Suborder Plagiaulacida

This suborder contains the more basal multituberculates, from the mid-Jurassic to the lower Cretaceous.

Overall, these multituberculates are different from later forms because they have 3 upper incisors and four or five upper premolars; some still have canines.

It is subdivided into three informal lineages:
Family Arginbaataridae
Which suborder this family belongs to is uncertain, but it is associated with the Plagiaulacida. It is different from all other multituberculates because it has a very large fourth premolar.
