I have seen such a stone for the first time. Found it in the forest.

Pretty sure it's a chert nodule. When posting images for identification we remind you that it is helpful to at least include a location where it was found. Read the section, in the index for beginners, for tips on self identification. We've had a lot of rock ID questions that seem like a casual interest in found bits of rock. This site welcomes interested novices, but that interest calls for doing your home work. A quick review of the gallery will reveal that it is heavy with fine minerals, and, that remains our abiding interest. Chert nodule.

Really looks like a piece of flint / chert (sedimentary siliceous rock).
Can check it trying to scratch a bottle glass with it. If glass stays permanent scratched will be as said.
Regards.

Okay. I thought it was a salt lick like my goats use!

Procol, the knowledge here is deep and wide, mine excluded. You did the right thing. Welcome to the forum. Sorry if I seemed pompous. We all started with picking up cool rocks, as you have done,. I collect quartz, your specimen is a form of cryptocrystalline quartz. You can't have a rock collection with one rock. Keep looking. Stay curious and you will be rewarded.

It actually does look like a mineral block my calves lick on too!
But at first glance I would've guessed it was an ancient skull of some sort.
I couldn't have been more off. ;)

| Could be from current. Or organisms. Just guessing.

| The external form does look like massive chert, but the large broken cross-section looks unusual. Where is it from - what's the nearest city ? Can you give us a well lit picture of the large broken surface ? Thanks, Tom
