Comparison of the two finished arrowheads.

<p>Comparison of the two finished arrowheads.</p

Dagger (Maiolica, Lombard basin).

<p>a) Bioturbation (trace fossil). The microfacies is similar to the surrounding sediment, but darker due to the organic matter enrichment; b) Benthic crinoid stem ossicle in correspondence with the apical fracture; c-d, f) Radiolarians, sponge spicules, pelagic crinoids (<i>Saccocoma</i>), calpionellids, holoturians sclerites in a microcrystalline quartz and calcite matrix. Fe-Mn oxide spots and organic matter remains also occur. The not fully silicified chert has a microdetrital look; <b>e)</b> Radiolarians, partly filled with ferruginous mud, in a microcrystalline quartz matrix spotted by several tiny brownish calcite particles.</p

Arrowhead 14.

<p><b>Typological comparisons.</b> 1–2) CT-image and drawing of the Iceman arrowhead; 3, 7–9) Spilamberto; 4–5, 10) Remedello Sotto; 6) Scalucce di Molina; 11) Monte Loffa; 12) Palù di Cordignano; 13) Montello; 14–17) Vahrn; 18) Casarole; 19) Monte Aiona/Prato Mollo; 20) Sanguani; 21) Isera La Torretta; 22) Buca d’Andrea; 23) Ca’dei Grii; 24) Steinhausen-Sennweid; 25) Zürich-Kanalisationssanierung (Kantonsarchäologie Zürich); 26) Uebeschi-Subelmoos.</p

Endscraper.

<p>a) overstepping negatives made with pressure; b) endscraper front made with direct percussion; c) superimposition of fresh on glossy negatives. Upper right: distribution and intensity of gloss; red dots = location of small crushings.</p

Borer.

<p>blue arrow = oblique dorsal negative; L = Last detachment; red dots = location of use-wear; cross section with sequence of retouch; lower right left and right: details of crushings.</p

Use-wear on small flake.

<p>Use-wear polish from cutting vegetal material (soft wood or reeds) (560x).</p

Retoucher.

<p>a) the wooden handle and antler tip, b-c) detail of the radiological structure of the antler spike, displaying the cortical and the cancellous parts, d) CT image depicting its radiological structure.</p

Small flake.

<p>0 = remnant of ventral face of flake blank; ea = spontaneous negative; arrow = burin-like accident; red dots = location of use-wear.</p

Shape and radiological structure of natural antler points.

<p>a) red deer, b) roe deer (yearling), c) adult roe deer. Size comparison with the antler spike of Ötzi’s retoucher (red outline).</p
