Zanclodon

From Wikipedia, the free encyclopedia

Zanclodon ('scythe tooth' =Smilodon - preoccupied name) is the name formally used for fossil material that actually belongs to at least two genera of dinosaur from the Late Triassic. Parrish (1993), Nesbitt (2005) and Nesbitt and Norell (2006) do not believe that Zanclodon is a dinosaur and place it in the clade Suchia, incertae sedis. It was formerly placed in the Teratosauridae, within the Theropoda. It is now believed that teratosaurids were not dinosaurs, but rauisuchians.

  • Z. laevis (Plieninger 1846) [originally "Smilodon"] (type) = Plateosaurus engelhardti
  • Z. crenatus (Plieninger 1846) [originally "Smilodon"]
  • Z. bavaricus (Fraas 1894 vide Sandberger 1894) = Sauropodomorpha incertae sedis
  • Z. plieningeri (Fraas 1896) = junior synonym of Z. laevis
  • Z. arenaceus (Fraas 1896)
  • Z. cambrensis (Newton 1899) = Megalosaurus cambrensis (Galton 1998 & Storrs 1998) = "Newtonsaurus" (Welles & Pickering 1993) - nomen nudum), known from teeth in South Wales
  • Z. quenstedti (Koken 1900) = Plateosaurus engelhardti
  • Z. schutzzii (Fraas 1900) = Plateosaurus?
  • Z. subcylindrodon (Huene 1905)
  • Z. sileiacus (Jaekel 1910) = Plateosaurus
