This Saturday, a Beverly Hills gallery plans to auction off a piece of crap—literally. The IM Chait Gallery says it will put a 40-inch-long piece of excrement up for auction, and it hopes to fetch around $10,000, LiveScience reports. Why the big bucks? The "eye-watering" poop "boasts a wonderfully even, pale brown-yellow coloring and terrifically detailed texture ... across the whole of its immense length," reads the gallery's description. Oh, and the fossilized dung (or coprolite) could be 33 million years old, according to the auctioneers.
Though it's not known which species excreted it, it's going up for sale alongside five smaller pieces of "petrified feces" found in Washington state and thought to be from Miocene turtles, a spokesperson tells the Daily Mail. Paleontologists might buy the poop to examine it for more data, like information on diet, but collectors like buying the stuff too, Boston.com reports. A 130-million-year-old pile of dinosaur poop sold for almost $1,000 in New York in 2008, and Chait has sold a few smaller coprolites before for around $6,000 each. So what makes this one so special? "I've never seen anything close to this in terms of size," the gallery's natural history director says. It's even been mounted on black marble and displayed in four pieces so it won't break during shipping. (Last month, a Neanderthal latrine yielded the oldest human poop ever discovered.)
