Nice finds, that is a very nice blade. I always like the petrified wood. To bad that variety doesn't lend itself to the fine flaking as some of the others.
I agree Quito, but I recently came across a site where A LOT of palm wood was used. After one day I have only found flakes and pottery but I expect some great finds are to come!
Ok gonna take a leap here...this piece of palm wood appears to have a place where a point was roughly shaped then flaked off!! Could be just a coincidence...
