Abstract

Previously undescribed Emsian vertebrates from southern Algeria (southern Ahaggar) include a new chondrichthyan Tassiliodus lessardi n. gen., n. sp. with multicuspidate teeth and scales with a distinctive histology. This is the first Emsian chondrichthyan taxon reported from the north-western margin of Gondwana. Rare acanthodian scales are assigned to Milesacanthus cf. ancestralis Burrow, Lelièvre & Janjou, 2006, an Emsian species also known from Saudi Arabia, reinforcing the Gondwanan faunal affinity.
