Expedient tools. Normalcy a luxury, use a priority. No Dino bones in WV, sedimentary rocks are too old. Have found a nice horn coral in the creek but my geologist buddy says it is "geological pollution" most likely transportation from the eastern part of the state with limestone.
I know of a spot that produces those type of tools. Always fun to look and see what I might find. I have found triangles there so probably a woodland site even though the tools look older by the design of them in my area.
