Trilobites are fascinating creatures that ruled the early Paleozoic seas. These arthropods first appeared in the Cambrian Period, lived for hundreds of millions of years and went extinct at the end of the Permian Period, around 251 million years ago, before the arrival of the dinosaurs. Trilobites lived in a variety of marine environments ranging from shallow tropical seas to the depths of polar oceans and were distributed globally.
The remains of trilobites are ubiquitous in Paleozoic era sedimentary rocks of North America and are found throughout Southern Ontario, Canada, with trilobites also being found in neighboring Quebec and New York State. Ordovician Trilobites Of Southern Ontario, Canada And The Surrounding Region illustrates some of the best preserved Ordovician trilobites of the region and provides a thorough description of the trilobite species found in Southern Ontario.
This book will appeal to anyone interested in Paleozoic fossils and trilobites, from academics to beginning amateur and seasoned collectors. Ordovician Trilobites Of Southern Ontario, Canada And The Surrounding Region is a comprehensive regional guide that explores an important part of Canada's early geological history.
