Is it agatized Indonesian fossilized coral? Oh wait… that was for What’s that #22… never mind…
Bingo dendowling, a new winner! You are exactly right. How did you know (have you seen something like it before?)
It is quite large. 4" across, and was polished in 1940.
You can see the trabecular structure of the porous bone and marrow, mineralized over eons, with a peculiar affinity for uranium.
Some Jurassic Park aspirants have tried to isolate DNA from Dino bones, but the structure is mostly lost.
Details on this globe: Jurassic, Morrison Formation, Utah. Formerly part of the Zerk Lapidary Collection.
Thanks! Hadn’t seen this before. Just thought it had cool colors and pattern and searched google images. Looked at red stones first – Carnelian, Citrine, Jasper, Jade. But, their marble patterns were either too smooth or too irregular. I also thought the pattern looked like biological tissue – muscle, brain, liver. Then, spongy bone patterns started to look more like your pic. This object looks hard and shiny so, searched petrified bone and found gembones and agatized bone.
BTW, Flickr has a lot of good pics of dinosaur gembones. [http://www.flickr.com/groups/gembone_lovers/pool/]
Just saw this gorgeous 32x microscopy zoom of dino bone in the January 2014 SciAm:
"The red bubbles Douglas Moore documented in the process may look like blood, but they are in fact iron oxides mixed with a crystalline form of silica known as agate—the same stuff that often makes geodes and petrified wood so colorful. Through a chemical process that has mystified geologists for centuries, silica reacted with bone to “agatize” the entire specimen."
