---|---|---|
L. Salgado et al. 2017 | Isaberrysaura differs from all other ornithischian dinosaurs in the following autapomorphies: premaxilla with posterolateral process that does not contact the lacrimal, elongated maxilla and correlated increase in the tooth count and snout length, and the posterior process of the jugal at least as long as the anterior one. The phylogenetic analysis revealed that this dinosaur also differs from all other ornithischians in the following combination of synapomorphies: two supraorbitals incorporated into the orbital margin (char. 32, from 0 to 1, shared with Agilisaurus, Haya, Thescelosaurus and Pachycephalosauria), a broad contact between the postorbital and the parietal (char. 51, from 0 to 1, shared with Pachycephalosauria), subcircular supratemporal fenestrae (char. 66, from 0 to 1, shared with most ceratopsians), and an anteriorly downturned dentary row (char. 98, from 0 to 1, shared with Thyreophora). |
