Can anyone identify this. I believe it's fossil coral???(https://uploads.tapatalk-cdn.com/20241031/59761c12c7a4528e163cb49377c5a4bd.jpg)

It looks like a chert nodule like the snakeskin chert nodules from Oregon. Identically shaped nodules with less surface pattern are very common near Frenchman's coulee in central washington.

It has a bone smell when grinding. Like the smell of a tooth, or bone.

There's a lot of sponge chert in TX.

The symmetrical shape makes me wonder if it could be a vertebra.

Sorry life's been crazy and I've been ignoring my stones. I have to laugh on this one with the guesses. Here is mine. It is a sedimentary formation like a veil type of stalactite. You can see in the upper left section and lower right where it was forming concentric rings in the slow deposit of material. Smell can be a number of things included in the host even sulfurs etc. Not a bone, not a coral. I can upload pics of cross sections of veil stalactites for you just not at my finger tips right now.

Thank you!

I agree with Steve on both points. After another, more careful look at the picture I find my previous guess (vertebra) ridiculous.
