We describe here a bovid skull from the Upper Member of the Aït Kandoula Formation near Ouarzazate, Morocco, which can be dated by biostratigraphy to the late Miocene, Turolian-equivalent.We assign it to a new taxon, Skouraia helicoides, gen. nov., sp. nov. It has long horn-cores that are much inclined backwards, strongly spiralled in homonymous direction, very divergent, and have a strong anterolateral keel. The strong cranial flexure, broad basioccipital, and aegodont teeth demand inclusion of this new taxon within the tribe Caprini, a mostly Eurasian group with few African representatives. Skouraia must be an early offshoot of this tribe, but its highly derived cranial features suggest that the Caprini may have experienced, in the poorly known late Miocene of Africa, a broader morphological diversification than in Europe.
