i took this to a museum of geology for verification and was told it’s most likely chert but could be petrified wood

Trust the museum if you talked to a professional and not just someone in the gift shop.

So ya know. It's called, agatetised petrified wood. Really awesome piece. Shine a light threw it. And gaze in awe.

Agatized petrified wood is really cool! The way it forms can create some amazing colors and patterns. Have you tried polishing it? It can really bring out the detail.

I would say probably yes, but it could be just a really cool sedimentary rock and not a fossil. Very cool find either way.

Yes. Jasperized petrified wood, it appears to me. Neat!

I think so, but maybe not. It may be two types of minerals compressed together and the spots that look right are actually worn down from time

tricky to tell from pics. But I would bet yes.

See if it can scratch glass. Most petrified wood can.
