It s not clear what beast produced the sample (technically known as a coprolite) but it s expected that it will fetch between $8,000 and $10,000 when it goes under the hammer.
The clay-coloured sample is thought to date back to the Oligocence and Minocene Epochs, making it between 5.3 and 33.9 million years old.
“This truly spectacular specimen is possibly the longest example of coprolite - fossilised dinosaur feces - ever to be offered at auction,” reads the auction description from I.M. Chait. “It boasts a wonderfully even, pale brown-yellow colouring and terrifically detailed texture to the heavily botryoidal surface across the whole of its immense length.”
For those of you who have never had to describe fossilized, possibly-dinosaur poo, botryoidal means globular and comes from the Gree
Despite their innate weirdness, coprolites and paleofeces (fossilized human faeces) are rich sources of information for archaeologists and were also invaluable at the time of their creation: dinosaur droppings provided the fertilizer necessary to keep those prehistoric jungles looking green and lush.
Coprolites have been used for everything from dating the timeline of certain species to proving the existence of cannibalism in ancient human cultures (thanks to the discovery of human proteins in unearthed paleofeces).
