Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1985 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Thirty-nine species of brachiopods from central and southeastern New York are systematically described. This monograph is based upon 7030 specimens collected from 30 localities and includes silicified as well as nonsilicified faunas. The following members of the Onondaga Limestone were sampled: Edgecliff, Nedrow, Moorehouse, and Seneca. The Onondaga thickens considerably toward the east with the greatest net change occurring in the Moorehouse Member (19 ft. near Syracuse to 92 ft. at Saugerties). The Seneca Member disappears just east of Cherry Valley and is not found in any strata of the mid-Hudson Valley. Crinoid columnals up to about 1 inch in diameter are characteristic of the Edgecliff Member across the state but become less abundant in the east. Brachiopod diversity is greatest in the Moorehouse Member and least in the Edgecliff Member. Of the 26 species of brachiopods in the underlying Bois Blanc Formation in western New York, nine occur in the Onondaga and show no evolutionary change. Morphologic variability in the Onondaga faunas was greater laterally than vertically. For the species studied here, the high degree of stasis in the Bois Blanc-Onondaga (Emsian-Eifelian) time interval may support a punctuational model as an evolutionary mode. During Eifelian time the faunas found in central and southeastern new York belonged to the Appohimchi Subprovince of the Eastern Americas Realm and were part of the larger suite extending westward across the continent. The Onondagan brachiopods reviewed here were provincial in character with the following genera endemic to the Appohimchi Subprovince: Charionoides, 'Pacificocoelia, ' and Pentagonia. Atribonium halli and Discomyorthis? sp. are the only species described herein not previously reported from Onondaga strata. No new species or genera were erected"--Page 293
