A New Silurian (Llandovery, Telychian) Sponge Assemblage from Gotland, Sweden
Author: Freek Rhebergen
Publisher: John Wiley & Sons
ISBN: 1118906640
Category : Science
Languages : en
Pages : 161
Book Description
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.

Receptaculitids
Author: Matthew H. Nitecki
Publisher: Springer Science & Business Media
ISBN: 1461546915
Category : Science
Languages : en
Pages : 249
Book Description
Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of Öland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil.
