The longest piece of fossilised dung ever found - which measures 40 inches in length - is expected to fetch up to USD 10,000 at an auction in California.
The fossil believed to be the longest known specimen of ancient excrement could be up to 33 million years old, according to a gallery in Beverly Hills, which is auctioning off the specimen next week.
The coprolite is expected to fetch between USD 8,000 and USD 10,000, 'Live Science' reported.
According to the auctioneers, the coprolite has "a wonderfully even, pale brown-yellow colouring and terrifically detailed texture to the heavily botryoidal surface across the whole of its immense length."
A "botryoidal" surface is one with a lumpy texture.
The seller found and dug up the fossilised feces in 2012, on private land in Toledo, Washington, said Jake Chait, natural history director of IM Chait Gallery.
Chait and his colleagues said they don't know what kind of creature left the load, which has been separated into four pieces and mounted on black marble.
This is not the first time ancient poop has gone under the hammer.
In 2008, Bonhams New York sold a 130-million-year old pile of dinosaur dung for nearly USD 1,000. Chait said he's sold much smaller coprolites for around USD 6,000.
