Abstract
    The caudal skeleton of Eoplethodus chaneti gen, and sp. nov., a fossil teleost from the marine Albian (Cretaceous) of France is described. This fish belongs to the cohort Clupeocephala and the order Tselfatiiformes (=Bananogmiiformes). The caudal skeleton of E. chaneti still offers a well developed preural 1 vertebra, three epurals, a pair of stegurals, and normal preural 1 hemal arch and parhypural. It is thus more primitive than the one of the Plethodidae, the family grouping all the other genera of this order, where the preural 1 vertebra is reduced, the epurals and parhypural lost, the preural 1 hemal arch atrophied or lost, and the pair of stegurals changed into a false preural 1 neural spine. E. chaneti allows a better understanding of the evolution of the caudal skeleton within the Tselfatiiformes.
