==Phylogeny== Albertochampsa is a member of the family Alligatoridae, which includes the extant (living) alligators and caimans, although it is disputed whether Albertochampsa is more closely related to the alligators or the caimans. The below cladogram from a 2018 study shows Albertochampsa as more closely related to the caimans in the subfamily Caimaninae.
