The specimen described in this paper was discovered by the University College Expedition to Lesotho in 1968. It consists of most of the right maxilla. It contains the root of a large canine followed by an edentulous area which may contain the roots of one or more premolariform teeth. Posterior to this there is evidence of five molariform teeth. The most distal of these is probably the last molar. The molariform teeth are single rooted, while their crowns, although essentially single-cusped, have some resemblance to those of small contemporaneous true mammals of the family Morganucodontidae. The affinities of this animal are discussed in the paper, and it is suggested that there was an extensive fauna of small animals in the latest Triassic and earliest Jurassic, which although reptiles, had close affinities with the early mammals.
New fossil mammal teeth are described from the Middle Jurassic (Bathonian) Forest Marble of Kirtlington, Oxfordshire, England. They are referred to a new genus and species, Eleutherodon oxfordensis, family Eleutherodontidae nov., suborder Eleutherodontida nov., order incertae sedis, assigned to Allotheria Marsh, 1880. These teeth are unique, but share with multituberculates and haramiyids the longitudinal arrangement of their cusps and with the former at least the propalinal action of the jaws in chewing, and palinal movement of the dentary during the power stroke. They differ in that respect from the Greenlandic Late Triassic Haramiyavia clemmenseni in which an orthal movement is predominant.
