Phylogeny
Blasisaurus' discoverers performed an exact cladistic analysis to determine its phylogenetic position, which placed it as the sister taxon to Arenysaurus.[1] Together they form a tribe, the Arenysaurini, that is more derived than Tsintaosaurus and Jaxartosaurus.[1] Blasisaurus confirmed the hypothesis that, in the Late Cretaceous, different hadrosaurids from Asia and Europe migrated across land bridges.[1] Where in Lambeosaurinae Blasisaurus and Arenysaurus belong is disputed. Some put them in the tribe Lambeosaurini[2] at the base of the lambeosaurin-parasaurolophin split,[1] some in Parasaurolophini.[3] Below is the most recent cladogram including Blasisaurus and Arenysaurus, published by Penélope Cruzado-Caballero et al. in 2013:[3]
