T. Rex poo heads to the Smithsonian

The fossilized poop was deposited about 65 million years ago in southwestern Saskatchewan, Canada, and is currently housed in the Royal Saskatchewan Museum. The feces contained bone fragments, possibly from a duck-billed dinosaur or a horned creature such as Triceratops. The shards of bone are still jagged, suggesting they hadn’t been marinating in the T. rex long enough for stomach acid to wear them down.
