'''''Laevisuchus''''' ({{IPAc-en|ˌ|l|ɛ|v|ɪ|ˈ|sj|uː|k|ə|s}}, "light crocodile") is a [[genus]] of [[Theropoda|theropod]] [[dinosaur]] from the [[Late Cretaceous]]. Its remains were discovered by [[Charles Alfred Matley]] near [[Jabalpur]] in [[Maastrichtian]] deposits in the [[Lameta Formation]] in [[India]], and were named and described by [[paleontologist]]s [[Friedrich von Huene]] and Matley in 1933.<ref>F. v. Huene and C. A. Matley, 1933, "The Cretaceous Saurischia and Ornithischia of the Central Provinces of India", ''Palaeontologica Indica (New Series), Memoirs of the Geological Survey of India'' '''21'''(1): 1-74</ref> The [[type species]] is '''''Laevisuchus indicus'''''. The generic name is derived from [[Latin]] ''laevis'', "light" and the Greek name for the Egyptian crocodile god, ''Soukhos''. The [[specific name (zoology)|specific name]] means "Indian" in [[Latin]]. It is known only from three cervical [[vertebrae]] (GSI K20/613, GSI K20/614 and GSI K27/696) and a dorsal vertebra (GSI K27/588). A [[holotype]] was not assigned by Huene and Matley and a [[lectotype]] has never been chosen from the [[syntype]]s. All remains except GSI K27/696 were lost; GSI K20/613 was rediscovered in 2012.

==Description==
''Laevisuchus'' was a small bipedal carnivore. In 1998 [[David Lambert (author)|David Lambert]] estimated it was some {{convert|2|m|ft|spell=in}} long, {{convert|0.9|m|ft|abbr=off|sp=us}} high, and approximately {{convert|30|kg|lb|abbr=on}} in weight.<ref name="lambert1998">Lambert, D. (1998). ''The Wordsworth Book of Dinosaurs'', Britain: Mackays of Chatham PLC.</ref>

==Classification==
''Laevisuchus'' was originally classified by Huene as a [[coelurid]] due to the similarity of its vertebrae with those of ''[[Aristosuchus]]''. However, an analysis in 2004 has shown it to be an [[abelisaur]]oid because of its long epipophyses, a pair of foramina on the centrum, and low and triangular neural spines. The vertebrae specifically resemble those of [[noasaurid]]s like ''[[Masiakasaurus]]'' and ''[[Noasaurus]]'' due to having more anteriorly placed neural spines and posteriorly reduced [[epipophyses]]<ref name="tykoskirowe2004">Tykoski, R.S. & Rowe, T.
