Abstract

Fossil reconstruction remains a requisite task for many types of paleoanthropological research. While reconstructions are traditionally accomplished by hand, computer modeling offers a novel and mathematically rigorous approach while providing advantages over the manual process. Computer models of fossil specimens can be reflected, scaled, and aligned in virtual space with relative ease; therefore, it is simple to generate multiple reconstructions to find the "best" one. Here we report on the reconstruction of A.L. 288-1ap (left femur) using three-dimensional computer models. Our "best" reconstruction has a maximum length of 277 mm, which is very near both the 280 mm originally estimated and the frequently cited 281 mm.
