Allodontidae

Allodontidae is a family of extinct North American mammals that lived during the Upper Jurassic period. Allodontids were members of the order Multituberculata. They were relatively early representatives and are within the informal suborder of "Plagiaulacida". The family was named by Othniel Marsh[?] in 1889. Two genera are recognized: Ctenacodon and Psalodon.
