From: Cultural innovation and megafauna interaction in the early settlement of arid Australia
A, Comparison between the Diprotodon bone (EMU RS-6737-7754) from Warratyi rock shelter and juvenile radius specimens of D. optatum from the South Australian Museum (SAMA P51340–P51342). Aa, EMU RS-6737-7754 in anterior view. Ab, View of the broken distal end of EMU RS-6737-7754. Ac, EMU RS-6737-7754 in posterior view. Ad, View of the broken proximal end of EMU RS-6737-7754. Ae, View of the broken distal end of SAMA P51340. Af, SAMA P51340 in posterior view. Ag, View of the broken proximal end of SAMA P51341. Ah, View of the broken distal end of SAMA P51341. Ai, SAMA P51341 in posterior view. Aj, View of the broken proximal end of SAMA P51340. Ak, SAMA P51342 in posterior view. The silhouette represents the approximate corresponding position for EMU RS-6737-7754. Scale bars, 20 mm. The top scale bar is for panels Aa–Aj; the bottom scale bar is for panel Ak. B, Micro-computed tomographic images comparing EMU RS-6737-7754 with a juvenile radius specimen of D. optatum. Ba, Isosurface rendering of EMU RS-6737-7754 showing the position of a more proximal cross-section. Bb, Isosurface rendering of EMU RS-6737-7754 showing the position of a more distal cross-section. Bc, Isosurface rendering of SAMA P51341 showing the position of the cross-section. Bd, More proximal cross-section of EMU RS-6737-7754 (as shown in Ba). Be, More distal cross-section of EMU RS-6737-7754 (as shown in Bb). Bf, Cross-section of SAMA P51341 (as shown in Bc). Bg, Longitudinal-section of EMU RS-6737-7754. Bh, Longitudinal-section of a portion of SAMA P51341. Scale bars, 20 mm. C, Taphonomic markings on the surface of EMU RS-6737-7754.
