Lower Permian (Artinskian) chondrichthyan tooth remains (Petalodontidae) from Dovje (Karavanke Mts., NW Slovenia)

Fossil remains of chondrichthyan tooth bases (roots) were found in Lower Permian beds exposed along the forest road between Dovje and Plavški Rovt. These layers are part clastic development Trogkofel Group beds. They composed an alternation dark to light-grey shales, siltstone, sandstone with rare conglomerate. Within succession, or lenses dark-grey black limestones (biosparitic, biomicritic oolitic) limestone breccias occur. The consists algae, fusulinids, brachiopods, mostly crinoids (Palermocrinus Entrochus). Detail study has shown that two belong genus Petalodus, one them species Petalodus ohioensis. tongue-shaped come a rounded point distal (base end) edge. On surface base, typical oval-shaped foramina visible. In addition, osteodentine is visible on cross-section specimen. Teeth often most common fossil vertebrate reported from Carboniferous rocks USA, Europe, Russia.
