'''''Edentosuchus''''' is a [[genus]] of [[protosuchia]]n [[crocodyliform]]. It is known from [[fossil]]s found in rocks of the [[Early Cretaceous]]-age [[Tugulu Group]] from the [[Dzungaria|Junggar Basin]], [[Xinjiang]], [[People's Republic of China|China]]. Two partial skulls and several neck [[vertebra]]e are known to date. An articulated partial [[postcrania]]l skeleton may also belong to this genus, but there is no overlapping material between it and known ''Edentosuchus'' specimens.<ref name=DPetal04>{{cite journal |last=Pol |first=Diego |year=2004 |title=Basal crocodyliforms from the Lower Cretaceous Tugulu Group (Xinjiang, China), and the phylogenetic position of ''Edentosuchus'' |journal=Cretaceous Research |volume=25 |issue=4 |pages=603–622 |doi=10.1016/j.cretres.2004.05.002 |author2=Shu-an Ji |author3=James M.

== History ==
''Edentosuchus'' was described in 1973 by [[Yang Zhongjian]] (C. C. Young), and is [[holotype|based on]] [[Institute of Vertebrate Paleontology and Paleoanthropology|IVPP]] V 3236, a partial skull and associated neck vertebrae. The [[type species]] is ''E. tienshanensis''.<ref name=YZ73>{{cite journal |author=Yang Zhongjian |authorlink=Yang Zhongjian |year=1973 |title=[A new fossil crocodile from Wuerho] |journal=Memoirs of the Institute of Vertebrate Paleontology and Paleoanthropology Academia Sinica |volume=11 |pages=37–44 |language=Chinese}}</ref> A joint [[Natural History Museum of Los Angeles County]]-[[National Geological Museum of China]] expedition recovered another partial skull in 2000.<ref name=DPetal04/> Yang originally assigned it to its own family (Edentosuchidae) within Protosuchia,<ref name=YZ73/> but later research by Diego Pol and colleagues using the new material found it to be a protosuchid.<ref name=DPetal04/>

== Description ==
''Edentosuchus'' had markedly [[heterodont]] teeth. In the upper jaw, the teeth in the tip of the snout ([[premaxilla]]e) were conical. Following them, the first two teeth of the [[maxilla]]e had three [[cusp (dentistry)|cusps]]. The next two had numerous small cusps, and the fifth and last was bulbous, larger than others, and featured small cusps. In the lower jaw, several of the nine teeth on each side featured small cusps, but the second tooth was a greatly enlarged [[fang]]. The skull was only a few centimetres (or inches) long, and had a short, relatively narrow snout and wide [[anatomical terms of location|posterior]] section.<ref name=DPetal04/>

== Paleoecology ==
''Edentosuchus'' lived in a hot, seasonally arid [[floodplain]] environment. Living alongside it were turtles, [[dsungaripteridae|dsungaripterid]] [[pterosaur]]s, and [[theropoda|theropod]], [[sauropoda|sauropod]], [[stegosauria]]n, [[psittacosauridae|psittacosaurid]], and [[ornithopod]] [[dinosaur]]s.<ref name=DPetal04/>
