These seven animal bones clearly show human traces, the are carved. They were found in the Santa Fe River in Florida, USA. The age of the bones is about 7.000 years - stone age!
Most of them are so called "bone pins" which were used as a "needle" in a handle made of deer antler or as spearheads used for fishing.
The biggest bone measures about 7 cm in length, all pieces are unbroken.
No manipulations - just as found.
Interesting but affordable!
