Is it petrified wood or chert?

[Tucker2]

Hello! I've been rockhounding in Oregon but don't know what I have. I've been told it's either chert or petrified wood. I'm looking to be educated. Thanks for your time!

yes pet wood, but both are cryptocrystalline silicates (CCS).

Hey thank you very much for letting me know these are CCS. I am learning.
