It may look like a geologic find, but a three-pound red and white fossil heading for auction today is actually a pile of dinosaur dung.

Bonhams New York is putting the prehistoric deposit up for sale along with a 30,000-year-old woolly mammoth tusk, expected to sell for up to $50,000.

The auction house predicts the 50,000-year-old skull and jaws of a giant beaver will sell for about $20,000.

The dinosaur dung looks like a rock on the outside and a colorful mineral inside.

It is 130 million years old and is expected to sell for between $350 and $450. It has lost any original odor.
