This atlas depicts skeletal features that are compiled to facilitate simple and direct access to some of the most interesting specimens currently known. This reference book is intended for clinicians, anatomists, anthropologists, forensic scientists, pathologists, biologists and other allied medical professionals who are fascinated with the expression of morphological features of the skeleton. It is particularly useful to the human biologist investigating genetic relatedness among and between skeletal samples utilizing non-metric trait analyses since this atlas provides a comprehensive visual guide for not only the identification and nomenclature of skeletal morphological features, but also for the appreciation of the range of anatomical expression. Photographic Regional Atlas of Non-metric Traits and Anatomical Variants draws from skeletal features observed from over 10,000 skeletons in collections throughout the world and provides a comprehensive yet concise presentation for rapid and reliable referral. Traits are arranged and presented based on skeletal region further facilitating ease-of-use for the reader when attempting to identify a feature of interest. Photographs are vividly displayed further enhancing the reader's ability to compare the standard reference to a desired feature. The authors draw on their own decades of experience in skeletal anatomy to provide the best photographic atlas available for referencing daunting anatomical variations and non-metric trait morphology. As a result, Photographic Regional Atlas of Non-metric Traits and Anatomical Variants provides a one-of-a-kind reference that serves as a crucial component in the pursuit of skeletal anomaly research and education.
