The reference section of the Sardinian Ockerkalk: the Silius Section

This locality has been stratigraphically studied mostly in the last decade (Barca et al., 1994, 1995; Serpagli et al., 1998). Together with the nearby Genna Ciuerciu Section, theSilius Section is a reference section for the Sardinian Ockerkalk, and, being the mostcomplete, it is candidate as stratotype of the unit as soon as it will be formally presented.This section is the type locality of two conodont taxa: Kockelella variabilis ichnusae Serpagli & Corradini and Pseudooneotodus bicornis contiguus Corradini. Furthermore it is one of the key-sections for the Silurian Conodont Zonation proposed by Corradini & Serpagli (1998, 1999).
