APPENDIX 6 in New associated postcranial remains from the Shungura Formation (Lower Omo Valley, Ethiopia) provide insights on behaviors and ecology of early Homo

APPENDIX 6. — Comparison of the morphology of OMO VE 3-10063 with that of selected hominins and Pan troglodytes. Abbreviations: AP, anteroposterior; NA, not available; SI, superoinferior. Notes: a, as represented by D4161, D4162, KNM-WT 15000 C and D (clavicle); D4166, KNM-WT 15000 E (scapula); KNMWT 15000 F, D2715, D2680, D4507 (proximal humerus); KNM-WT 15000 F, D2715, D2680, D4507, IB 7594 (distal humerus);KNM-WT 15000 R (spinous process of the vertebra); KNM-WT 15000 CB, AP, AU, AO, BD-BE-BJ, AK, AL, AM, AS (rib); b, as represented by OH 48 (clavicle); KNM-ER 3735 (distal humerus); c, as represented by KNM-ER 47000 (scapula);KNM-ER 739, KNM-ER 1504, KNM-ER 6020, KNM-ER 45510, TM 1517, SK 24600 (distal humerus); d, as represented by U.W. 88-1, U.W. 88-38, A.L. 333x6/9, KSD-VP 1/1, StW 431, StW 573 (clavicle), KSD-VP 1/1 only for the relative sternal curvature; U.W. 88-56, A.L. 288-1, KSD-VP 1/1, StW 431, Sts 7, StW 573 (scapula); Sts7, U.W. 88-101, U.W. 88-57, A.L. 288-1r, A.L. 288-1m, A.L. 333-87, A.L. 333-107 (proximal humerus); A.L. 288-1, A.L. 137-48a, A.L. 322-1, A.L. 333-29 (distal humerus); U.W. 88-09 (spinous process of the vertebra); A.L. 333-106, KSD-VP 1/1 (vertebral body); A.L. 288-1, KSD-VP 1/1, U.W. 88-45, 46, 47, 48, 59, 60, 61 (rib); e, KNM-WT 15000 only; f, StW 573 only; g, in lateral view; h, the character coding was based on the information and images published in Green et al. 2018, as we did not have access to scans of KNM-ER 47000; i, concern A. sediba only because of a poorly preserved fossil record for other Australopithecus species; j, defined as the length of the radius of sternal curvature relative to the radius of acromial curvature (cf. Methods); k, transverse width relative to the SI height; l, SI height relative to transverse breadth.
