Black Rock

I can't believe I forgot to post my photo yesterday! Rest assured that this was in fact taken yesterday!! Anyway, Ruth had this rock on her desk yesterday with a sticky note saying "What is this?" No one knew what it was. I thought it looked kind of like obsidian but apparently it isn't. Ruth thinks it is a chunk of coal. What do you think?

  1. Perhaps it's a fossilized turd.

  2. LOL. Apparently it is anthracite coal. So more like rotten and compressed dead plants from millions of years ago. Is it plants or animals that make coal? I can't remember.
