A man in Texas claimed he shot an armadillo on a highway at 3AM and the bullet ricocheted off the animal and hit him. He was treated at a hospital and released.
He obviously had seen THIS story that states a man in Georgia used a 9 mm pistol to kill an armadillo, but the bullet also ricocheted off, hit a fence, went through the back door of his mother-in-law’s mobile home, through a recliner she was sitting in, and into her back.
It sounds more like an excuse he’s using to possibly cover up a shooting accident.
To get to the bottom of it, a test with a dead armadillo, of course, would be helpful, because it’s not making sense. Armadillos don’t have “armor”, their outer covering is a combination of bone and a tough tissue coating. Its carapace or “shell” is made up of scutes composed of the protein keratin. It’s tough and extremely useful but not bullet proof just like bone is not bullet proof. Are Mythbusters still accepting suggestions?
While one incident might be a fluke, these miracle armor-dillo stories sound like the birth of an urban legend, which is probably bad for the armadillo.
