Pyle and published by NRC Research Press. This book was released on 2002 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conodonts, the tiny, phosphatic, tooth-like remains of an extinct group of early vertebrates, are the most important fossil group for biostratigraphy throughout their stratigraphic range from Late Cambrian to Late Triassic. This monograph represents a benchmark study of these important zonal fossils. The detailed paleontological work not only provides a taxonomic basis for future studies on early Paleozoic conodonts but also focuses on the evolution of conodonts in the early Ordovician, a time of extraordinary adaptive radiation. The taxonomic work provides detailed descriptions and illustrations of 185 species representing 69 genera. Seven new genera and 39 new species are described. The high diversity of taxa across the platform-to-basin transect shows the biogeographic differentiation and spatial ecological partitioning of conodonts through time. The taxonomy permits the refinement to the biostratigraphic zonation within two faunal realms for British Columbia that can be correlated with schemes elsewhere in North America and also internationally.

Available in PDF, EPUB and Kindle. Book excerpt: A fascinating, comprehensive, accessible account of conodont fossils—one of paleontology’s greatest mysteries: “Deserves to be widely read and enjoyed” (Priscum). Stephen Jay Gould borrowed from Winston Churchill when he described the eel-like conodont animal as a riddle wrapped in a mystery inside an enigma. The search for its identity confounded scientists for more than a century. Some thought it a slug, others a fish, a worm, a plant, even a primitive ancestor of ourselves. As the list of possibilities grew, an answer to the riddle never seemed any nearer. Would the animal that left behind the miniscule fossils known as conodonts ever be identified? Three times the creature was found, but each was quite different from the others. Were any of them really the one? Simon J. Knell takes the reader on a journey through 150 years of scientific thinking, imagining, and arguing. Slowly the animal begins to reveal traces of itself: its lifestyle, its remarkable evolution, its witnessing of great catastrophes, its movements over the surface of the planet, and finally its anatomy. Today the conodont animal remains perhaps the most disputed creature in the zoological world.

Available in PDF, EPUB and Kindle. Book excerpt: One of the leading textbooks in its field, Bringing Fossils to Life applies paleobiological principles to the fossil record while detailing the evolutionary history of major plant and animal phyla. It incorporates current research from biology, ecology, and population genetics, bridging the gap between purely theoretical paleobiological textbooks and those that describe only invertebrate paleobiology and that emphasize cataloguing live organisms instead of dead objects. For this third edition Donald R. Prothero has revised the art and research throughout, expanding the coverage of invertebrates and adding a discussion of new methodologies and a chapter on the origin and early evolution of life.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Zoological Micropalaeontology, Volume II focuses on the study of microfossils. The book first discusses the nature and characteristics of sponges, including the morphology and main groups of sponge spicules, modifications of the shape of sponge spicules, and arrangement of skeletal elements. The text also looks at octocorals and scolecodonts. The taxonomic relationships of the melanoscleritoids; anatomy of the anterior part of the digestive system tract of polychaeta; and classification of scolecodonts are described. The selection also touches on conodonts. Topics include morphology; phylogeny of lamellar conodonts; and geological distribution of conodonts and their value in correlation. The text also examines ostracoda and echinodermata, including reproduction, sexual dimorphism, ecology of ostracods, and skeletal elements of crinoidea, echinoidea, and holothuroidea. The book also discusses otoliths. Topics include nomenclature and morphology of otoliths; geological distribution and value of otoliths, and history of research. The text is a good source of information for readers interested in fossils.
