Hosted by the University of Texas at Austin, this resource aims to facilitate the teaching of anatomy by providing three dimensional images and animations of the human skeleton and other primates, including gorillas, chimpanzees and orangutans. The site is clearly laid out and easy to use, and the quality of the images - which were created with the use of a 3D laser scanner, high resolution X-ray computed tomography (HRXCT) and digital photography - is outstanding. The site’s interface allows information about the bones and how they attach to muscles to be turned on and off. Also of interest, and built on similar principles, is sister-site eLucy, which is devoted to the remains of a member of the species Australopithecus afarensis, whose skeleton is one of the most complete australopithecine fossils ever found.
