Book excerpt: Excerpt from The Supai Group: Subdivision and Nomenclature Probably the first geologist to carefully consider subdivision of the Supai Formation into logical, readily recognizable units was F. E. Matthes of the us. Geological Survey. In making a topographic map of the Bright Angel quadrangle in 1902-3, he noticed that the red beds of this formation, together with the overlying Hermit Shale, characteristically eroded into three prominent cliffs, interspersed among four well developed slopes. The discrimination of these topographic units was called to my attention by Matthes in the 1930's in connection with my studies of the Supai Formation. A field classification that proved useful in recording data at that time and in all subsequent work resulted. Subdivision of the Supai on the basis of topographic expression, used during the present field-investigation, recognized the following units: Upper cliff unit, locally includes a receding ledge unit (esplanade cliff) About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.
