The Malapa site has yielded unusually abundant and well preserved fossils of Australopithecus sediba. While some elements were found in situ during excavation, others were recovered ex situ from blocks of clastic, calcified sediments collected around the site. We have refitted the ex situ elements from Facies D, the sedimentary unit represented by a single debris flow from which most of the Au. sediba remainswere collected, with the elements recovered in situ. Results confirm that the fossils in this unit can securely be attributed to two near-complete skeletons of a juvenile male (MH1), which initially lay in the upper, laminated part of Facies D, and an adult female (MH2), deposited in the lower part of this facies. We propose a description of peri- and postmortem events based on the location and orientation of the fossils, using for the first time a 3D reconstruction of the postulated position in which the two hominins were deposited. Macro- and microscopic modifications of bone surfaces, and degree of preservation confirm that the individuals were washed into the deposit as articulated—or semi-articulated—complete bodies, which were subaerially exposed for some time, and had reached natural mummification before being deposited within a debris flow.
