PBDB Collection

Base of Seewarte Section (Silurian of Austria)

Where: Austria (46.6° N, 12.9° E: paleocoordinates 56.2° S, 63.2° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Neocucullograptus kozlowskii graptolite zone, Cardiola Formation, Ludfordian (425.6 - 423.0 Ma)

• Higher Ludfordian

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; grainstone

• In some thin-sections the most of the clastic component are peloidal grains in sparitic matrix with subordinate larger skeletal components such as mollusc shells, bryozoans, crinoids, trilobites and brachiopod valves. Other limestone

•beds have less peloids, with bioclasts forming the major allochthonous components in predominantly sparitic rather than micritic matrix.

• Carbonates consisting of grey wacke-packstones include interbeds of few centimetre-thick layers of densely packed bioclastic grainstones. Common fossils

•were fragmented crinoids, bryozoans, brachiopods, corals and cephalopods (restricted to this interval).

Size classes: mesofossils, microfossils
