INV 2014.114. 15.3 14.6 12.0 6.9 Remarks – L. obtusa is closely related to L. alpina but it is markedly uniplicate and its ventral beak is strongly apsacline and slightly incurved. The relationship of L. obtusa to other species of Liospiriferina was discussed recently by VÖRÖS (2009). L. obtusa is a typical Sinemurian to Pliensbachian Alpine-Mediterranean species but it was rarely recorded also from the southern regions of NW-Europe, the Crimea and Turkey.
