The Silurian of the Foreland Zone (southwestern Sardinia)

The Silurian exposed in southwestern Sardinia is well-known for its precious faunal content. Lower part of the sequence consists of black graptolitic shales (Genna Muxerru Formation) comprising much of the Llandovery. It is suceeded by a calcareous unit (Fluminimaggiore Formation), locally rich in cephalopods, covering the rest of the Silurian. Even the Lower Devonian is represented by limestones. A precise and detailed biostratigraphical assignment of the units has been achieved by graptolites and conodonts

Stars in the Silurian sky: Echinoderm holdfasts from the Carnic Alps, Austria

A small collection of echinoderm holdfasts from the Ludlow Cardiola Formation of the Carnic Alps (Austria) contains a wide range of morphologies as a response of environmental adaptation. In general, the holdfasts have a globous and massive dome-like profile with several processes arranged in a sub-radial disposition, so to create a sort of ‘star-like’ outline. A small central depression is common but not present on all specimens. The distinctive holdfasts are preserved in an iron-rich phase, documenting a substitution that has also affected other non-echinoderm calcareous material

The age of the La Valute limestone-Findenig limestone transition in the La Valute Section (Lower Devonian, Carnic Alps, Italy)

The Lower Devonian sequence at La Valute cave is about 8 meters thick and includes the boundary of La Volute limestone and Findenig limestone. It is represented by pelagic deposits yielding dacryoconarids, nautiloids, ostracods, trilobites, brachiopods, some crinoid stem-plates and conodonts. In order to give an age constrain for the formation-boundary fifteen conodont samples were collected and processed. Apart from some barren samples, a quite diverse Lochkovian fauna is obtained. Conodont genera like Ancyrodelloides, Belodella, Dvorakia, Flajsella, Lanea, Oulodus, Pedavis, Pseudooneotodus, Wurmiella and Zieglerodina have been identified. Distinctive conodont-assemblages belong to two middle-late Lochkovian biozones, the trigonicus Zone (upper part of La Valute limestone) and the pandora beta Zone (base of Findenig limestone), which allow the allocation of the formation-boundary near the base of the pandora beta Zone
