The subject of Starr and Zapata counties got me to thinking about some material I used to find there that looked like alibates or tecoves. Has anyone found or have a comment about this stuff? "Stuff" is a highly technical term that I use.
Never found anything like alibates when hunting there, did find a lot of agate and some agatized wood. Also, some of the points that I found there were of the same flint that is common in points found in Mexico. A lot of carryover of material. The Mexico flint is of a drab black or black and white type.
