Muscle scars and systematic position of the Lower Palaeozoic limpets Archinacella and Barrandicella gen. n. (Mollusca)

Journal of the Czech Geological Society, volume 44 (1999), issue 1-2, 97 - 115

The new genus Barrandicella is proposed to commemorate the 200th anniversary of the birth of Joachim Barrande (1799-1883), with type species Archinacella ovata Barrande in Perner, 1903 from the Middle Ordovician (Darriwilian) of Bohemia. Barrandicella is interpreted as a gastropod (Mollusca) on the basis of a pair of well preserved muscle scars and associated tiny subsidiary scars located at the apex of the limpet shell. It lacks the dorsal band-like muscle scar characteristic of Archinacella and related genera but can be placed together with these in a revised Superfamily Archinacelloidea. No apparent link is perceived between the Archinacelloidea and the Patellogastropoda, currently widely viewed as the sister group of all other gastropods.
