Yet another stone fan. Welcome to the club!
Spruce or fir tree print sounds fine to me... Not gonna argue with the plant experts 😉

Would love to see a photo of that petrified wood you found. I wonder how different it looks from the ones we have... And if you've figured out what kind of tree it is by looking at its bark. I know I can't but im sure you 2 would easily find the answer.

Thanks again for your kind words of support😘
