A 31,000-year-old skeleton found in a remote area in Indonesia is rewriting what we know about early medicine medical procedures according to a new study published in the weekly scientific Nature journal on Wednesday.
...
The oldest previous known example of a limb amputation had been a roughly 7,000-year-old skeleton from France, whose left forearm had been surgically removed and then had partially healed. This had led researchers to believe that operations of this nature took place in established agricultural societies.
The latest discovery turns that notion on its head and suggests that Stone Age hunter-gathers had a far more sophisticated understanding of anatomy and wound treatment than previously thought.
The skeleton was initially uncovered in 2020 in the Liang Tebo cave which is known for its ancient examples of rock art, going back 40,000 years.
When the skeleton was discovered it was found to be missing the lower part of the left leg, along with the left foot. Upon further examination it was found that the bones were not just missing, they had been removed. The remaining part of the left leg showed a clean cut that showed regrowth and had no evidence of trauma like crushing or splintering.
"It's very neat and oblique, you can actually see the surface and shape of the incision through the bone," Maloney told a press briefing.

The human mind is marvelous.
How do they know it was 31,000 years old. It may have been 32,000 years old.
or 31,573 years old..
Dating
Immediately above the sediment of the distinct grave cut in SU7, a charcoal sample returned an accelerator mass spectrometry (AMS) radiocarbon (14C) age of 31,133 to 30,437 calibrated radiocarbon years before present (cal. BP) with a 95.4% probability (D-AMS38332), providing a stratigraphic minimum date for the inhumation of TB1 (Supplementary Table 2). In addition, a charcoal sample within the burial feature, collected from the pelvic girdle, returned an estimate of 31,110 to 30,437 cal. BP (D-AMS38337). Charcoal recovered from SU9, the stratum underlying the burial feature, provides a stratigraphic maximum date, with an estimate of 31,519 to 31,054 cal. BP (D-AMS38338). The SU9 sample was situated immediately underneath the burial cut, although within a completely distinct stratum that clearly underlies both the burial feature and the equally distinct sediments of SU8. Thus, associated radiocarbon dating of the charcoal samples indicates an age estimate for the TB1 burial feature of between 31,519 and 30,437 cal. BP, with a mean of 30,978 cal. BP. Bayesian chronology suggests that the boundary between SU7, which caps the burial, and the burial feature itself, is 30,853 ± 770 cal. BP; and the boundary between the burial and the underlying SU8 is 31,135 ± 864 cal. BP (Extended Data Fig. 10 and Supplementary Table 3). Furthermore, radiocarbon dating from overlying stratigraphic units confirms subsequent human occupation at the site transitioning the Last Glacial Maximum and the Holocene towards the surface (Supplementary Table 2), with the depth measurement of each sample showing strong and significant correlation with the mean calibrated age (r = 0.990, r 2 = 0.981, F = 253.942, p = 0.001). The positive age–depth relationship of these samples (completely lacking inversion) supports an argument for minimal deposit reworking and diminishes the possibility of introduced charcoals entering lower units, including burial-fill sediments.
In addition to radiocarbon dating of the charcoal, a combined uranium-series and electron spin resonance dating technique was undertaken on a sample of TB1’s left mandibular molar (M3) and this analysis returned an age estimate of 25.4 ± 4.3 thousand years old (1σ), which is within the error of the 14C burial-context age. Both the uranium-series analysis in isolation and radiocarbon dating of the skeletal remains were unsuccessful owing to insufficient amounts of uranium and collagen in the sample, respectively. Incorporating the electron spin resonance age into the Bayesian model gives a modelled date of 31,201 to 30,714 years ago (2σ or 95.4% probability) for the burial (Extended Data Fig. 10). In summary, we infer a secure Late Pleistocene age of between 31,000 and 30,000 years for TB1, making this, to our knowledge, the oldest intentional primary burial of a modern human currently known from Island Southeast Asia.

Gotta wonder how anyone could know for sure it was a “surgical” amputation and not a huge critter with razor sharp teeth amputation. Ahh...science! Can’t tell the difference between a man and a woman but know for certain that an ancient lost limb was surgically removed. What will they tell us next?
Maybe they will tell us Joe Biden won the election, or that we need another Covid booster shot.
They wuz hungry. They done chopped offn his leg n ate it.

... or 32,767 years old.
Maybe somebody else became angry with him, and wanted make sure his bad habits ceased.
Did he not offer Frankenfuhrer
An offering, biden aka Frankenfuhrer licked his finger and his arm rotted off?
Just sayin..
Samurai wound.
Clean cut....
Maybe Iza or Ayla did it?
Or, he could just be a victim of an alligator.
