'''''Charactosuchus''''' is an [[extinct]] [[genus]] of [[crocodilia]]n. It was assigned to the [[Family (biology)|family]] [[Crocodylidae]] in 1988.<ref>Carroll, R. L.(1988). ''[[Vertebrate Paleontology and Evolution]]''. WH Freeman and Company, New York {{ISBN|0-7167-1822-7}}</ref> Specimens have been found in [[Colombia]], [[Brazil]], [[Jamaica]], and possibly [[Florida]] and [[South Carolina]]. It was [[gharial]]-like in appearance with its long narrow snout but bore no relation to them, being more closely related to modern [[crocodile]]s than to gharials.<ref>{{cite journal | last1 = Langston | first1 = W. | year = 1965 | title = Fossil crocodilians from Colombia and the Cenozoic history of the Crocodilia in South America | journal = University of California Publications in Geological Sciences | volume = 52 | pages = 1–169 }}</ref>

=== South America ===
The [[type species]], ''C. fieldsi'', has been found from the [[Villavieja Formation]] at the [[Lagerstätte|Konzentrat-Lagerstätte]] [[La Venta (Colombia)|La Venta]] in Colombia and dates back to the [[Miocene|Middle Miocene]] ([[Laventan]]). It has also been found in the [[Mayoan]] to [[Montehermosan]] [[Urumaco Formation]] at [[Urumaco]] in [[Venezuela]],<ref name=FWCharactosuchus>[https://paleobiodb.org/classic/checkTaxonInfo?taxon_no=315620 ''Charactosuchus''] at [[Fossilworks]].org</ref> and in the [[Solimões Formation]] in [[Acre (state)|Acre State]], Brazil,<ref>{{cite journal | doi = 10.1016/j.jsames.2006.03.005 | last1 = Cozzuol | first1 = M.

In 1969, a lower jaw of a crocodilian that dated back to the [[Lutetian]] stage of the [[Eocene]] was found in the [[Chapelton Formation]] of [[Saint James Parish, Jamaica]], and was described as belonging to a new species of ''Charactosuchus'' named ''C. kugleri''.<ref>{{cite journal | last1 = Donovan | first1 = S.

Isolated teeth thought to be from the genus have been found from [[Florida]] and [[South Carolina]] and are of early [[Pliocene]] age.<ref>{{cite journal | last1 = Webb | first1 = S.D. | last2 = Tessman | first2 = N. | year = 1967 | title = Vertebrate evidence of a low sea level in the middle Pliocene | journal = Science | volume = 156 | issue =3773 | page = 379| pmid=17812382 | doi=10.1126/science.156.3773.379 | bibcode = 1967Sci...156..379W | s2cid = 22850761 }}</ref> This was thought to be evidence of the [[Great American Interchange|interchange between North and South American faunas]], with the genus first appearing in North America and then migrating down into Colombia and Brazil.<ref>Estes, R. and Báez, A.
