Plagiaulacida is a group of extinct multituberculate mammals. Multituberculates were among the most common mammals of the Mesozoic, "the age of the dinosaurs". Plagiaulacids, an informal suborder, are the most basal of this order, and ranged from the Middle Jurassic Period to the Lower Cretaceous Period of the northern hemisphere.
Kielan-Jaworowska and Hurum (2001) divides “Plagiaulacida” into three informal lineages, the paulchoffatiids, the plagiaulicids, and the allodontids.
The Allodontid line may be a superfamily, Allodontoidea.
Both allodontids and paulchoffatiids (below) were among the most basal of the plagiaulacids. The Allodontid line contains:
The family Allodontidae is known from two genera from the Upper Jurassic Morrison Formation of North America.
The family Zofiabaataridae contains a single genus, Zofiabaatar and is also from the Morrison Formation. The affinities of a further Morrison Formation genus, Glirodon, are unclear, but it’s also within the Allodontid line.
The Paulchoffatiid line may be a superfamily, Paulchoffatioidea.
Some remains from the Middle Jurassic of England might belong within this group. Representatives are best known from the Upper Jurassic, (especially from Guimarota, Portugal), though some were still extant during the Lower Cretaceous.
