Pietraroja Plattenkalk (Italy)

The Pietraroia Plattenkalk is a Cretaceous geologic formation located in the Italian municipality of Pietraroja, ^[1] near Benevento, in Campania region. It is of Albian age. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation ^[2] and the type locality of the formation is the La Cavere quarry, which is near the village of Pietraroja.
