Amazonian or Papua New Guinea Spears

Thanks to all for the insightful comments!The lance measures 84" tall and the blade is heavy enough to also act as a club.
The insect infestation could have been original to the tree prior to it becoming a spear, however the damage is all on one side, as so many of these weapons are prone to be;probably where they leaned against a wall in a garage or barn.
