Stephen Jay Gould borrowed from Winston Churchill when he described the conodont animal as a "riddle wrapped in a mystery inside an enigma." This animal confounded science for more than a century. Some thought it a slug, others a fish, a worm, a plant, even a primitive ancestor of ourselves. The list of possibilities grew and yet an answer to the riddle never seemed any nearer. Would the animal that left behind these miniscule fossils known as conodonts ever be identified? Three times the animal was "found," but each was quite a different animal. 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.

Written for everyone fascinated by the huge beasts that once roamed the earth, this book introduces the giant hornless rhinoceros, Indricotherium. These massive animals inhabited Asia and Eurasia for more than 14 million years, about 37 to 23 million years ago. They had skulls 6 feet long, stood 22 feet high at the shoulder, and were twice as heavy as the largest elephant ever recorded, tipping the scales at 44,100 pounds. Fortunately, the big brutes were vegetarians. Donald R. Prothero tells their story, from their discovery just a century ago to the latest research on how they lived and died.

Palaeontology, the scientific study of fossils, has developed from a descriptive science to an analytical science used to interpret relationships between earth and life history. This book provides a comprehensive and thematic treatment of applied palaeontology, covering the use of fossils in the ordering of rocks in time and in space, in biostratigraphy, palaeobiology and sequence stratigraphy. Robert Wynn Jones presents a practical workflow for applied palaeontology, including sample acquisition, preparation and analysis, and interpretation and integration. He then presents numerous case studies that demonstrate the applicability and value of the subject to areas such as petroleum, mineral and coal exploration and exploitation, engineering geology and environmental science. Specialist applications outside of the geosciences (including archaeology, forensic science, medical palynology, entomopalynology and melissopalynology) are also addressed. Abundantly illustrated and referenced, Applications of Palaeontology provides a user-friendly reference for academic researchers and professionals across a range of disciplines and industry settings.

From the outwash plains of Brooklyn to Indiana's drifted diamonds and gold, John McPhee's In Suspect Terrain is a narrative of the earth, told in four sections of equal length, each in a different way reflecting the three others-- a biography; a set piece about a fragment of Appalachian landscape in illuminating counterpoint to the human history there; a modern collision of ideas about the origins of the mountain range; and, in contrast, a century-old collision of ideas about the existence of the Ice Age. The central figure is Anita Harris, an internationally celebrated geologist who went into her profession to get out of a Brooklyn ghetto. The unifying theme is plate tectonics-- here concentrating on the acceptance that all aspects of the theory do not universally enjoy. As such, In Suspect Terrain is a report from the rough spots at the front edge of a science. In Suspect Terrain is the second book in a series on geology and geologists, presenting a cross section of North America along the fortieth parallel, and gathered under the overall title Annals of the Former World. The other books in the series are Basin and Range, Rising from the Plains, and Assembling California.
