<b>Ethne Barnes</b> is well known for her 1994 book, <i>Developmental Defects of the Axial Skeleton</i>, still widely in use today. A recognized specialist in the area of skeletal defects, Dr. Barnes is probably the premier expert in congenital defects of the central part of the skeleton. Currently she works as Physical Anthropologist / Paleoanthropologist for Corinth Excavations, ASCS in Tucson Arizona.

<p><b>A unique illustrated guide for identifying, understanding, and interpreting developmental field anomalies in the human skeleton</b></p> <p>This highly visual guide provides a quick and easy reference to the developmental defects of the human skeleton. Using numerous illustrations accompanied by brief descriptions, <i>Atlas of Developmental Field Anomalies of the Human Skeleton</i> introduces readers to the embryological development of the skeleton within its various developmental fields, reveals how variations occur during embryogenesis, and clearly shows how to interpret skeletal anomalies without confusing them with disease or trauma.</p> <p>Built upon the morphogenetic approach to skeletal analysis advanced by Dr. Barnes in her groundbreaking work, <i>Developmental Defects of the Axial Skeleton,</i> this volume brings all information up to date and extends coverage to anomalies in both the axial and appendicular parts of the skeleton. The only book on the market to examine developmental field anomalies for the entire skeleton from head to toe, this picture atlas:</p> <ul> <li>Emphasizes areas where a paleopathological approach is superior to medical constructs or DNA studies</li> <li>Illustrates each part of the skeleton's embryonic development and compares various anomalies with normal counterparts</li> <li>Employs a well-ordered classification system for defining skeletal variations and identifying new anomalies</li> <li>Highlights the role of genetics in affecting skeletal structural variations</li> <li>Reviews in the book's Introduction the morphogenetic approach developed by the author</li> </ul> <p>Clearly organized and delightful to use, this illustrated work is an essential resource for skeletal biologists as well as medical specialists in skeletal disorders, archaeologists, and general readers.</p>
