In 2012, Thompson et al. undertook an analysis of almost all known valid ankylosaurs and outgroup taxa at the time [REF].
Most recently, Arbour and Currie have presented a phylogenetic analysis of Ankylosauridae consisting of Gastonia, Cedarpelta, Chuanqilong, other basal ankylosaurids, and a number of derived ankylosaurids [REF].
