John S. Peel and Radvan J. Horný Lamaureriella vizcainoi gen. et sp. nov., from the Montagne Noire region of southern France, is a coiled, laterally compressed, bilaterally symmetrical mollusc in which prominent folds in the apertural margin produce a characteristic spiral plication across each lateral surface. Similar plications are present in technophorid rostroconchs but the prominent coiling and lack of a pegma suggest that Lamaureriella is a helcionelloid. It is the second such genus described from Early Ordovician rocks. Wiley Online Library
