    Lingulate brachiopods from the lower Ordovician of the Anglo-Welsh basin. London: Palaeontographical Society, []-(OCoLC) Document Type: Book: All Authors / Contributors: M D Sutton; Michael G Bassett; Lesley Cherns. During the Middle to Upper Ordovician, portions of east-central Kentucky were part of a shallow carbonate platform that Ettensohn et al. () call the Lexington Platform (Figure 1). During this time, the rising Appalachian Mountains formed the Taconic foreland basin to the west of the mountain chain and to the east of the platform.

    A recovery brachiopod fauna occurs in the lower Niuchang Formation (upper Rhuddanian – lower Aeronian, Llandovery) of the Xinglongchang section, Meitan . A few rugose corals and possibly a crinoid or two co-existed with these brachiopods, although they were much smaller in size compared to those on the Ordovician slab. The rock is a fine-grained sandstone and may have formed slightly closer to shore than the Ordovician specimen (as .

    Lingula, one of the oldest genera of brachiopods, has survived from the earliest Ordovician to the present day. The various species look very similar, and the genus is a good example of a living fossil. Brachiopod classification is being debated by invertebrate palaeontologists. Image gallery. The oldest brachiopods can be found in rocks of early Cambrian age (about million years old). They are still alive today. Can I find them in Oklahoma? Brachiopods can be found in Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Cretaceous rocks. They are particularly common in Ordovician-Carboniferous rocks.

Brachiopods are marine invertebrates belonging to the Phylum Brachiopoda, characterized by two bilaterally symmetrical valves. During the Ordovician, brachiopods were the dominant shellfish and occurred abundantly on the seafloor globally.

In the Late Ordovician mass extinction, which probably happened in two principal phases, about 86% of species, 49%–61% of genera, and 22%–26% of families of marine animals became extinct. Brachiopods, bivalves, echinoderms, bryozoans and corals suffered severe losses. One third of all brachiopod and bryozoan families were eliminated.

Paleozoic Era, also spelled Palaeozoic, major interval of geologic time that began million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about million years ago with the end-Permian extinction, the greatest extinction event in Earth history.

The major divisions of the Paleozoic Era, from oldest to youngest, are the Cambrian ( Above Image: Rock slab of fossil brachiopods from the Upper Ordovician Waynesville Formation of Warren County, Ohio (PRI ).

Brachiopods, bryozoans and echinoderms were also heavily affected, and the cone-shaped nautiloids died out completely, except for rare Silurian forms.
