I found this in the dirt today. All one piece of whatever it is. Mostly greyish translucent with very oriented lines of brown in the corner section that makes it glow orange in the sunlight. The edge looks like it breaks like flint or obsidian. But the larger surfaces are like very smooth bark on a tree branch. Any ideas what it is?
Hmm, yes. I was going to call it the see-throughyness and fancy lines.
