The stoppani collection of large bivalves (bivalvia, megalodontida) from the upper triassic of Lombardy, Italy

Abstract

During a reorganisation of the MSNM's palaeontological collections, we uncovered specimens from the original collection of Antonio Stoppani. These included around one hundred original fragments of megalodontid bivalves (mostly internal moulds) from the Upper Triassic of Lombardy, and 14 plaster casts of original fossils, and hypothetical internal mould and valve reconstructions. Among this materials an original fragment and 8 moulds were illustrated in Stoppani, 1860-65 in his appendix on large bivalves from the Upper Triassic of Lombardy. One of the moulds is of the holotype of Conchodon infraliasicus Stoppani, 1860-65.
