This book was released on 2014-02-20 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide. The fauna includes 20 genera and 29 species, of which three genera and six species are new. Eighteen species are new to Baltica. The fauna shows strong similarities to later Silurian assemblages in Arctic Canada, but one endemic species comprises ca. 50% of the fauna. The fauna shows that lithistid sponges recovered well from the late Ordovician extinction in some areas, and became widely spread in the early Silurian. In contrast, non-lithistid sponges like, such as hexactinellids, appear to have evolved rapidly during the Late Ordovician – early Silurian interval, and some modern groups probably originated in inshore habitats.

Keith Rigby and published by Geological Survey of Canada. This book was released on 1989 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes one of the most diverse Silurian sponge faunas known in North America. The fossils are from the Cape Phillips Formation on Baillie-Hamilton and Cornwallis islands, and are part of the distinct biogeographic realm that stretches north and west of the Transcontinental Arch. The fossils were obtained from both allochthonous and autochthonous beds that represent slope or basin margin environments of the Franklinian Geosyncline. It describes 5 new genera and 19 new species.
