This is a genuine piece of doo doo that fossilized and was replaced by the mineral Marcasite. Fossilized poo is known as Coprolites. Marcasite which is a type of pyrite, can also be known as Fool's Gold.
Dating to around the Jurassic Era this nugget is believed to have come from a small species of shark that feed on mollusks, crustaceans and fish. As some pieces contain remnants of fossilized shell that the creature was unable to digest.
It is also believed that the poo was left inside an underwater cave or cut out which helped preserve the specimens.
