1 Review
This best-selling historical geology text provides geologists with an excellent balance of basic geology and paleontology. The ninth edition presents rich, authoritative coverage of the history of the Earth, offering the most comprehensive history in the discipline today. It maintains its strong approach to stratigraphy and paleontology that other texts have lost. The text's paleogeographic maps are excellent in detail and are a vital component in understanding the earth's history. Stunning artwork brings the ancient world to life. Geology of National Parks boxes encourage them to visit these parks to appreciate their geological significance. Geologists will also appreciate the questions about past geologic events and the processes used in finding answers.

About the author (2009)

Atala Dorothy Toy is a specialist in interdimensional communication — a spiritual science that enables humans to communicate with life forms existing in frequency ranges different from human ones. She is the founding president of Crystal Life Technology, Inc., a cutting edge company established in 1996 to provide the public with consciousness expanding products, jewelry, information and photographs.

A severe bout of environmental illness in the mid-1990s was the trigger that brought her into communication with a group of spirit guides who worked with her to locate methods to cure herself. From this time forward, she has worked to develop products, modalities, photographs and information on how to communicate and cooperate interdimensionally.

Atala has written extensively on consciousness in various magazine articles and in three books, and has begun showing others how to develop their own personal abilities to communicate interdimensionally according to their particular strengths — an effort that has led her to conduct workshops, offer private consultations, author articles and blogs, and teach others how to take actual photographs of life forms of other realms.

A graduate of Swarthmore College, Atala has worked in publicity at the Massachusetts Institute of Technology, as the submissions editor for Doubleday & Co., and in public relations at the United Nations Development Programme. Her volunteer work has included serving as Secretary of the Board of the American Society of Dowsers and as President of the Board of the Institute for the Study of Interdimensional Cooperation.

Atala is also a 35-year meditative yoga practitioner. She currently resides in a suburb of Chicago.
