Earth and Life
This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated.
Monarchs of the Sea: The Extraordinary 500-Million-Year History of Cephalopods
From the author of Nursery Earth, a “nimble, fast, surprising, smart, and weird in the very coolest sense of the word” (Sy Montgomery) exploration of the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs—a Science Friday Book Club Pick Cephalopods, Earth’s first truly substantial animals, are still among us: Their fascinating family tree features squid, octopuses, nautiluses, and more. The inventors of swimming, cephs presided over the sea for millions of years. But when fish evolved jaws, cephs had to step up their game (or end up on the menu). Some evolved defensive spines. Others abandoned their shells entirely, opening the floodgates for a tidal wave of innovation: masterful camouflage, fin-supplemented jet propulsion, and intelligence we’ve yet to fully measure. In Monarchs of the Sea, marine biologist Danna Staaf unspools how these otherworldly creatures once ruled the deep—and why they still captivate us today. Publisher’s Note: Monarchs of the Sea was previously published in hardcover as Squid Empire.
Geologic Time Scale 2020
Geologic Time Scale 2020 (2 volume set) contains contributions from 80+ leading scientists who present syntheses in an easy-to-understand format that includes numerous color charts, maps and photographs. In addition to detailed overviews of chronostratigraphy, evolution, geochemistry, sequence stratigraphy and planetary geology, the GTS2020 volumes have separate chapters on each geologic period with compilations of the history of divisions, the current GSSPs (global boundary stratotypes), detailed bio-geochem-sequence correlation charts, and derivation of the age models. The authors are on the forefront of chronostratigraphic research and initiatives surrounding the creation of an internatio...
Squid Empire
Before there were mammals on land, there were dinosaurs. And before there were fish in the sea, there were cephalopods-the ancestors of modern squid and Earth's first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean's former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned th...
Cephalopods Present and Past: New Insights and Fresh Perspectives
Cephalopods are diverse, highly developed molluscs capable of swimming and jet propulsion. These animals are an important component of present-day marine ecos- tems throughout the world and comprise approximately 900 species. They also have an extraordinary fossil record, extending back to the Cambrian Period, with as many as 10,000 extinct species. Throughout their long history, they have experienced sp- tacular radiations and near-total extinctions. Because of their superb fossil record, they also serve as ideal index fossils to subdivide geologic time. This book touches on many of these themes, and it treats both fossil and present-day cephalopods. The chapters are outgrowths of presentat...

Palaeontology and Facies of the Late Famennian in the Paffrath Syncline (Rhenish Massif, Germany)
This volume contains 16 papers that all deal with the Refrath 1 Borehole. This borehole is located in the Bergisch Gladbach-Paffrath Syncline (Ardennes-Rhenish Massif, Germany) specifically to study the poorly known Upper Devonian (Famennian) sediments. The borehole was funded by the Geological Survey of North Rhine-Westphalia. Although the initial emphasis was on the regional geology and the geological mapping, the discovery in the borehole of many different fossil groups initiated research on palaeontology and biostratigraphy together with sedimentology, facies, thermal maturity and organic geochemistry. Hence, this volume on the Refrath 1 Borehole clearly demonstrates how a seemingly routine Geological Survey NRW geological and engineering geological mapping project triggered a multi-disciplinary research project whose results are of international interest.
