Abstract

The late Tortonian - early Messinian shallow marine sands of Cessaniti area (Monte Poro, Vibo Valentia, Southern Italy) yield marine and continental vertebrates. The best represented taxon is the Sirenian Metaxytherium serresii, while the terrestrial mammal assemblage includes a boselafine bovid, an hexaprotodontid hippopotamus, the giraffids Samotherium cf. boissieri and Bohlinia cf. oaten, a rhino and the elephantid Stegotetrabelodon syrticus. Until now, the latter was a species with an exclusive Afro-Arabian distribution and the record of Cessaniti is the first outside Afro-Arabia. Our attention is here focused on the occurrence of Samotherium cf. boissieri and Bohlinia cf. attica, both being species well represented in the Pikermian Biome. Although evidences of the distribution of the genus Samotherium in Late Miocene African assemblages are weak, it is reported at several sites, while a new species of Bohlinia reported in Chad is still debated. At Cessaniti, the co-occurrence of two giraffid taxa typical for the Pikermian biome together with a frankly Afro-Arabic species (S. syrticus), further marks the existence of a land connection between the Cessaniti area and North Africa as well as the evidence of a phase of expansion of the Pikermian Biome into the African continent.
