zones, and to investigate the partitioning of the deformation that permitted fossil preservation through a subduction– exhumation cycle. In this contribution, I locate and describe one of the most famous outcrops of the Italian Western Alps. The “Calcschists” of this outcrop radically changed the interpretation of the Western Alps, because of their fossiliferous Fossils in high-pressure metasediments are rare, but contribute significantly to our understanding of subducted and deformed terranes. The stratigraphic age is indeed of primary importance for field geologists to derive information on the relative displacements between volumes of metamorphic rocks. Moreover, preserved fossils are ideal for studying the behavior of organic matter in subduction
