Meat-Shaped Stone
Sadly, this story isn’t all it’s cracked up to be. Some quick googling will show you that most geologists don’t think this is a real steak-like rock. Instead, they believe someone painted it on, as the coloring is unnatural. You’re not going to find something as strangely colored as this underground.

Additionally, looking at the edges of the reddish parts, they look rather smudged and almost like brush strokes. The colors would be bolder and clearer if this were a real mineral. It’s a great practical joke, but unfortunately, this spooky picture is fake. It’s a good attempt but they could’ve done better.
