Lower Triassic postcanine teeth with allotherian-like crowns

open access: yes, 2007
The Allotheria are fossil mammals with upper and lower post-canines usually showing two longitudinal rows of cusps separated by a central valley. The group comprises the poorly known haramiyids, mostly represented by isolated teeth, and the notably diverse and long-lived multituberculates; its monophyly is uncertain.
