These are prehistoric bone tools used by prehistoric humans, or “Cultural additions from the double grave of Oberkasssel,” as the title reads in German. The caption from Wikimedia Commons, where I found this file, reads in English:

Figure 1 (Pictures 1 – 4 from left) – Max Verworn, in 1919, called the figure “Smoothing Tool” (Lissoir)
Figure 2 (pictures below left, right + above) – “Animal head carving”
Figure 3 (pictures 5 – 7) – “unprocessed, awl-shaped animal bones”

Besides these tools, one of the most interesting things found in the excavations near Oberkassel is what seems to be the remains of the oldest known domesticated dog, buried there alongside humans at least 14,200 years ago – which means we had pet dogs before the dawn of agriculture.

The page comes from Diluviale Menschenfunde in Obercassel bei Bonn (“Diluvial human finds in Obercassel, near Bonn”), a 1919 book by M. Verworn, R. Bonnet, and G. Steinmann.
