Help indentifying rock specimen?
I obtained this rock from a landscaper in North Texas some years ago and would like to know what it is and where it comes from.
It's about 14" long, very dense, no visible grain, smooth (almost slippery) to the touch, light tan or bone colored, and is entire - that is, it's not a piece broken off of something larger. It is heavily pocketed as though there were inclusions that have been dissolved or eroded away.
I hope this link will get you to a photo. First time I've used photobucket. If that doesn't work, I can email it to you.

This is my second attempt here but first try with a photo. Thanks to those who answered the last time.

looks like a fossil of a bone at first glance. I see potential clasts, so it could be a form of limestone. Try putting a tad bit of lemon juice on it. If it dissolves a bit, then youve got limestone. Im also guessing it could be a vesicular volcanic rock, which cooled quickly, due to the fact that there are no visible grains. I honestly cannot name the rock. If its igneous, its certainly quite felsic.

I agree with the first answer. It looks to me like a piece of limestone that has undergone solution weathering.
