Fossils have been found in the Early Cretaceous Itapecuru Formation in Brazil.

The genus is characterized by a particularly elongate pair of choanae in its palate.

[1] It has been named the type genus of the family Candidodontidae, first constructed in 2004.

[2] It was initially assigned to the family with a proposed sister genus, Mariliasuchus, but a recent phylogenetic analysis has shown that Mariliasuchus may instead be closer in relation to Comahuesuchus than to Candidodon and thus a member of the family Comahuesuchidae.

[3] If this is true, Candidodon would be the only member of the family Candidodontidae.
