Congosaurus
''Congosaurus'' is an extinct genus of dyrosaurid mesoeucrocodylian. Fossils have been found from Angola and date back to the Paleocene epoch. In 1952 and 1964 ''Congosaurus'' was proposed to be synonymous with ''Dyrosaurus''.〔Antunes, M. T. (1964). O neocretácico e o cenozóico do litoral de Angola. ''Junta de Investigações do Ultramar, Lisboa'', 254 pp.〕 The genus was later thought synonymous with ''Hyposaurus'' in 1976 and 1980.〔Buffetaut, E. (1980). Les crocodiliens Paléogènes du Tilemsi (Mali): un aperçu systématique. ''Palaeovertebrata, Mémoire jubilaire en hommage à René Lavocat'' 15–35.〕 It has since been proven a distinct genus of dyrosaurid separate from both ''Dyrosaurus'' and ''Hyposaurus''.
In 2007 a new species of ''Congosaurus'' was constructed after previously being assigned to ''Rhabdognathus'', and named ''C. compressus'', extending the geographic range of the genus into the present-day Sahara. Lateromedially compressed teeth show its close relation to ''C. bequaerti''.
