🔎 UNIDENTIFIED Is this Chert?

[relicdigger3]

Hey guys, I’ve been trying to learn different rock types because I believe it’ll help me identify Native American artifacts out in the field. Is this a piece of chert? It looks like some examples I’ve seen online. It is really hard and I can’t scratch it with a steel nail.

Not chert, it would have concoidal fractures.
wow, that was a battle with the spell checker!
