       A possible close relative of Gasparinisaura,‭ ‬Anabisetia was a fairly small ornithopod dinosaur that roamed around what‭ ‬would become South America during the early stages of the late Cretaceous.‭ ‬Anabisetia is known mostly from the partial post cranial remains of four specimens and a single partial brain case and lower jaw.‭ ‬The lack of a more complete skull means that it is hard to establish both the head features and a more precise relationship to Gasparinisaura.
       How Anabisetia relates to other ornithopods is still uncertain,‭ ‬partly because of the uncertainty regarding Gasparinisaura at the time of writing.‭ ‬Gasparinisaura was once thought to represent a more basal iguanodont,‭ ‬but later analysis now suggests that it was closer to more advanced forms like Thescelosaurus from North America.‭ ‬If correct,‭ ‬then Anabisetia would follow Gasparinisaura by its close association.
       Possible predators of Anabisetia could have included abelisaurids,‭ ‬remains of which have been recovered from the same formation as Anabisetia.‭ ‬Possible further threats may have included carcharodontosaurids such as Mapusaurus which were alive and roaming around in other parts of Argentina during these stages of the Cretaceous.
