Calcare di Altamura (Apulia)

The Calcare di Altamura (Italian for Altamura Limestone) is a Coniacian to early Campanian geologic formation in Italy. [1] The formation comprises limestones that are highly fractured, in places karstified and dolomitized. Fossil ankylosaur tracks have been reported from the formation. [2]

Description

The Calcare di Altamura overlies the Calcare di Bari, separated by an unconformity and is overlain by the Calcare di Caranna, separated by a transgressive angular unconformity. [3] [4] The Calcare di Altamura is subdivided into the Loferitique, Stromatolique and Gorjanovicia Members. [5] The formation comprises limestones with some levels of dolomitization. The succession starts with a sequence of stromatolites and is heavily fractured and karstified. [6] The formation crops out south of the Bari–Taranto railway. The lower part of the formation is dated to the Coniacian based on the presence of the microfossils Aeolisaccus kotori , Thaumatoporella parvovesiculifera , Accordiella conica and Moncharmontia appenninica . [7] The upper part is dated to the early Campanian. [5]
