Sebecosuchia
Taxonomy
Sebecosuchia was named by Colbert (1946). It is not extant. Its type is Sebecus. It was considered monophyletic by Turner and Sertich (2010) and Pol and Powell (2011) and Bronzati et al. (2012).
It was reranked as the infraorder Sebecosuchia by Walker (1970), Buffetaut (1982) and Gasparini (1984); it was reranked as the unranked clade Sebecosuchia by Turner and Calvo (2005) and Pol et al. (2012).
It was assigned to Crocodylia by Colbert (1946) and Kuhn (1966); to Crocodylia by Walker (1970); to Crocodilia by Charig (1967) and Sahni and Srivastava (1976); to Mesosuchia by Buffetaut (1982) and Gasparini (1984); to Mesoeucrocodylia by Turner and Calvo (2005); to Notosuchia by Pol and Powell (2011) and Bronzati et al. (2012); and to Ziphosuchia by Turner and Sertich (2010), Pol et al. (2012) and Pol et al. (2014).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| E. H. Colbert 1946 | Basicall ycrocodilian in cranial structure and with secondary palate.Internal nares very wide. Whole skull, and expecially the facial part, relatively much narrower and deeper than in other Crocodilia; snout very deep and with median crest above. Orbits directed laterally. Teeth reduced in number and generally strongly compressed laterally, with serrated edges, the larger teeth with crowns almost indistinguishable from those of some carnivorous dinosaurs. Vertebrae feebly amphicoelous. |
