The artifacts that myself and renegade50 no longer post pics of are late paleo to middle archaic to late-archaic periods. All darts, blade, atl-atl points. 3500bc- to 9000BC.
But some of the Big Sandy side-notch points and smaller Kirks c.n. are in the 'small' to 1" range. Those were slung not with a bow. They were used on eastern buffalo, elk, possibly ground sloth, deer, and other Halocene fauna. Mega-fauna were practically zero'd out by tail end of the post glacial p.
It's believed the bow wasnt adapted/discovered/adopted till about 800 AD.
My thoughts are that outside of ceremonial pieces from the Mississippian Era peoples, everyday flint fare from that period is simply ho-hum at best.
