FIGURE 1. Left hyoid apparatus of the ground sloth Paramylodon harlani (modified from Stock, 1925). Shaded in grey is the fossil specimen analyzed in this work.
FIGURE 2. Juvenile stylohyal (CAV 476) in 1, medial view; 2, lateral view. The glittering of the cylindrical part is due to its having been bathed in gold for SEM observations; 3, close up of the cut mark analyzed by Fariña et al (2014); 4, close up of the marks in the midshaft. White arrows indicate probable trampling marks; black arrows indicate probable cut marks. Scale bar equals 50 mm.
