Zanclodon
''Zanclodon'' is an extinct genus of archosaurian reptile endemic to what would have been Europe during the Middle Triassic-Late Triassic epochs (245—199.6 mya).〔(PaleoBiology Database: ''Zanclodon'', basic info )〕
''Zanclodon'' ('scythe tooth') 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. The type species, ''Zanclodon laevis'', is based on a left maxilla that represents an indeterminate archosaurian. Therefore, the genus is not unambiguously identifiable.〔Hungerbühler, A. 2001. The status and phylogenetic relationships "Zanclodon" ''arenaceus'': the earliest known phytosaur?

==Taxonomy==
''Zanclodon'' was named by Plieninger (1846). It was originally named ''Smilodon'', but this name had previously been used for the saber-toothed cat (a preoccupied name), so it was renamed. It was synonymized subjectively with ''Plateosaurus'' by Marsh (1895) and Marsh (1896); it was synonymized subjectively with ''Teratosaurus'' by Romer (1956); it was considered a ''nomen dubium'' by Steel (1970); it was considered a ''nomen vanum'' by Welles (1984); it was considered a ''nomen dubium'' by Naish and Martill (2007). It was assigned to Lacertilia by Quenstedt (1867); to Megalosauridae by Lydekker (1888); to Plateosauridae by von Zittel (1911); to Zanclodontidae by Sauvage (1882), Marsh (1882), Marsh (1884), Marsh (1884), Marsh (1885), Fraas (1900), Huene (1908), Huene (1909) and Huene (1914); to Carnosauria by Huene (1923); and to Archosauria by Galton (2001).〔F.
