Regarding that beautiful exotic find of Ernie R. at Randy's dig site and now graces the front page a "the find of the week"
I believe that some "exotics" started off life as a common "something" then someone altered it for their own purpose like a practice piece, special funeral gift, ornamental gift etc etc.
The general shape and size has a hint of BIG SANDY...Then as I'm a big believer that some points could be from distant places as per the scholars [
I have one item from Williamson TX that I dug myself so I know it's real, that is listed in the books from the KENTUCKY vicinity ]
The examples of Big Sandy in the SOUTH CENTRAL section of the overton's including Texas is HORRIBLE !
So I looked in other sections....Gulf coast [GC] North central [NC]...East central.......BINGO
Start page 350...take your choice...The overall outline and the side notches are a PERFECT match. There are 4 pages of Big Sandy examples.
That unique basal notch makes it exotic...in Texas, but on page 351 and 352 there are a couple of types that where base notched is their standard design.
East central area is shown in the book as being as close as MISSISSIPPI extending up to the U/P of MICHIGAN.
Maybe someone from Detroit was vacationing In Texas and Stayed at the Randy KOA !
You are most definitly right about the Overprice Book being Horrible and sadly lacking with some type examples, and the pricing guide is nothing short of a Fantasy. I guess they are calling the point an exotic form......since they don't know WHAT to call it! Your Big Sandy variation certainly seems viable, but there are also appear to be 3 variations with Frio points as well, one of which matches close enough for scrutiny. Most of us know what the Buck Tooth form of Montell looks like, but the Big Foot form of Frio is not that common, is certainly larger, and seems to occur more in the South part of the hill country than the North. Being relavant to the middle/late archaic, maybe the flintsmiths of the culture had Buck Teeth and Big Feet, and were referred to as the....exotic ones!
