Abstract

Ankylosauria is a diverse clade of quadrupedal ornithischian dinosaurs whose remains are known from Middle Jurassic to latest Cretaceous sediments worldwide. Despite a long history of research, ankylosaur interrelationships remain poorly resolved and existing cladistic analyses suffer from limited character and taxon sampling. Here, we present the most comprehensive phylogenetic analysis of the group attempted to date. The traditional ankylosaurid–nodosaurid dichotomy is maintained. Ankylosauridae forms a well-resolved clade, which includes Zhongyuansaurus, the first ankylosaurid known to lack a tail club. Nodosauridae includes a number of taxa that were resolved either as ‘polacanthids’ or basal ankylosaurids in previous analyses. The use of a broader character sample allows analysis of the interrelationships of all valid ankylosaur species; this has revealed several previously unrecognized relationships. Stegosauria is recovered as the sister taxon to Ankylosauria, while Scelidosaurus is found to be a basal thyreophoran. Dedicated methods for coding continuous characters could be used in future to improve the resolution of ankylosaur phylogeny, particularly in order to explore the relationships within the poorly resolved nodosaurid clade.
