First record of a small stegosaur footprint (cf. Stegopodus) from the ?Upper Jurassic-?Lower Cretaceous red beds of the Middle Atlas, Morocco

We describe an isolated small stegosaur pes track from the ?Upper Jurassic-?Lower Cretaceous red beds of the folded Middle Atlas, Morocco. It comes from the base of the Oued El Atchane Formation which unconformably overlies the Middle Jurassic (Upper Bathonian-? Callovian) El Mers III Formation. The footprint is preserved as concave epirelief together with a natural cast on a fluvial sandstone slab and is assigned here tentatively to cf. Stegopodus isp. The new discovery confirms the presence of this ichnogenus on the African continent and highlights similarities between the Jurassic-Cretaceous dinosaur faunas of North Africa and those of Asia, North America and Western Europe.
