Abstract
New theropod tracks found in Boca do Chapim, north of Cape Espichel (Papo Seco Formation, lower Barremian) are presented. fourteen theropod tracks were identified on the lowermost bed of this formation. Two different types of theropod footprints have been identified, which occur at two different levels of this beds. The first type, consisting of smaller footprints with narrow digits, is attributed to undetermined theropod tracks; the other type, consisting of four tracks, is assigned to the ichnogenus Megalosauripus isp.. It is suggested that they were produced by medium-sized theropods, on a carbonate mud substrate, probably in a coastal environment associated with a lagoon. These tracks and others previous described in the underlying Areia do Mastro Formation, suggest a temporal continuity of the principal groups of dinosaurs that frequented this area, during the early Barremian, although the tracks of the Papo Seo Formation described in this work suggest a greater diversification of the theropod species
