Congosaurus is an extinct genus of dyrosaurid mesoeucrocodylian, a family of crocodile-like prehistoric reptiles. 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^[1]^[2]. The genus was later regarded to be synonymous with Hyposaurus in 1976 and 1980^[3]^[4]. It has since been proven to be a distinct genus of dyrosaurid separate from both Dyrosaurus and Hyposaurus^[5].

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^[6]. Lateromedially compressed teeth show its close relation to C. bequaerti.
