Concrete Arrowhead?

[Shane1234]

Hello everyone I had a freind that found this arrowhead in Oklahoma. Is it concrete or something else. I need help with identifying the material.

Cool find! It’s definitely not concrete. It’s a type of chert or flint. It looks like a woodland period Gary point.

I'd say either a low grade chert or a quartzite type.

Nice, some of the folks around here just call it a conglomerate chert...

[antmike915]

That does look like concrete, I would say a conglomerate material as well. Pretty cool piece.

Definitely not concrete... The Native Americans weren't around for the white mans invention of concrete. That would be a very low grade stone, possibly limestone or something similar.

Just for a bit of fun try researching concrete. I was looking into early Romans a few months back and found out quite few things that were incredible. As a teaser ask yourself when dya think concrete was invented? I was out by quite a few years!

To tell you the truth, I'm not sure when concrete was invented, I just know the American Indians never had any, at least not the stuff we think of today.

Even if they had concrete they didn't have re-bar so no buildings.
