History of Conodont researches in the Carnic Alps (Austra and Italy): an overview
No full textA short history of more than sixty years of conodont researches in the Carnic Alps is outlined. It is noteworthy that the importance of these research is connected with the use of conodonts as biostratigraphic tools for relative dating of Palaeozoic to Triassic rocks, mostly limestone as the main Formations constituting the Palaeozoic sequence of the Carnic Alps. During the years of research 230 papers dealing with diff erent aspect of conodonts were produced, some of these papers are indeed dealing with CAI, taxonomy, biofacies not only on biostratigraphy. Some of the biostratigraphic papers are important at global level, as well as some of the new species originally described from the Carnic Alps. Th e holotypes of the 38 species of conodonts established from the Carnic Alps are reillustrated. The number of papers dealing with taxonomy is indicated together with the number of papers containing plates or fi gures. The papers are also subdived according to stratigraphic interval

Late and latest Famennian conodonts at the Malpasso section.
Full text linkConodont 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)
