Is this something?

I found this today. It is worked all around. My pictures are not the best but I hope you can get a feel for it.

It appears to be a large core that probably saw secondary use as a chopper.

I'd say probably, but I don't know what. It's not uncommon to find pieces that like that show working and either weren't finished or are but just aren't that refined a tool.

Id say with all the hinge fractures that they started flaking it and realized that it was not going to make the grade!!

Looks like a blank to me, roughly worked into a biface. The material looks like the majority of stuff you find.

I like finding those giant rocks worked all the way around. I bet many were used as is and then worked down and constantly re sharpened ground and reshaped and maybe split off into numerous other tools. Just my guess Cool find.
