Paperback. Etat : New. Print on Demand. This book delves into the fascinating world of trilobites, extinct marine arthropods that dominated the early Cambrian period. The author focuses on the Olenelloidea, a superfamily of trilobites that thrived in the ancient seas of Laurentia, the geological core of North America. Through a series of detailed phylogenetic analyses, the book meticulously examines the evolutionary relationships between different species of Olenelloidea, providing valuable insights into their diversification during the Cambrian radiation, a pivotal period in the history of life on Earth. The book presents compelling evidence for the existence of a significant evolutionary gap in the early history of the Olenelloidea, suggesting that the Cambrian radiation may have been even more explosive than previously thought. This book also highlights the need for a substantial revision of Early Cambrian biostratigraphy, particularly the Olenellus zone, which was traditionally based on a polyphyletic assemblage of trilobites. This analysis underscores the importance of using rigorous phylogenetic methods to understand the evolution and distribution of these ancient creatures.
