    The paleogeographic range of the Silurian-Devonian eospiriferine brachiopod genus Myriospirifer is analysed. The genus appears in South Baltica during Early Silurian time and spread subsequently along both margins of the Rheic Ocean. During the Devonian it was widespread within Gondwana and Baltica reaching as far as Siberia. The brachiopod Stegerhynchus Foerste, occurs in Silurian strata in Canada, the U.S.A., the U.S.S.R., Gotland, and the United Kingdom. Review of the literature shows that Rhynchonella whitii praecursor Hall, is the true type species of Stegerhynchus.

Of, relating to, or being the period of geologic time from about to million years ago, the third period of the Paleozoic Era. 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 .

      Silurian- Devonian Periods 1. •Duration: about 30 millions years. • Maximunm thickness: 70, feet. • The Silurian Period (from the name of an ancient British tribe, the Silures) lies between approximately mya and mya. The Devonian period marked both the apex and the extinction of the placoderms, prehistoric fish characterized by their tough armor plating (some placoderms, such as the enormous Dunkleosteus, attained weights of three or four tons). As noted above, the Devonian also teemed with lobe-finned fish, from which the first tetrapods evolved, as well.

Acta Palaeontologica Polonica 57 (4): – In the classic section across the Silurian–Devonian boundary at Dnistrove (Podolia, Ukraine) the brachiopod fauna has never been studied in detail.

Terebratulids are one of only three living orders of articulate brachiopods, the others being the Rhynchonellida and the Thecideida.

Craniida and Lingulida include living brachiopods, but are name, Terebratula, may be derived from the Latin "terebra", meaning "hole-borer". The perceived resemblance of terebratulid shells to ancient Roman oil lamps gave the Class: Rhynchonellata.

During the Ordovician, the seas surrounding North America and Europe became rich in life, especially trilobites, brachiopods and reef. The Fox and the Bear (The Silurian #1), The Silurian, book TWO, The King of Battles, The Silurian, Book Three, Arthur's Army, The Silurian, book Four, H.
