Is this a fossilised sponge?
« on: 21/12/2015 20:50:05 »
I found this in Belton, TX.  It might be a pound...very light.  It is solid but has tons of holes...almost like a volcanic rock but something about it makes me think this is something else.

I'm very new to this but my wife and I have taken up a new hobby of searching for Indian arrow heads.  I also find other neat specimens such as this.

Sorry if the pic is a bit fuzzy.  I'm having issues resizing them.

Thanks for any help you may provide,

G. J. From TX

Some of the holes in your find look rectangular,  so not [gas] bubbles in volcanic rock.

"Tabulate coral" can have rectangular-features , see ... https://www.google.com/search?q=Tabulata

I'm hating the pic I uploaded.  I have an app that will resize my pics but to resize it to a small enough size made the pic blurry. 

The holes are actually mostly all round.  However after some research I'm wondering if it isn't a piece of oolitic limestone.  It was found in an area with mostly shell and limestone rocks.

Thank you for your feedback.
