Fossil preservation, ontogenetic age, and sex of Malapa hominins Recent discoveries at the site of Malapa include associated craniodental and postcranial remains of at least two individuals. The two skeletons were found in the same stratigraphic horizon, dated to between 1.95-1.78 Ma, and separated from one another by no more than half a meter horizontally. The remains of one individual (MH2) were recovered in partial articulation, while those of the other (MH1) were somewhat more disturbed, yet still in close association (distributed over an area of less than 2 m2). The majority of the hominin fossils are in very good condition, and this, combined with the spatial distribution of the skeletons, the partial articulation of one individual (and of some of the associated faunal remains), and the geological context indicates rapid deposition and contemporaneity of the two hominin individuals (1). MH1 is a partial skeleton preserving much of the cranium and a partial mandible, maxillary and mandibular teeth, and portions of the postcranial axial skeleton, pectoral girdle, upper limb, pelvic girdle, and lower limb (Table S1). The first element of MH1 found (UW 88-1, clavicle) was discovered by M
