Book Description
Describes and illustrates 27 brachiopods, eight of which are new, from the lower shale member of Williams Island Formation sampled at the northeast bank of the Albany River, an unnamed island on the Abitibi River, and the south end of Mid-Bay Shoal in Hudson Bay. The report describes previous work conducted in the area and the quality of fossil material and problems of dating; the stratigraphy and biostratigraphy; brachiopod facies, communities, provincialism and paleogeography; and the systematic palaeontology.

Book Description
The Devonian was a peculiar period, characterized by simplified plate tectonic configurations, climatic overheating and widely flooded continents. The bloom of fishes and ammonoids, extensive reef complexes, and the conquest of land indicate major biosphere innovations, punctuated by many global events, including two of the biggest mass extinctions. The Devonian was the first system for which subdivisions were formally defined. This was achieved by significant advances in pelagic biostratigraphy. The chronostratigraphic framework and interdisciplinary techniques allow us to correlate intervals or sudden events across facies boundaries, in order to reconstruct the sedimentary and evolutionary history of the system with highest precision. This volume honors the lifetime stratigraphic achievements of Michael Robert House (1930-2002). Based on case studies from Europe, North Africa and North America, it shows how the combination of biostratigraphy, chemostratigraphy, magnetostratigraphy, sequence stratigraphy and event stratigraphy can contribute to a much deeper understanding of both regional and global environmental change.
