Sd. Leroux et al., NONDESTRUCTIVE X-RAY-DIFFRACTION ANALYSIS OF CRANIAL BONE OF STS-5 (AUSTRALOPITHECUS AFRICANUS) AND ADHERING BRECCIA FROM STERKFONTEIN, SOUTH-AFRICA, South African journal of science, 93(4), 1997, pp. 173-174
X-my diffraction revealed the presence of crystalline hydroxyapatite a
s well as calcite in the mineralised bone of Sts 5. These results conf
