      A shallow shelf carbonate platform (pelletal limestone facies) stromatoporoid association from the late Sheinwoodian of Saaremaa (Baltica) contains a diverse assemblage of sclerobionts (both epi-and endobionts). The studied stromatoporoids vary from low domical to extended domical shapes. Cornulites sp. aff. C. stromatoporoides, Conchicolites sp., Anticalyptraea calyptrata, microconchids. ExceptionalIy, there are some intercalations with more than 40 per cent of clay and silt. Laminated sandstone was examined carefully, because laminae represent a perfect object for investigation of impact deformational structures. Impact structures regis-tered in the Ordovician sediment could be easily compared to artificialIy produced im-.

    Ordovician clay–carbonate part. The sandy part of the Cambrian–Ordovician sequence remains a compli cated object for stratigraphers and is poorly subdivided into individual layers that could be traced from one exposure to another.

    Hurricane Sandy produced some of the greatest destruction along the New Jersey coast in communities situated along narrow strips of land between the beach and a coastal lagoon to the west. These communities were vulnerable because they were built on low-lying terrane of _____. a) A Barrier Island b) A Wave-Cut Platform c) An Eroding Sea Cliff.   Paleodictyon is a mysterious fossil pattern found mainly in marine sediments thought to be specific of a certain paleo-depth range; it is a relatively widespread trace fossil – called this way.

Thin section micrographs of Calathium and associated biota These earliest stromatoporoids may have originated in reefs, which implies that the complex topography created by the hypercalcified sponge Calathium facilitated the emergence of stromatoporoids.

A potentially new type of non-reef sponge-bearing micritic limestone is reported from the Upper Ordovician Xiazhen Formation of south-eastern China.

The sponges are preserved as incomplete skeletons that consist of curved bifurcated and trifurcated spicules embedded in dark micrite, and can only be recognized under a petrographic microscope.

During the Late Ordovician and early Silurian, South China was located on or near the equator (Cocks and Torsvik, ; Zhan et al., ). Much of the block consisted of an open sea, dominated by.

stage level. This framework, together with some of the intensive work on the boundary levels within the system and those with the adjacent Cambrian and Silurian systems, has helped generate much new data for major research programmes such as the Great Ordovician Biodiversification Event (GOBE) and the end-Ordovician extinction events.

The stromatoporoids are presumed to be the fossils of a sponge-like animal. The fossilized stromatoporoids in the Georgetown area are found associated with Ordovician age ( – million years before present time) thinly bedded limestone of the Tanglewood Limestone Member of the Lexington Limestone.

The compact globular framework of the Duwibong stromatoporoid-bryozoan consortium represents a new type of Ordovician skeletal bioconstruction, but with a certain structural similarity to Lower Ordovician bryozoan reefs in the South China Block.
