Please be sure to read the License for viewing and use of these files.

These data accompany the article, Kappelman, J. et al. 2024. Adaptive foraging behaviors in the Horn of Africa during Toba supereruption. Nature (https://doi.org/10.1038/s41586-024-07208-3) with the URL link found in the Supplementary Information. The files include 3D scans for 13 projectile points from Shinfa Metama 1 (SM1), a Middle Stone Age site dated to ~74 ka located in northwestern Ethiopia.

On each page of the large pdf file, "Kappelman SI SM1 Points 3D File Photos Drawings.pdf," the 3D scans of the objects are interactive. Open the file in Adobe Reader. The grey image of the point at left is an interactive 3D object. Place the cursor on the point and left click the mouse to activate. In a few seconds, a menu bar will open above the image. Place the cursor on the point, hold down the left mouse button to grab the point, and move the mouse around to rotate and turn, roll the scroll wheel to zoom in/out, and use the features of the menu to view cross-sections, etc. Photographs of the dorsal and ventral surfaces are included at upper right of each page, with drawings shown at lower right. See Supplementary Table 6 for measurements and full descriptions. See the ‘Digital photography, drawings, 3D scanning, and interactive 3D objects’ section of the Methods for additional information.

The other 13 files in the .ply format can be downloaded for viewing and 3D printing. These points are illustrated in Fig. 3 in the Nature article.
