Just edited to add two paper citations for the phytoliths and microwear studies. Have fun! It’s a deep rabbit hole largely ignored by popsci publications so there’s lots to explore.

As you seem knowledgeable of this topic and it is super interesting, any books you would recommend that gives a good broad overview of all of this?

Thanks! I'll add them to my reading list for today. Its going to be interesting, I can already tell.
