Perhaps someone can help me out here, Naia was a maybe 100lb undernourished teenage mother who fell into a sinkhole in the Yucatán maybe 13,000 years ago.
https://hoyonegro.ucsd.edu/naia.phpThe relevance here is that I have read somewhere that early populations from South/Central America had an unusual degree of sexual dimorphism wherein the guys averaged considerably larger, and that more than a few males exhibited healed skull fractures, indicating they hit each other a lot.
If I’m recalling all that correctly, this Minnesota skull cap’s healed fracture would fit.
Can’t find a source of where I read it tho.
