Found this last fall. Not particularly beautiful nor important, but pretty interesting. The area I found it in has a fair number of geodes and lots of banded nodules, many of which are broken. This one is virtually intact and has very thin walls. In one of the photos of the hole you can sorta see the bubbly interior side of of the wall. Can't do much with it other than put on a windowsill, and occasionally pick it up, saying, "Hey that's kinda cool." flic.kr/s/aHskA4b1CV |

Very cool. Is it mostly hollow?

Well, I never saw one like that before. Very cool. I'd keep it around.  |

Weird little dude. Fossilized coral?

Very cool. Is it mostly hollow? Entirely. This what was so amazing to me. Walls, as near as I can tell, are pretty uniform at 2-3mm thick. |

Weird little dude. Fossilized coral? I'm no expert, but I don't think so. Doesn't seem to be much in the way of marine stuff where I found it. Just lots of agate nodules and broken agate geodes that look to me to have formed in the usual way, perhaps a void that then fills with mineral-rich water, which deposits overy time? |

The surface pocked with almost perfectly round features is extremely common in the area where I found it. I have quite a few grape- to tangerine-sized nodules with surfaces like that. Unfortunately, the interiors of most of them are pretty boring. Some have really nice concentric banding, but very low contrast. A very few have a thin, uniform green coating which when tumbled just the right amount (so that the coating remains in those pocks) gives a clear, green polka-dotted agate. |
