摘要: We report here new and the first mammaliamorph tracks from Early Cretaceous of Africa. The tracksite, that also bears crocodylomorph sauropod dinosaurian tracks, is in Catoca diamond mine, Lunda Sul Province, Angola. have a unique morphology, attributed to Catocapes angolanus ichnogen. et ichnosp. nov. present an anterolateral projection digit I V. with average length 2.7 cm width 3.2 are largest known unmatched size skeletal fossil record. trackways Angolaichnus adamanticus (‘ichnofamily’ Batrachopodidae) functionally pentadactyl pes, extremely outwardly rotated handprint, unusual tetradactyl plantigrade manus. One medium-sized dinosaur trackway preserved skin impressions trackmaker stride 1.6 m; second small-sized pace 75 cm.
