Article: A cyamodontid placodont (Reptilia: Sauropterygia) from the Triassic of Slovenia

An isolated dentary bone from the Triassic of Toško ?elo, near Ljubljana (Slovenia) is referred to the genus Cyamodus. It is the first record of a placodont from Slovenia. The specimen is late Ladinian or early Carnian in age, and is thus among the latest known representatives of the genus Cyamodus. The late survival of Cyamodus in the southern Alpine domain, while it disappeared from the Germanic Basin in the early Ladinian, is probably linked to the persistence of fully marine conditions in the southern part of its range, after environments had become less favourable to placodonts in the Germanic Basin with the advent of the Keuper facies.
