Some Kind of Translucent Mineral (lemmy.today)

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?

I've found a ton of petrified wood during my life and never seen any that was mineralized like this. Not to say that isn't possible. It would be really cool if this is a agate that formed in a spot left by a piece of bark or something. The unbroken surface does look like wood or bark.
