JUVENILE HOMINID SPECIMENS FROM SWARTKRANS 53 SPECIMEN SK 852 This specimen was excavated from Member 1 breccia by J. T. Robinson in 1952. The description on the catalogue card reads: 'Poor specimen of juvenile mandible with left dm2 (broken); dm2, moderately worn; right dm! appreciably worn; dm2 moderately worn and incomplete; and fragment of Mx erupting.' Prior to cleaning and restoration, this specimen consisted of an isolated and nearly complete Rdc as well as the isolated, complete crowns of the Llu LI2 and LC. The major part of this specimen consisted of the poorly preserved mandibular corpora with the roots of the Ldml5 the damaged Rdml5 Ldm2, Rdm2 and the metaconid of the RMb and the matrix-covered crown of the LM, (Fig. 6). The mandibular corpora were preserved in misalignment, and wedged. Fig. 6. Stereoview of the mandibular corpora and dentition of SK 852 prior to restoration. Compare with Figure 8. Scale in cm. between them was a large piece of unidentified bone. The region of the RMX was covered in plaster. The two corpora were removed from the matrix and cleaned. In this process the hypoconid and hypoconulid of the RM, were discovered beneath the plaster; this piece of crown was reconstructed in correct anatomical position. The corpora and their contained teeth were cleaned and, where necessary, strengthened with plaster. The mandibular corpora are poorly preserved, somewhat distorted and very incomplete. Meaningful descriptions or measurements for either of these are not possible (see Figs 8 and 10)..
