Paperback. Condition: New. Print on Demand. This book presents a detailed examination of Lower Silurian marine fossils in Canada, focusing on the Crinoidea (sea lilies). Sea lilies, particularly abundant during the Paleozoic era, held great scientific interest for centuries due to their distinct shapes that often resemble flowers. Although early naturalists speculated about their animal origins, it was only in the 1800s that their classification was refined and their body structures were mapped. The author provides a concise history of their identification, which includes distinguishing between their crowns and stems and classifying them by their plates. The text then discusses the detailed anatomy of these stalked echinoderms, including their plates, columns, and arms, with comprehensive terminology that can be applied to the fossils. The author also examines the function of their column, which attached some species to the seafloor while others were free-swimming, and the structure of the plates, which reveal the animals' unique respiratory and digestive systems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…
