What could this be?

[GoExplore]

Found this item while surface hunting a native hunting camp in southern Nevada where I have found several points. Appears to be shaped, but I’m still scratching my head as to what it can be. Maybe not even an artifact?

Maybe a turtle back scraper

Also possibly a preform. It's nice material.

looks worked by a frustrated flint knapper and then tossed to the ground. Lots of steps in the rock and still has lots of cortex.

Agree with Smokey--looks to be a preform.

Maybe it served its purpose well enough the owner was satisfied and used until it was lost to the ages. Then you picked it up.

WAY too thick to be a preform. Ad hoc tool &/or flake core, IMHO.
