Allotheria is an exinct subclass or superorder of mammals. It is a relative of the prototheria and theria.
The allotheres was a branch of successful Mesozoic mammals. The most important characteristic was the presence of lower molariform teeth equipped with two longitudinal rows of cusps.
Allotheres also had a narrow pelvis, indicating that they gave birth to tiny helpless young like marsupials do.
