Looks like a coprolite to me Gidget! Did it break easily as in crumble or break easily as in fracturing along a set line? Peat if it crumbled, sure looks like obsidian if it fractured.

It looks like a chunk of coal.

Is it peat that comes off your hands and feet? Kate is always dirty after playing on the exposed parts.

Mystery continues..... Clean break - no crumble - didn't get hands dirty. Def not coal. I need to go to geology link.

Thanks detectives of SoWal

It could be a chunk of Ilmenite that has not been broken down which is the black sand that you see mixed in the white in layers...

Very likely could be that - I wish the photo showed the inside though.

I just emailed the geologist. Hoping to hear soon and will let you all know what the answer is.

Thanks again

I am not a geologist but it looks obsidian to me.
