the fifth metatarsal was flattened with straight edges, instead of rounded in cross-section. In the pelvis, the ilium had a front blade that accounted for more than half of the total ilium length and extended in front of the prepubis. The ischium had a shaft that in the upper part was triangular in cross-section and in the lower part quadrangular. In the ankle the fibula touched the astragalus. Classification This dinosaur is thought to be closely related to another Patagonian ornithopod, Gasparinisaura, although the lack of skull material makes it difficult to place with precision. When originally described, Gasparinisaura and Anabisetia were thought to be basal iguanodontians, more derived than Tenontosaurus and members of the clade Euiguanodontia, and seen as endemic remnants of an early dispersion of basal iguanodontians on Pangea. Relatively recent cladistic analyses performed by Coria and others indicated that Gasparinisaura lies just outside of Iguanodontia, closer to North American ornithopods like Thescelosaurus and Parksosaurus. Anabisetia may fall in a similar position. However, in 2015, both taxa were found to be part of the clade Elasmaria along with other Antarctic and Patagonian ornithopods.
