Duerosuchus is an extinct genus of crocodilian. Remains have been found from Corrales del Vino in Zamora, Spain, and are middle Eocene in age (about 40 million years old). Duerosuchus is known from a single skull that is incomplete but otherwise well preserved, as well as a lower jaw, some osteoderms, and possibly some vertebrae.
Duerosuchus is a basal crocodilian thought to be closely related to brevirostrine, or short snouted crocodilians, such as alligatoroids. However, the genus has not yet been included in a phylogenetic study and its position within Crocodilia is uncertain.
