摘要：Three mammalian molars from the Early Cretaceous of Morocco reveal the existence,at that time,of two new and peculiar species,one of them assigned to the Eotheria Triconodonta (uncertain family),Dyskritodon amazighi gen. et sp. n.,the second only tentatively assigned to the Triconodonta,Ichthyoconodon jaworowskorum gen. et sp. n. The former is represented by a last lower molar which three main cusps (a,c,d) decrease regularly in size posteriorly while cusp b is very small and lingually situated,a unique condition for post-Liassic triconodonts. The second taxon (two specimens) is characterized by very narrow and trenchant teeth not intermeshing with adjacent ones,and carrying three subequal main cusps (b,a,c). Such dental morphology suggests that these mammals might have been semi-aquatic and piscivorous.
