Norman followed their 1990 opinion on Alocodon in 2004, though they noted that further study could potentially support the validity of the taxon. Features of the teeth identified by José I. Canudo and colleagues in 2004 instead supported a more specific position for Alocodon, as a member of Ankylosauria. Canudo et al. based this assignment on the anatomy of the denticles and cingulum of the crown. A denticulate cingulum present in Alocodon was also identified as an ankylosaur feature, by Paul M. Barrett and colleagues in 2010, though more material was considered necessary to verify the importance of the feature. Alocodon was considered an ornithopod by Filippo M. Rotatori and colleagues in 2020. Because of its incomplete nature, Alocodon has been excluded from phylogenetic analyses. A diversity of fauna is known from the Praia de Pedrógão locality alongside Alocodon, including the pterosaur Rhamphorhynchus, fragments of the shell of a turtle, remains of Goniopholis and another intermediate crocodilian, material from a kuehneosaurid and another unnamed lizard, an unnamed salamander, and teeth from the teleost fishes Caturus, Lepidotes and Proscinetes, and two hybodontid sharks: Asteracanthus and an unnamed small form. Footprints and teeth of a very large theropod also indicate their presence in the locality.
