A new albulid fish, Phosphonatator oxyrhynchus, based on a single large neurocranium, is described from the deposits of the Ouled Abdoun phosphatic basin, Morocco. The matrix of the fossil contains an elasmobranch assemblage indicating a Danian age (with some redeposited Maastrichtian elements). P. oxyrhynchus is characterized notably by its elongated snout and by a reduced patch of teeth on the parasphenoid. Up to now, fossil fishes from the Ouled Abdoun phosphatic basin were mainly known by isolated remains, and the recovery of this specimen should be ranked equal to the recent discovery of important, very well-preserved new material of vertebrates in the Sidi Daoui area.
