Very unique, lotta workmanship in that piece of jewelry / adornment. What would the Nueces people have traded for that seafood ? translucent flint, Mammoth ivory ??
Any chance of a better look other than a picture of a picture on a cell phn ?
Is there enough curve in the shell to hear the ocean ?
Since we have nothing but a cell phn pic with no scale of this item, I was surprised to hear from a digger that was there that day that it is H U G E
( not your average 2 - 3 inch "gorget " )
Maybe too big to wear ? maybe the holes were for attaching something decorative and used as a ceremonial piece ?
