Summary
[edit]
| Description |
English: a, Aquila chrysaetos right humerus (layer 4) with superficial and straight cut mark clusters, associated with the removal of feathers. b, Crocuta crocuta ultima atlas (layer 10a), with an oblique cut mark generated during disarticulation. c, Marmota sp. (ZooMS taxon ID) radius diaphysis (layer 9), with a negative conchoidal medullary flake scar (black triangle) produced by anthropogenic breakage. d, A possible retoucher (layer 11). Equus sp. right lower P2 with a set of scrape marks on its buccal surface. e, Expedient bone tool (ZooMS taxon ID: Caprinae; layer 10b). This humerus diaphysis is deliberately shaped by continuous direct percussion (indicated by black triangles in the magnified image on the right) on its cortical surface. For all panels, the enlarged images (right in a,b,d,e and bottom in c) are magnifications of the regions denoted with dotted lines in the main images. Except where noted, taxonomic identifications are from morphological analysis. Scale bars, 2 cm (a–d, main images), 1 cm (e, main image) and 1 mm (all magnified images). |
