I was out rockhounding today and found this very unusual piece of pet. wood -- I'm going to call it zebra petrified wood, for lack of a better term. Has anyone ever come across something like this before, or know what causes the banding (which runs across the grain of the wood ie perpendicular to it)? I've never found anything like this before... I guess that's what makes rockhounding so fun!  |

Nice chunk of wood!!!!
I have no clue about the banding. But if I were to guess, I'd say maybe it's bark? would explain banding going accross the grain.

All I know is that's one incredible piece of pet wood. If you find more, let me know. I'd pay a pretty penny for some of that. Wowser!

That looks an awful lot like Tiger Eye. It is wet, so it is hard to tell. I would love to see a cut piece.

That is a nice piece of rock, the black looks like burn marks.

Looks very similar to the natural banding found on "flame maple" that's used on instruments...   Jimmy |

Thanks for all the comments and ideas. The top side of the wood is stained dark on about 2/3 of its face, so I only showed its good side here. The staining looks to be very superficial, so I think it should come off easily. The banding is present on the flip side too, and a side view (not shown), makes it clear that the banding runs right through the wood. I might have gone with the worm hole or bark ideas, but since the pattern is also on the other side, I think that rules out bark. And although the rock is only about an inch thick, the banding runs right through the piece, and I can't imagine a worm that could make that kind of bore hole. Beeper's natural banding idea might be a possibility, but I don't see how the colouring would be maintained when the rock was silicified? So I think I'm still mystified. Notice how many of the bands seem to split into two near the top and bottom of the pic, in a kind of a U-shaped pattern... that must be a clue, but I don't know what it's telling me. This kind of petwood is ranges from 60-90 million years old if that helps at all. I don't know what kind of species of tree it was. Maybe they are dinosaur gnaw marks? |

I still say grill marks, maybe some kind of caveman decided to try grilled tree - this may be the first instance of the allmighty grill!

Grilled tree... hmm, could be an important fossil to show the first (failed) efforts of humans to use fire for cooking... guess I should contact a museum about this  |

It could be tiger maple as in the wood used for the violin. As the minerals seeped into the wood perhaps some of the minerals got stuck in the areas which cause the stripe effect in maple. There is such a thing as zebra wood, but the different colors run with the grain.
However it happened, it is a cool looking piece of wood.

Only one problem - Tiger Maple is a modern wood- Pet wood is 100's of Millions of years old!
