Zanclodon ("scythe tooth") is an extinct genus of archosaurian found in Middle Triassic deposits in southern Germany.[1]

Taxonomy

Zanclodon was originally named Smilodon by Plieninger (1846), but this name had previously been used for the saber-toothed cat (a preoccupied name), prompting Plieninger to erect the replacement name Zanclodon.[2] It was formerly placed in the Teratosauridae, within the Theropoda, and at times, plateosaurid material was mistakenly referred to Zanclodon (see Galton 2001). The type species, Zanclodon laevis, is based on a left maxilla that represents an indeterminate archosaurian. Therefore, the genus is not unambiguously identifiable.[3]

Species

  • Z. laevis (Plieninger 1846) [originally "Smilodon"] (type)
  • Z. crenatus (Plieninger 1846) [originally "Smilodon"]
  • Z. bavaricus (Fraas 1894 vide Sandberger 1894)=Sauropodomorpha incertae sedis[3]
  • Z. plieningeri (Fraas 1896)=junior synonym of Z. laevis[3]
  • Z. arenaceus (Fraas 1896) = a possible parasuchian[4][5]
  • Z. cambrensis (Newton 1899)='"Newtonsaurus" (Welles & Pickering 1993) – nomen nudum, known from teeth in South Wales
  • Z. schutzii (Fraas 1900)=Batrachotomus
  • Z. silesiacus (Jaekel 1910)= nomen dubium at Archosauria indeterminate[6]
