title: NEW SPECIES OF THE LOWER CRETACEOUS GENUS MATHERONIA MUNIER-CHALMAS (BIVALVE HIPPURITIDA) IN ROMANIA
abstract: Barremian-lower Aptian requieniid rudists from the Southern Carpathians and the Apuseni Mountains, in Romania, are represented by four new species of the genus Matheronia Munier-Chalmas: Matheronia dacica, Matheronia nerae, Matheronia carinata and Matheronia silvaeregis. In the study stratigraphic interval these species possess a potential biostratigraphic value. Their evolution trough time is essentially characterized by shell size increase. Matheronia looks restricted to the North Mediterranea
