Available in PDF, EPUB and Kindle. Book excerpt: This volume, aimed at the general reader, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long history.

Download or read book Geology of Millard County Utah written by Lehi F. Hintze and published by Utah Geological Survey. This book was released on 2003 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Indexes the world's zoological and animal science literature, covering all research from biochemistry to veterinary medicine. The database provides a collection of references from over 4,500 international serial publications, plus books, meetings, reviews and other no- serial literature from over 100 countries. It is the oldest continuing database of animal biology, indexing literature published from 1864 to the present. Zoological Record has long been recognized as the "unofficial register" for taxonomy and systematics, but other topics in animal biology are also covered.

Download or read book Evolution and Phylogeny of Pancrustacea written by Frederick R. Schram and published by Oxford University Press. This book was released on 2021-11-02 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scientific understanding of arthropod phylogeny and evolution has changed significantly in recent decades. One of the most momentous alterations involved crustaceans, which are not a monophyletc group, but are part of a larger group along with insects: Pancrustacea. The old ideas surrounding crustacean evolution have served scientists well for many years; it is now time to turn toward new research by embracing the results derived from investigations conducted largely within this century. For example, new definitions have arisen from sources across several fields of study, and Frederick R. Schram and Stefan Koenemann have created a book that explores paleobiodiversity and the diversity of modern body plans. Developments within ontogenetic studies continue to generate remarkable insights into crustaceomorph evolution in regard to patterns of embryology and a revolution in the application of development genetics. Phylogeny techniques of analysis and new sources of data derived from molecular sequencing and genetic studies have forced scientists to consider new hypotheses concerning the interrelationships of all the pancrustaceans, both the crustaceomorphs and Hexapoda. Yet, some fossil groups still remain enigmatic (Thylacocephala). Despite this, research into fossils (even if incompletely understood) fills in gaps of our knowledge of paleobiodiversity, and it's useful for many things, including analyzing the origin and early evolution of Hexapoda. Evolution and Phylogeny of Pancrustacea demonstrates the use of multiple alternative hypotheses and other techniques through the well-executed presentation of diverse data sources involving Pancrustacea. Readers are left with clues to great mysteries, including the possible pathways of evolution within marine arthropods.
