The placement of Einiosaurus within Centrosaurinae is problematic due to the transitional nature of several of its skull characters, and its closest relatives are either Centrosaurus and Styracosaurus or Achelousaurus and Pachyrhinosaurus.

The latter hypothesis is supported by Horner and colleagues, where Einiosaurus is the earliest of an evolutionary series in which the nasal horns gradually change to rough bosses, as in Achelousaurus and Pachyrhinosaurus which are the second and third in this series.

The generic name Achelousaurus is a complex reference to Greek mythology.

The skull of a full-grown Achelousaurus ( including the frill horns ) is over 5 feet ( 1. 6 meters ) long.

Other members of the Centrosaurinae clade include Pachyrhinosaurus, Avaceratops, Einiosaurus, Albertaceratops, Achelousaurus, and possibly Brachyceratops, although Brachyceratops is dubious.

Achelous was also celebrated for his shapeshifting ability, just as Achelousaurus appear to combine features of other ceratopsian dinosaurs.

" Other members of the clade include Centrosaurus ( from which the group takes its name ), Pachyrhinosaurus, Avaceratops, Einiosaurus, Albertaceratops, Achelousaurus, Brachyceratops, and Monoclonius, although these last two are dubious.

In 1995 Scott D. Sampson formally described and named Einiosaurus procurvicornis from this material, as well as Achelousaurus horneri, also from a bonebed in this region.

Achelousaurus horneri are known from the U. S. state of Montana, in the Two Medicine Formation, which preserves sediments dated from the Campanian stage of the Late Cretaceous Period, between 83 and 74 million years ago.

Achelousaurus specimens are found in the highest levels of the formation, probably closer to the end of that timeframe, 74 mya.

The massive bosses on the skulls of Pachyrhinosaurus and Achelousaurus resemble those formed by the base of the horns in modern musk oxen, suggesting that they may have butted heads.

In the Two Medicine Formation, Maiasaura lived alongside the tyrannosaurid Daspletosaurus, the oviraptorosaurian Chirostenotes, the troodontid Troodon, the dromaeosaurids Bambiraptor and Saurornitholestes, the enantiornithe bird Avisaurus, the nodosaurid Edmontonia, the ankylosaurid Euoplocephalus, the ceratopsids Achelousaurus, Brachyceratops, Einiosaurus, and Styracosaurus ovatus, the hypsilophodont Orodromeus, and the hadrosaurids Hypacrosaurus stebingeri and Prosaurolophus.

Goodwin and colleagues proposed in 1992 that Styracosaurus was part of the lineage leading to Einiosaurus, Achelousaurus and Pachyrhinosaurus.

With body lengths of up to 6 meters ( 20 feet ), Achelousaurus were a medium-sized ceratopsians.

All three known skulls of Achelousaurus have rough bosses in the same places where other ceratopsians have horns, giving them the appearance of having had the horns ripped off.

Early reports suggested that Achelousaurus represented transitional forms between ceratopsians with modified horns like Einiosaurus ( with which A. horneri shares two horns on the end of the frill ), and the derived, hornless Pachyrhinosaurus ( Horner et al., 1992 ).
