A Sauropod Tooth from the Santonian of Hungary and the European Late Cretaceous ‘Sauropod Hiatus’

Abstract The lack of sauropod body fossils from the 20 My-long mid-Cenomanian to the late Campanian interval of the Late Cretaceous in Europe is referred to as the ‘sauropod hiatus’, with only a few footprints reported from the Apulian microplate (i.e. the southern part of the European archipelago)....
