Abstract
The Taung endocast is one of the bestβpreserved and most important known in paleoanthropology. Although the endocast is undistorted and preserves distinctive landmarks, Taung has proved a difficult endocast, because it is only about 60% complete. To reconstruct Taung it is necessary to first use the available anatomical landmarks to define the midline of the endocast. It is only with a proper description of the midline that it is possible to reconstruct the endocast and obtain an accurate measurement of Taung's endocranial volume. Holloway (Science 168 (1970) 966β968) determined a conservative estimate for Taung of 404 ml. More recently this estimate has been revised downward by Falk and Clarke (Am J Phys Anthropol 134 (2007) 529β534) to 382 ml, giving Taung the smallest endocast for A. africanus. Certain challenges exist with the reconstruction of any endocast, particularly a hemiβendocast such as Taung. A virtual reconstruction of Taung must assume perfect symmetry, a feature called into question here in Taung's most recent reconstruction by Falk and Clarke (2007). Holloway's (1970) reconstruction of Taung provides a guidepost for a conservative approach to endocast reconstructions, and the most reliable measurement of Taung's true endocranial volume.

Using a n independent method of direct tape-arc measurements on six chimpanzee brain casts, it is shown that Falk's (1980, 1983) claims regarding a n anterior pongidlike placement of a lunate sulcus on the Taung specimen remain unconfirmed. Thus Holloway's (1981) stereoplotting method of testing Fal
