In southern New England, true miniature fluted points have been found, of both the Bull Brook variety, and the Barnes( aka Neponset) variety. At the Templeton site in western Ct., an intact Barnes fluted point only 3/4" long was recovered.
Most New England fluted points were made of exotic lithics from distant sources, often Hudson Valley cherts, or cherts from northern New England, but there were exceptions. The Sugarloaf site near Deerfield, Ma. produced nice rhyolite Bull Brook fluted points, along with those made from NY Normanskill chert. The base of a quartz crystal fluted point was recovered from the Sands of the Blackstone site, near the RI border. Years ago, my wife and I found a miniature fluted point, made of quartzite, and probably of the Bull Brook variety, on Narragansett Bay.
Miniature fluted points may be more common then folks realize, at least here in New England. And fluted technology seemed to persist longer here, perhaps because caribou migration persisted later here....
