Describes the late Middle Devonian ostracodes found in two selected diamond drill cores from Lambton County, Ontario. The study area has lithologies and ostracode fauna typical of other similarly aged strata of the Michigan Basin, and the study permits stratigraphic correlation across an area extending over south-western Ontario, western New York, northern Ohio, and the southern peninsula of Michigan. The introductory sections discuss ostracode faunas of the Michigan Basin & bordering areas and the ostracode biostratigraphy of the Hamilton Group strata. The main section presents a systematic palaeontology of ostracode species, with species descriptions arranged by order, family, and genus.

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.
