Cephalopods Present and Past: New Insights and Fresh Perspectives


Book Description

This book brings together international scientists who focus on present-day and fossil cephalopods, ranging broadly from Paleozoic ammonoids to today's octopods. It covers systematics and evolution; hard- and soft part morphology; and ecology, biogeography, and taphonomy. The book also includes new evidence for the existence of an ink sac in fossil ammonoids and features the first record of an in-depth study of octopus ecology in Alaska.




Cenozoic Plants and Climates of the Arctic


Book Description

Fifty million years ago, the Arctic Ocean was a warm sea, bounded by lush vegetation of the warm-temperate shores of Scandinavia, Siberia, Alaska and the Northwest Territories. Wind and storms were rare because Atlantic weather systems had not developed but, as today, polar day length added a hostile element to this otherwise tranquil climate. With the aid of scientists from all the countries close to the Arctic Circle, this book describes the palaeontology, the statistical analysis of vegetational features, comparisons with atmospheric, marine, and geological features and some of the first models of plant migration developed from newly constructed databases.
