Pedeticosaurus
''Pedeticosaurus'' is an extinct genus of crocodylomorph from the Clarens Formation (Early Jurassic) of South Africa. The type species ''Pedeticosaurus leviseuri'' was named by Egbert Cornelis Nicolaas van Hoepen in 1915 on the basis of a mold of a mostly complete skeleton found in a quarry near Rosendal, Free State. The mold preserves most of the right half of the skeleton including the skull, ribs, dorsal vertebrae, forelimbs and hindlimbs, but not the tail. It is currently housed in the National Museum in Bloemfontein and cataloged as QS 606. Van Hoepen originally established a new family for ''Pedeticosaurus'' called Pedeticosauridae, which he thought was closely related to the family Ornithosuchidae.〔(The Paleobiology Database )〕 In later years ''Pedeticosaurus'' was interpreted as either a member of Sphenosuchia or Protosuchia, both of which are groups of small-bodied Jurassic crocodylomorphs.〔 Paleontologist A. D. Walker erected a new group called Pedeticosauria in 1968, which he named after ''Pedeticosaurus'' and is now considered equivalent to Sphenosuchia.〔 In 1986, James M. Clark proposed that ''Pedeticosaurus leviseuri'' was a synonym of the better known protosuchian species ''Protosuchus haughtoni'' based on features such as a broad scapula bone with a concave front margin and a large squamosal bone in the skull. In 2002, Clark and Hans-Dieter Sues proposed that ''Pedeticosaurus leviseuri'' was a ''nomen dubium'' or "doubtful name" given that the features in QS 606 are too poorly preserved to distinguish ''P. leviseuri'' as its own species.〔
Paleontologists C. E. Gow and James Kitching of the Bernard Price Institute for Palaeontological Research referred a second skeleton to ''Pedeticosaurus'' in 1988. This skeleton was found just below the Clarens Formation in the slightly older Elliot Formation. It is housed in the Bernard Price Institute and cataloged as BP/1/5237. Gow and Kitching classified it as ''Pedeticosaurus sp.'' and considered it a sphenosuchian. In 2002, Clark and Sues assigned BP/1/5237 to a new genus and species of sphenosuchian named ''Litargosuchus leptorhynchus''.〔
