Conodont biostratigraphic and taxonomic analysis of the Malpasso section were presented by Perri & Spalletta (1991, 1998). The abundant ammonoid fauna was studied by Korn & House (1997) and Korn (1998). In Spalletta & Perri (2001) the section was proposed as possible candidate for the subdivision of the Famennian. The upper part of the section was re-sampled for conodonts and geochemical analysis by Kaiser (2005). The geochemical and conodont data have been reported also in Kaiser et al. (2008, 2009). According to Perri & Spalletta (1998) and Kaiser et al. (2009) the conodont data from the Malpasso section are perfectly correlatable with the ammonoid data of Korn (1998). ). Hartenfels & Becker (2009) on the base of the identification of a typical UD V-A1 ammonoid assemblage, including Endosiphonites sp., Kosmoclymenia lamellosa (Wedekin), Nanoclymenia sp., Nodosoclymenia sp., Rectoclymenia cf. disciforme (Schindewolf), Rect. lineare (Münster), and Procymaclymenia pudica (Czarnocki), and the opportunistic bivalve of eutrophic facies Buchiola in bed ML6k, inferred the position of the Dasberg Crisis Interval between bed ML6k and ML7. The Malpasso section is one of the reference sections of the Pal Grande Formation, showing the typical features of the formation constituted mainly of grey mudstone and wackestone here particularly rich in ammonoids (Spalletta et al., 2015).
