Found near Menard, Texas.
Not an end scraper (which you find from Clovis to contact, not special to Clovis), just a large flint flake.
That upper edge of an end scraper has lots of flakes taken off, has a specific angle and is quite rounded. Historic usage of them was for scraping hides w/o tearing. Your flake would just tear through the hide because of all the sharp edges on the scraping edge.
