this trait, which had a strong effect on its position. Upon instead coding it for a modified version of the more advanced hadrosaurid condition, the connection between the two species to the exclusion of other lambeosaurines was supported. Multiple synapomorphies were found uniting to the two taxa, as well as identifying Pararhabdodon as a member of the subfamily as opposed to outside of Hadrosauridae. This relationship was again supported in Prieto-Márquez et al. (2013), where the group containing the two genera was coined as the taxonomic tribe Tsintaosaurini; a diagnosis for the tribe was provided. Their cladogram is reproduced above, on the right. In a 2020 study describing and naming Ajnabia, Nicholas Longrich and colleagues found a novel arrangement of lambeosaur phylogeny. As opposed to European lambeosaurs being spread across different lineages, all members of the subfamily from the continent — including Pararhabdodon — were found to form one monophyletic clade, which was therein named Arenysaurini. A unique combination of primitive and derived anatomical features, as well as some unique to the group, supported them forming a clade. Tsintaosaurus was not found to be close to Pararhabdodon, instead taking a more basal position.
