A rare hunk of poop from a Tyrannosaurus rex will soon be making its way to the Smithsonian Natural History Museum in Washington, D.C.

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.

The dino poop, also known as a coprolite, will be appearing in the "Putting Dinosaurs in Their Place" exhibit, which opens at the Smithsonian next year, CBC News reported.
