    Microfacies analysis of samples, using thin sections, polished slabs, acetate peels, X-radiographs and scanning electron microscopy was conducted in the laboratory. These analyses confirm that depositional processes within the Kaili Formation were consistent and unshifting throughout complete thickness of the by: Silurian and Devonian assemblages are superficially similar, dominated by Lichiida and Phacopida, the latter including the well-known Calymenina. However, a number of characteristic forms do not extend far into the Devonian and almost all the remainder were wiped out by a series of extinctions in the Middle and Late Devonian.

    Microfacies characteristics as seen in thin-sections include: the types of “groundmass”, the different kinds of particle categories, depositional textures, and solution textures. All these criteria can lead to information about the sedimentological and diagenetic development of limestones. OF THE SILURIAN AND DEVONIAN ROCKS. BY HENRY NETTELROTH. PART I.

    The oldest fossils of land plants visible with the naked eye are about million years old. They are miniscule plants from the Mid-Silurian of Ireland en are called Cooksonia. Cooksonia plants had dichotomously divided little stems with small knobs at the end. These knobs were sporangia and they were filled with spores. During about 20 or 30 millions of years these were the most .

The Silurian (/ s ɪ ˈ lj ʊər. ən, s aɪ-/ sih-LYOOR-ee-ən, sy-) is a geologic period and system spanning million years from the end of the Ordovician Period, at million years ago (), to the beginning of the Devonian Period, Mya.

The Silurian is the shortest period of the Paleozoic with other geologic periods, the rock beds that define the period's start and. The Cambrian Period was followed, million years ago, by the Ordovician Period.

At that time many species died out, to be replaced by new ones in another evolutionary “explosion”, called the Great Ordovician Biodiversification Event (or GOBE).

During the Ordovician, the seas surrounding North America and Europe became rich in life, especially trilobites, brachiopods and reef. The Lower Devonian red-beds, together with the uppermost part of the underlying Tyver Group (Ivanie Fm), form a regressive succession and document. Silurian Period, in geologic time, the third period of the Paleozoic Era.

It began million years ago and ended million years ago, extending from the close of the Ordovician Period to the beginning of the Devonian Period. During the Silurian, continental elevations were generally much. The Devonian (/ d ɪ ˈ v oʊ n.

The shallow seas that covered Oklahoma during parts of the Silurian, Devonian and Carboniferous periods were home to generally similar communities. Different kinds of rhynchonelliform brachiopods and crinoids were abundant, and bivalves, cephalopods and snails were also common, Trilobites became less common over time and were reduced in variety.
