 A 2009 study by Fabio Dalla Vecchia concluded that Raeticodactylus, which is known from a more complete skeleton including lower jaw, probably belong to the same genus, and possibly the same species, if the differences (such as size and the presence of a crest in the "Raeticodactylus" specimen) are not due to sex or age.Subsequent studies have supported their synonymy.Dalla Vecchia found the two forms in a sister clade of "Carniadactylus", implying that "Caviramus" was a member of the Campylognathoididae The following phylogenetic analysis follows the topology of Upchurch "et al."
