| Abstract: | This study presents integrated microfacies, biostratigraphic, and sedimentological analyses of five previously undocumented Upper Triassic reefal/fore-reefal to basin carbonate sections from far-travelled nappes situated today in northern Montenegro (Outer Dinarides/East Bosnian-Durmitor megaunit). The achieved data offer new insights into the evolution of shallow-water reef systems within the Dachstein Carbonate Platform during a time of pronounced global geological disturbances (intense tectonic activity, volcanism, bolide impacts, and climatic shifts). The sections studied reveal a relatively cyclic deposition of reef-derived sediments (framestone blocks and shallow-water sediments with turbiditic character) into an open marine, slope to basin environment defined by thin-shelled bivalves ("filament")-rich/siliceous packstone facies dated by conodont faunas. The analysed reef facies contain a wide range of well-preserved reef-building organisms, including microproblematica: Baccanella floriformis Pantić, Microtubus communis Flügel, Tubiphytes obscurus Maslov, Radiomura cautica Senowbari-Daryan & Schäfer, Actinotubella gusici Senowbari-Daryan, Muranella sphaerica Borza, ?Porferitubus buseri Senowbari-Daryan; calcified sponges: Cryptocoelia sp., Uvanella sp., Celyphia sp., and various corals of the Late Triassic Dachstein reef habitat. The conodont assemblages prove a latest Carnian (higher Tuvalian) to early Rhaetian age interval for the development of the studied sections. Importantly, three distinct reef-influenced depositional cycles with rapid reef progradation are identified, each disrupted by different events that directly influenced the carbonate production throughout this roughly 20 million years long time interval. These cycles challenge the notion of an undisrupted Late Triassic shallow-water carbonate factory, also highlighting the vulnerability of reef ecosystems to large-scale environmental disturbances and the difficulties to establish sequence stratigraphy cyclicity on biological controlled sedimentary systems.
