    The Late Devonian marked the development of a suite of linear fault-bounded basins (mainly half-grabens) across the region, linked to extension on master faults that were oriented NE-SW (the Appalachian trend of Waldron et al., ), largely along the structural grain of the virtuosobs.com basin fills are typically several kilometers thick (Figs. 8–11) and may extend across terrane boundaries.

Abstract. The cephalopod facies in the East-Siberian Basin was deposited during the interval represented by the Parakidograptus acuminatus - Coronograptus cyphus graptolite Biozones of early Silurian (Rhuddanian) age.

A bathymetric study of 28 species of nautiloids from the ‘Orthoceras limestone’ facies of the Upper Silurian of SW Sardinia using the methods of Hewitt and Westermann () has indicated that the orthoconic and cyrtoconic fauna lived in a shallow environment during the late Wenlock to Ludlow and in a deeper basinal environment for the virtuosobs.com by: 1.

About a century later, Serpagli and Gnoli () revised the fossil collection of papers on Silurian and early Devonian nautiloids of. 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 (Flumini-maggiore Formation), locally rich in cephalopods, covering the rest of the Silurian. An anoxic or hypoxic event in the period between the LAD Monograptus transgrediens Zone (Transgrediens Event) in.

the latest Přídolí and the base of the Devonian Monograptus uniformis Zone (documented also from offshore sequences. from Poland) is considered to be a cause for the extinction of non-pelagic cephalopods.

Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by Nautilus and Allonautilus. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell Class: Cephalopoda, Cuvier, The Ellesmerocerids were the only shelled cephalopods that survived the end-Cambrian extinction, and all subsequent cephalopods, which diversified throughout the Ordovician period, are thus thought to be derived from these forms.

Early cephalopods had. The Devonian is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago, to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian.
