Download and read online ebook Trilobites of Black Cat Mountain write by George P. Hansen. This book was released on 2009-03-04. Trilobites of Black Cat Mountain available in PDF, EPUB and Kindle. A photographic guide to Oklahomas Devonian trilobites. The geological history of Coal County, Oklahoma. Descriptions of rock formations where trilobites are found. Excavation and restoration of trilobites. A photographic atlas of the Lower Devonian trilobites of Oklahoma, with helpful information to aid in their identification. Trilobites are a well-known fossil group, possibly second most famous only to dinosaurs. With their easily fossilized exoskeleton, they left an extensive and diverse fossil record. They began a drawn-out decline to extinction during Late Devonian time, when all but one of the trilobite orders died out. This meticulously researched reference guide is a photographic atlas and descriptive compendium on the trilobites of Coal County, Oklahoma. The species described lived during the Lower Devonian in a shallow tropical ocean that had advanced over the landscape of North America. More than twenty species are exquisitely preserved in Oklahomas limestone rocks. Each species is carefully illustrated, including thorough descriptions, so that those familiar and unfamiliar can understand and appreciate these amazing creatures. The most current scientific research on these trilobites is also included. For those wishing to pursue a deeper interest in trilobites, a comprehensive bibliography lists hundreds of sources of information for further study.

Spying on Whales available in PDF, EPUB and Kindle. “A palaeontological howdunnit…[Spying on Whales] captures the excitement of…seeking answers to deep questions in cetacean science.” —Nature Called “the best of science writing” (Edward O. Wilson) and named a best book by Popular Science, a dive into the secret lives of whales, from their four-legged past to their perilous present. Whales are among the largest, most intelligent, deepest diving species to have ever lived on our planet. They evolved from land-roaming, dog-sized creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and travel entire ocean basins. Whales fill us with terror, awe, and affection--yet there is still so much we don't know about them. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea--and what can their lives tell us about evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive? Nick Pyenson's research has given us the answers to some of our biggest questions about whales. He takes us deep inside the Smithsonian's unparalleled fossil collections, to frigid Antarctic waters, and to the arid desert in Chile, where scientists race against time to document the largest fossil whale site ever found. Full of rich storytelling and scientific discovery, Spying on Whales spans the ancient past to an uncertain future--all to better understand the most enigmatic creatures on Earth.
Geology of Millard County, Utah

Download and read online ebook Geology of Millard County, Utah write by Lehi F. Hintze. This book was released on 2003. Geology of Millard County, Utah available in PDF, EPUB and Kindle. This bulletin serves not only to introduce the non-geologist to the rich geology of Millard County, but also to provide professional geologists with technical information on the stratigraphy, paleontology, and structural geology of the county. Millard County is unique among Utah’s counties in that it contains an exceptionally complete billion-year geologic record. This happened because until about 200 million years ago the area of present-day Millard County lay near sea level and was awash in shallow marine waters on a continental shelf upon which a stack of fossil-bearing strata more than 6 miles (10 km) thick slowly accumulated. This bulletin summarizes what is known about these strata, as well as younger rocks and surficial deposits in the county, and provides references to scientific papers that describe them in greater detail. Mountains North 30 x 60 (1:100,000-scale) quadrangles. These companion maps and this bulletin portray the geology of Millard County more completely and accurately than any previously published work.
