Larval form is a conservative archetype and its study contributes to our understanding of developmental biology and theevolutionary pathways in earlier molluscs. Although early onto genetic development (embryonic and larval shell) is very important for the classification and systematics of molluscan high taxa, well preserved protoconchs are very rare in the geological record. The oldest finds of embryonic shell are known as isolated protoconchs, thus their taxonomic affinities unclear.Recently discovered, numerous, exceptionally preserved molluscan protoconchs of various affinities as well as adult shells from the Late Ordovician-early Silurian of the Boda Limestone succession in Dalama (Sweden) and the early Silurian of Sevenaya Zemlya Archipelago, Arctic Russia enable the unravelling of the taxonomic affinity and evolutionarypathway of these molluscs.
