The anatomical record : advances in integrative anatomy and evolutionary biology

The goals of this study were (1) to provide accessible and instructive browsing software for sectioned images and a portable document format (PDF) file that includes three-dimensional (3D) models of an entire dog body and (2) to develop techniques for segmentation and 3D modeling that would enable an investigator to perform these tasks without the aid of a computer engineer. To achieve these goals, relatively important or large structures in the sectioned images were outlined to generate segmented images. The sectioned and segmented images were then packaged into browsing software. ⋯ The browsing software and PDF file are available for study by students, for lecture for teachers, and for training for clinicians. These files will be helpful for anatomical study by and clinical training of veterinary students and clinicians. Furthermore, these techniques will be useful for researchers who study two-dimensional images and 3D models.

There is almost a universal fascination with prehistoric, protohistoric, and historic human remains that preserve the soft tissues (nonskeletal) of the body (general definition of a mummy). While most people within the general public engage with mummies as part of a museum exhibit process, many scientists have taken that fascination much further. ⋯ This issue of the Anatomical Record was conceived and formulated to bring together a series of researchers to highlight their most groundbreaking research on the scientific advances that surround the 21st Century AD study of these preserved biological beings including an illumination of the cultural processes that purposefully or inadvertently are preserved either within their tissues or are present within the context (archaeological) in which they are found (excavated). Twenty-six research articles are presented in this volume on a variety of topics all related to the rich transdisciplinary fields that are now directing their research efforts to the state-of-the art analysis of human mummified remains.

Mummification leads to alteration of soft-tissue morphology. No research has focused specifically on differences in soft-tissue shrinkage depending on mummification type. This study evaluated whether soft-tissue alteration is dependent on type of mummification. ⋯ Variation between different anatomical structures (e.g., upper lip vs. mid-femur) is significant, unlike variation within one compartment (e.g., proximal vs. distal humerus). Mummification type strongly affects the degree of soft-tissue alteration, surprisingly mostly independent of overall historical age. These results highlight the unique morphological impact of taphonomy on soft-tissue preservation and are of particular interest in tissue research as well as in forensics.

Computed tomography scanning of mummies has been conducted for almost 40 years, and has become an increasingly popular method of mummy study in the 21st century. However, most CT scan analyses published today still do little more than praise the technique's non-destructive, non-invasive properties. ⋯ Because of this, there is very limited information available for clear interpretation of mummy CT's. This article presents a critical assessment of the development of mummy CT scanning and presents the results of two Egyptian mummies CT'ed at the Penn Museum as an example of the potentials and pitfalls of high-resolution scanning.

In May of 1994, Drs. Bob Brier and Ronn Wade produced the first modern mummy embalmed in the ancient Egyptian tradition. ⋯ The radiological study of MUMAB is combined here with the firsthand discussion of the processes that resulted in the mummy's radiographic appearance. This allows for a close examination of the assumptions made in the radiological study of ancient Egyptian mummified human remains in a way not possible for the ancient remains themselves.
