The Rupelo Formation is an Early Cretaceous (Berriasian) geologic formation in the Burgos Province of Castile and León in northern Spain. The formation crops out near the municipality Mambrillas de Lara in the northwesternmost part of the Cameros Basin in the Sierra de la Demanda.González Acebrón et al., 2010, p.89
Fossil sauropod tracks have been reported from the formation.Weishampel, et al., 2004, pp. 517-607 The formation was deposited under lacustrine conditions in a shallow carbonate lake, with some exposure events in the sedimentary sequence. Imprints of dinosaurs were made in carbonate mud, after they were infilled with marl. Dinosaur tracks have been assigned to sauropods, theropods and ornithopods.Rupelo Formation at Fossilworks.org An indeterminate titanosauriform sauropod humerus (MDS-VPCR, 214) similar to Duriatitan has been found in the formation, as well as a camarasaurid teeth and an indeterminate macronarian fragment of a dentary (MDS-VPCR,851).
The municipality of Mambrillas de Lara has created a dinosaur park.
