Good guess but because of many other specimens with these features I've been able to put together numerous clues with some detective work and form an accurate hypothesis. On the above specimen you can see the ghost of a wood limb in the middle that's rather large. The growth rings aren't really well defined, but you can see the radial cracks emanating from the center typical of a limb. OK, that's one part of the story. The second part is that white structure. Detailed somewhere in the previous 162 pages of this thread we've been able to determine that anomalies like this are the burrows of dung beetle larvae that are filled with the excrement of the larva. Fossilized poo inside fossilized poo. It's interesting to note that the limb was not totally digested, and the larva deflected around the contour of the limb in its burrowing endeavor. Wait. So millions and millions of years ago an animal eats a branch and it doesn’t fully digest. Out it comes in some poop, which Mr. Dung Beetle comes along to deal with. In his travels through the pile he burrows into that partially digested branch, leaving behind a bunch of his own poop. And in the end it ALL becomes fossilized and wound up with you??? Again, I absolutely love that. It would be crazy to find a fossilized dung beetle in some coprolite some day. I think we found one some time back. Can't remember where tho.

Welcome from Utah. Curious about your name, why 1925? If that's your birthday you are 99 years old. Really?

Get something with a rock clamp to make smooth cuts. I'm 87 and out of the game.

Perhaps a list of the rocks you would like to find?

Beautiful Stuff. Too bad I don't saw or cab anymore. If I did, I'd take all you would give.

Imagine A wall of water 5 or more miles high under a 500 mile diameter Comet racing Southeast across Utah carving and washing away rocks through Monument Valley and down the Grand Canyon.

Thanks for posting! Makes us all think. Silver is my guess. Why is the west so different from the east? Because we were grazed by a comet 100 million years ago! That gave us many unusual minerals. Geologists don't know this because they don't understand comets. Comets do not explode on contact. Think "dirty water Balloon". That built the Rocky mountains as it raced from the Beaufort sea to Mexico and then submerged them under the Western inter mountain Seaway for 40 million years, until the asteroid hit the Yucatan and liberated it Creating the greatest Magic trick of all time.
