Abstract: Complementary cranial and postcranial material of the Pancheloniidae Euclastes
meridionalis (DE LA FUENTE & CASADÍO, 2000) from Danian levels of the Jagüel Formation
(late Maastrichtian-Danian) at Cerro Azul locality (Río Negro province, Argentina) is described. The
new finding of E. meridionalis represents one of the few instances in which turtles with cranial
remains similar to those previously referred to Osteopygis have well associated postcrania. This
association allows recognition of the stem-Cheloniid condition of crania and postcrania of E.
meridionalis (e. g. extremely extended secondary palate, shovel-like mandible, lateral process of the
humerus close to the caput humeri, coracoid slightly shorter than the humerus, and a dorsal process of
scapula forming relatively narrow angle with acromion).Complementary cranial and postcranial material of the Pancheloniidae Euclastes
