what do you see it being used for? ancient tools have modern counterparts....hammers, knives, pestles, awls, celts, chisels, etc....what is the function of the thing you found?...that is a good way to start.
It fits so good in ones hand maybe a tool for striking flint. Or put it threw a stick and it could very well be a club. The point is fairly predominant witch leads me to believe it was made that way.
I'm guessing if it was used as a hammer or axe or tomahawk or whatever it would probably have the grooves carved into it to support mounting the shaft to the head.
While it's not impossible that that was a hand tool or some mortar and pestle type of an object, realistically without any markings on it to indicate where and who it came from it has no value. It's more likely just a random chunk of rock that chipped off of another rock in that shape and then was tumbled by the river.
HOWEVER
Given it's similar characteristics to other ancient stone tools, we might be able to put an argument that had a stone age individual found the rock that you're holding, they might have used it to make a tool. They probably looked for rocks with similar characteristics as a starting point for making stone tools in the past. But that's just a hypothesis.
Thanks goldfleks, appreciate your time and like your hypothesis. And I noticed there was a weird groove the rock I've found. I'll give you close ups on it , couldn't care less on value I love to find and collect things [emoji4]
Your next step would be to probably research the history of your area and what types of humans lived there. If you're in an area known for stone age human settlements the chances of that being a stone tool increase
Also just FYI... Kinda ironic as I just watched a Netflix documentary on early humans last night. The current active working theory on the human ancestors that settled North America is based around the Clovis people.
If you do a search of Clovis tools, they all come up looking like this:
Again, not that what you're holding isn't a possible stone tool. But it's probably not a weapon as the Clovis people were already using edged tools by the time they came to the Americas. And they are considered the orignal settlers of North/South America if I understand the documentary correctly.
The problem with stoneage tools that don't have obvious indications of human interaction is that how do you tell them apart from a rock. The answer? You can't. I'm sure plenty of rocks have been used by ancient and modern people to hammer something into the ground for instance. So technically, every rock you find, "could" have been a stone tool.
i think you may have a club.they used them to knock heads,animals they shot with their points,or enemies.i have one like yours i will show ya but others would probally call it a rock.look at the indentations on them about the same are they not,i think they did it to haft it
