Found this piece in a box labeled 'Dino Bone Utah', most of the pieces in the box are clearly chunks of bone. This one kinda looks like claws? Thoughts?...Just a formation?... Pictured wet:

No help on the ID, but that is freaking cool! I can't wait to see what the input is on this one!

I don’t know. I’d go with Dino claws, too.

Looks like a gas pocket nodule. Rocks like basalt and andesite often have odd shaped voids where hot gas formed pockets during formation of the stone. Later, silica from silica laden ash that overlays those deposits percolates down into the pockets forming agate nodules that can later weather out. The plume agate beds around Marfa and Woodward rch etc are full of those nodules. At Woodward there were a couple of canyons where you could see half nodules still in the host rock. The Mexican agate nodules from Chihuahua form in a similar manner in voids in andesite. Most nodules are kind of almond shaped ( called amygdaloidal) but since the pockets have many odd shapes so do the nodules formed within.

Thanks all for the info! If it isn't dino related then I have no issue feeding it to my tumblers. Once the temps. improve and I have access to running water again I will send it through 220 AOx in my UV45 for a while and see what it looks like after I take some of the weathering off and smooth it out a bit.
