M. G. Abell. Yaverlandia was already noted in 1930 by Watson. Swinton mentioned the specimen in 1936 and also Appleby et al. noted it in 1967.

The stratigraphically oldest known pachycephalosaurid, Yaverlandia bitholus, was a small animal (length of the frontals approximately 45 mm). It is the only pachycephalosaurid that has two small domes, one on each frontal.
