1861), Belodon lepturus (Cope, 1870),[3]Belodon priscus (originally described as Compsosaurus priscus by Joseph Leidy in 1856),[4]Belodon scolopax (Cope, 1881),[2] and Belodon validus (Othniel Charles Marsh, 1893).[5] Some paleontologists of the late 19th and early 20th century believed Belodon was synonymous with Phytosaurus or Machaeroprosopus.
