Porous Rock

A friend had this rock that looked like a fossil of some sort. My guess was it is limestone because it was not heavy and chipped easily. To me it resembled a tree trunk but other than that I had never seen anything like it and it was a new one to me. 

Found in northern Belize

 Sorry I do not have a name for this rock. Its gorgeous and set in limestone, is all I know!

More identical unexplained rocks

 I showed you the one on the right before, wondering how is was formed. Well, I still wonder. Maybe even more so, as
I found a similar one.

 the one on the left has very similar marks, only finer.

 I see that I have a few followers by now. (thank you guys!) Is there anyone out there that knows more about these rocks than I do? I hope one day someone will venture forth and tell me what they think, or know!

brother rocks

Sometimes we find a unique rock, as the case was with the following rock, found by my son who only picks up rocks of great value to me!

It is clearly a layered rock of some sort. It has a flat surface.

 Then recently I found its brother...

  

Unusual rock

 This is a rock I spotted in our favorite rock hunting area, but I cannot explain it. If the lines were all going the same direction I would be tempted to say petrified, but now it has me stumped. it seems like it would be some sort of fossil, but for now it will just remain one of my unidentified rocks.

Found in Pine Ridge, Cayo District

Pink Rocks

Lately I've had my eye open for these pinkish rocks. I wish I knew what to call them. Just plain old quartz?... Help me out if you can!
