Allotheria meaning "other beasts", from the Greek αλλός, allos–other and θήριον, therion–wild animal is an extinct branch of successful Mesozoic mammals The most important characteristic was the presence of lower molariform teeth equipped with two longitudinal rows of cusps Allotheria includes Multituberculata, Gondwanatheria which may be part of Multituberculata, as the sister group to Cimolodonta, and probably Haramiyida, although some studies show them to be more basal mammaliaforms rather than true mammals, therefore differing from true allotheres significantly
Allotheres also had a narrow pelvis, indicating that they gave birth to tiny helpless young like marsupials do This is a feature of all non-placental mammals
When he first identified Allotheria in 1880, Othniel Marsh regarded this group as an order within Marsupialia However, in 1997 McKenna and Bell classified Allotheria as an infraclass
