This book presents an assemblage of nineteen Paleozoic Crinoid species belonging to the family Melocrinidæ, providing a detailed description and illustration of each species. The author, a distinguished authority in the field, begins by introducing the taxonomic elements and structure of Crinoids. Following this, he delves into the specific characteristics and morphology of each species, noting each species' dimensions, ornamentation and composition. In addition, insights are offered on the phylogenetic relationships of these species to one another. This book serves as an invaluable guide for those seeking to understand these ancient echinoderms and their significance in enriching our knowledge of the Paleozoic era.

Paperback. Condizione: New. Print on Demand. This book delves into the diversity of invertebrate species that inhabited the ancient oceans of what is now the state of Illinois, from the Paleozoic (541-252 million years ago) to the Cenozoic (66 million years ago to the present day). The author's research, conducted with the Illinois State Museum, meticulously details previously undescribed species from various periods, including the Hamilton Group, Chouteau limestone, and Coal Measures. Fossils from each period are documented through illustrations and descriptions, divided into their respective classes: Lamellibranchs, Gastropods, Pteropods, and Cephalopods. The author also provides in-depth analysis of each species' morphology, geographical and geological distribution, and evolutionary significance within their broader taxonomic groups. A particular focus is given to the notable species Conularia roeperi, one of the largest known species within its genus. The author's work not only expands our understanding of the biodiversity of ancient marine life but also highlights the crucial role these creatures played in shaping the geological and fossil record of Illinois.

Paperback. Condizione: New. Print on Demand. This book introduces the latest findings from paleontologists S.A. Miller and W.F.E. Gurley, who discovered well-preserved fossils from sea creatures living in the Mississippi Valley from the Paleozoic Era. The authors describe an array of sea animals, ranging from giant, towering crinoids to smaller, less complex life forms, all having adapted to life on the shallow sea bottoms of that time. The animals detailed in this book are largely from the Burlington Group of the Mississippian Period, though discoveries from other rock strata are included as well. Meticulously illustrated, this book brings these extinct creatures back to life, demonstrating the amazing diversity of life on Earth millions of years ago.

Paperback. Condizione: New. Print on Demand. This book introduces the reader to newly discovered and intriguing species of Paleozoic fossils. The discoveries support the author's assertion that separating the genus Batocrinus into sub-groups or distinct genera based on the vault, azygous orifice, and arms is not natural or practical. The author maintains that the characteristics previously used for taxonomy instead demonstrate the diversity and vitality of Batocrinus across different species. Additionally, the author argues that what was once considered a generic attribute of Eretmocrinus can also be observed in Batocrinus, questioning the validity of these two distinct genera. The reader is invited to engage with this dialogue and consider the implications it holds for our understanding of echinoderms in the Paleozoic era.
