 Because most of the skeleton is only known from a juvenile, and juveniles tend to express ancestral traits more strongly, a cladistic analysis would likely indicate a too basal, low, position in the evolutionary tree.For this reason, "Avaceratops" has often been excluded from such analyses.Penkalski and Dodson in 1999 concluded that "Avaceratops" most likely occupied a basal position within the Centrosaurinae but that it was also possible it was a basal member of the Ceratopsinae or just outside the clade formed by both groups.
