may be just one indicator of a phylogenetic affinity with these more primitive genera that has previously been obscured, as many of the characters considered diagnostic for the genus (and indeed, for suprageneric ankylosaurian taxa) have been scored from juvenile skulls that do not exhibit all features of the adult. In particular, the exceptionally com­ plete skull of
