Abstract
Recently, in the Agordo area, some unquestionable fossils have been described: 1) Latest Cambrian acritarchs, within trivial black, fine grained phyllites (Col di Foglia); 2) Early Silurian graptolites, within boudins along a recrystallised shear zone cutting low-grade metapelites (Ponte Alto); 3) Middle Devonian Rugosa corals, within metalimestone boudins along the mentioned shear zone.
These fossil findings are unique in the Southalpine metamorphic basement of the Eastern Alps. Therefore, the rocks containing them deserve a careful petrographic characterization.
The aim of this contribution is to outline the specific petrographic features of these fossil-bearing rocks.
