These dinosaurs are recorded in several sub-basins formed during the third rifting episode related to the evolution of the Lusitanian Basin. The Kimmeridgian-Tithonian sedimentary sequence is dominated by siliciclastic deposits, indicating a continental environment. Sauropods are present all along this mainly terrestrial sequence, being recorded in the Alcobaça, Praia da Amoreira-Porto Novo, Sobral, Freixial, and the Bombarral Formations, ranging from the early Kimmeridgian to the late Tithonian. Sauropoda is the most abundant dinosaur group in the Upper Jurassic fossil record of the Lusitanian Basin and is especially well-represented in the Bombarral and Turcifal Sub-basins. Several new specimens, so far unpublished, are reported here. The sauropod fauna identified mainly includes non-neosauropod eusauropods (including turiasaurs), diplodocoids (some specimens with diplodocine affinities), basal macronarians (non-camarasaurids and camarasaurids), and titanosauriforms (some specimens with brachiosaurid affinities). Macronarians, turiasaurs and diplodocoids are generally present along the entire Kimmeridgian-Tithonian continental to transitional deposits of the Lusitanian Basin, but the known fossil record for some more exclusive groups such as camarasaurids, brachiosaurids, and diplodocines, present a more restricted stratigraphic distribution.eninfo:eu-repo/semantics/openAccess2204 Física de FluidosartículoSauropodaUpper JurassicLusitanian BasinBombarral Sub-basinArruda Sub-basinTurcifal Sub-basin
