In addition to a Neolithic monument, the builders of Stonehenge left behind one thing rather less celebratory: fossilized clumps of poop. A brand new evaluation of those so-called coprolites suggests that in epic winter feasts, the ancient employees and their canines ate undercooked meat littered with the eggs of parasitic worms.
The group of researchers uncovered the fossilized “poop balls” in a refuse heap at Durrington Walls — a Neolithic settlement located round 1.7 miles (2.8 kilometers) from Stonehenge. Experts imagine that the location would have been residence to lots of the employees who constructed the enduring rings of standing stones, which could have acted as a photo voltaic calendar, between 4,000 and 5,000 years in the past, based on an announcement by the researchers.
Researchers analyzed 19 coprolites discovered on the web site, originating from each people and canines, and so they discovered that 5 of the samples (4 from canines and one from a human) contained the eggs of assorted parasitic worms. The group thinks {that a} majority of the parasite eggs were served to the Neolithic builders in undercooked meat dishes loved at massive winter feasts, the leftovers of which were possible fed to the canines. This is the oldest proof of parasitic worms within the U.Ok. that may also be traced again to their authentic supply, based on the assertion.
“This is the first time intestinal parasites have been recovered from Neolithic Britain, and to find them in the environment of Stonehenge is really something,” examine lead researcher Piers Mitchell, a organic anthropologist on the University of Cambridge within the U.Ok., mentioned within the assertion.

Four of the 5 contaminated samples, together with the human excrement, contained lemon-shaped eggs belonging to unknown species of capillariid worms, a kind of parasitic worm that grows inside the inside organs of a number of animals together with rodents, monkeys and livestock reminiscent of cows, sheep and pigs.
Capillariid worms have an uncommon life cycle that includes at the very least two different animals. First, the worms infect animals — reminiscent of rats — that unintentionally ingest the eggs from their atmosphere. The eggs then connect to the animal’s inside organs, such because the liver, lungs and intestines. The eggs hatch and because the worms develop, they begin to devour the organs earlier than finally reproducing asexually to supply extra eggs. The contaminated animals are then predated upon by bigger predators and the eggs are handed via the predator’s digestive tract earlier than being excreted again into the atmosphere to be ingested by one other host.
Modern people are identified to be contaminated by two species of capillariid worms: Capillaria hepatica and Capillaria philippinensis. When these worms start to devour an individual’s organs, the illness is known as capillariasis, and it may be deadly if not handled correctly, based on the Centers for Disease Control and Prevention.
However, on this case, the Stonehenge builders and their canines were possible not contaminated by the worms. If that they had been contaminated, the eggs wouldn’t have made it into their stool as a result of they might have settled of their inside organs and hatched. Instead, they possible ate meat from an contaminated animal and handed on the eggs very similar to a predator would within the wild, based on the assertion.
“The type of parasites we found are compatible with previous evidence for winter feasting on animals during the building of Stonehenge,” Mitchell mentioned. Feasts were extra frequent in winter as a result of that was when a majority of employees traveled to Stonehenge: During the remainder of the yr, they returned residence elsewhere within the U.Ok. and constructing work slowed down, based on the assertion.
The builders possible acquired the eggs after consuming offal, the intestines and different inside organs, from cattle, the researchers suspect. Previous research have proven that builders could have herded cattle greater than 62 miles (100 km) to be consumed at these feasts, and capillarid eggs can infect cattle and different ruminants, based on the assertion.
Offal isn’t eaten extensively at the moment (though it’s nonetheless frequent amongst some Asian cultures), however was a well-liked meals amongst Neolithic communities, based on the assertion.
This explicit offal could have been undercooked. “Pork and beef were spit-roasted or boiled in clay pots, but it looks as if the offal wasn’t always so well cooked,” examine co-author Mike Parker Pearson, an archaeologist at University College London within the U.Ok., mentioned within the assertion.
In 2021, one other examine from the Durrington Walls web site revealed that the ancient builders additionally ate ‘power bars’ produced from berries, fruit and meat.
The ultimate canine coprolite contained eggs of a tapeworm, probably Dibothriocephalus dendriticus, which is generally present in freshwater fish. Since there is no such thing as a proof that fish was consumed on the Durrington Walls feasts, the researchers suspect that this canine possible ate an contaminated fish earlier than the builders traveled to Stonehenge for the winter.
The examine was printed on-line May 18 within the journal Parasitology.
