South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the “Great American Biotic Interchange” (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South Am…
This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number o…

New material attributable to Deltasuchus motherali, a neosuchian from the Cenomanian of Texas, provides sampling across much of the ontogeny of this species.
This volume provides an overview of (1) the physical and chemical foundations of dating methods and (2) the applications of dating methods in the geological sciences, biology, and archaeology, in almost 200 articles from over 200 international authors. It will serve as the most comprehensive treatise on widely accepted dating methods in the earth sciences and related fields. No other volume has…
The emphasis in this volume is on the structure and functional design of the integument. The book starts with a brief introduction to some basic principles of physics (mechanics) including Newton’s Three Laws of Motion. These principles are subsequently used to interpret the problems animals encounter in motion. It is in only the last 40 or so years that we have begun to understand how imp…
Reporting on a multi-disciplinary project this book seeks to reconstruct the history since the last glaciation of the area between and including the middle reaches of the Rivers Swale and Ure in Yorkshire. Included in this history are both natural changes, determined from studies of landforms and sediments, and human-induced changes, recorded in archaeological and geo-archaeological records. Th…
Lev Tolstoy has held the attention of mankind for well over a century. A supremely talented artist, whose novels and short stories continue to entrance readers all over the world, he was at the same time a fearless moral philosopher who explored and challenged the fundamental bases of human society—political, economic, legal, and cultural. Hugh McLean, Professor Emeritus of Russian literature…
