I'll try to cut it in half this weekend and then get it into my saw. I'll post pictures when I do. I'm not expecting much, I'm just interested to see what it looks like inside.

I cut the rock yesterday. I cut around the perimeter with an angle grinder, then hit it with a hammer and chisel. It was softer than I thought when I cut it with the grinder. The slabs look pretty cool, but they're full of little pits.

I can not begin to tell you how awesome I think this is! I am sure it is the same stuff as the fossil I posted a couple days after you posted this one. Funny to think there may be many of them in this area, it is supposedly quite rare for fossils to turn to quartz stuff like these have... and that they are the same "thing"... well that just makes me flip. I wonder if there is a university somewhere that would get excited about this? It would be almost too much to think we have the only ones in the area... so if there is a forest of them, wouldn't it be of some scientific importance to some paleobotanist somewhere? Don't cut up all of that stone Rob! Yes, I am super excited about this!!!!! !!! : )

I think the bubbles are from the 'stigmata', or the pierced areas of the stone. When the root/rhizome was alive there would have been small hair roots growing out of the huge rhizome... think of an iris or a carrot. leaves and stems on one end, fleshy tuber, fine thin roots coming out of indentations in the tuber.

I was able to see the slabs that Rob cut in person and they look like something fossilized to me. He has several segments of the slab that look like they contain a brachiopod with the internal structure perfectly fossilized. I did find a very similar rock when I was up there as well. The pic below is not very good but it has very similar pitting. I am think that the coloration is the result of organic matter (e.g., algea) that was fossilized in limestone or dolomite. The rock is on the right. The left is what I think is banded chert and the bottom is drift wood. My daughter wants there made into drawer pulls.
