Gargano Promontory

The Gargano Promontory is an area of the Apulia Platform.Conti M.A., Morsilli M., Nicosia U., Sacchi E., Savino V., Wagensommer A., Di Maggio L., Gianolla P. (2005). Jurassic Dinosaur Footprints from Southern Italy: Footprints as Indicators of Constraints in Paleogeographic Interpretation. ''Palaios'' 20 (6): 534–550. The Gargano Promontory and the Maiella Mountain, which now is part of the external Apennine thrust belt, are the only areas where the transition from platform facies to basin facies is exposed on land. In the Gargano area this transition has been investigated extensively in the last decade.Luperto Sinni and Masse (1987)Masse and Luperto Sinni (1989)Bosellini and Ferioli (1988)Bosellini A., Neri C., Luciani V.
