Abstract:
The paper deals with newly discovered Valanginian-Hauterivian fauna of heteromorphic ammonites (Ancyloceratina) from locality south of the village of Leše above the Meža River valley (North Karavanke Mountains). Fossils were recovered from the pelagic limestone. Among the studied heteromorphic ammonites are Lower Cretacaoeus species Himantoceras trinodosum (Upper Valanginian) and Crioceratites cf. nolani (Hauterivian). Based on the accompanied ammonites (Ammonitina) from the outcrop, we biostratigraficaly confirm the presence of Lower Cretaceous ammonites fauna in the Northern Karavanke Mountains. This is also the first report on heteromorphic ammonites in Slovenia.

Abstract:
AbstractWell-preserved upper and lower jaws of the aptychus-type found inside the body chambers of two specimens of the heteromorph ammonoid Pravitoceras sigmoidale Yabe, 1902 (Nostoceratidae, Ancyloceratina) are described from the Upper Cretaceous Izumi Group in Southwest Japan. They are similar in overall morphology to those of other nostoceratid and diplomoceratid ammonoids currently known, suggesting the morphological stability of the jaw features among these taxa. The equal size of the upper and lower jaws with beak-like rostral projection suggests that the jaw apparatus of this species might function to bite and cut up prey.
