A brand new evaluation of historic faeces discovered on the website of a prehistoric village close to Stonehenge has uncovered proof of the eggs of parasitic worms, suggesting the inhabitants feasted on the inner organs of cattle and fed leftovers to their canine.

Durrington Partitions was a Neolithic settlement located simply 2.8km from Stonehenge, and relationship from round 2500 BC, when a lot of the well-known stone monument was constructed. It’s believed that the location housed the individuals who constructed Stonehenge.   

A staff of archaeologists led by the College of Cambridge investigated nineteen items of historic faeces, or ‘coprolite’, discovered at Durrington Partitions and preserved for over 4,500 years. 5 of the coprolites (26%)—one human and 4 canine—have been discovered to comprise the eggs of parasitic worms.

Researchers say it’s the earliest proof for intestinal parasites within the UK the place the host species that produced the faeces has additionally been recognized. The findings are revealed at the moment within the journal Parasitology.  

“That is the primary time intestinal parasites have been recovered from Neolithic Britain, and to search out them within the setting of Stonehenge is absolutely one thing,” mentioned research lead creator Dr. Piers Mitchell from Cambridge’s Division of Archaeology.

“The kind of parasites we discover are suitable with earlier proof for winter feasting on animals in the course of the constructing of Stonehenge,” he mentioned.

4 of the coprolites, together with the human one, contained the eggs of capillariid worms, recognized partly by their lemon form.

Whereas the numerous kinds of capillariid around the globe infect a variety of animals, on the uncommon event {that a} European species infects people the eggs get lodged within the liver and don’t seem in stool.

The proof of capillariid eggs in human faeces signifies that the particular person had eaten the uncooked or undercooked lungs or liver from an already contaminated animal, ensuing within the parasite’s eggs passing straight by means of the physique.

Throughout excavations of the primary ‘midden’—or dung and refuse heap—at Durrington Partitions, archaeologists uncovered pottery and stone instruments together with over 38,000 animal bones. Some 90% of the bones have been from pigs, with lower than 10% from cows. That is additionally the place the partially mineralised faeces used within the research have been discovered.   

“As capillariid worms can infect cattle and different ruminants, plainly cows could have been the almost certainly supply of the parasite eggs,” mentioned Mitchell.

Earlier isotopic analyses of cow enamel from Durrington Partitions counsel that some cattle have been herded nearly 100km from Devon or Wales to the location for large-scale feasting. Patterns of butchery beforehand recognized on cattle bones from the location counsel beef was primarily chopped for stewing, and bone marrow was extracted.

“Discovering the eggs of capillariid worms in each human and canine coprolites signifies that the individuals had been consuming the inner organs of contaminated animals, and in addition fed the leftovers to their canine,” mentioned co-author Evilena Anastasiou, who assisted with the analysis whereas at Cambridge.

To find out whether or not the coprolites excavated from the midden have been from human or animal faeces, they have been analysed for sterols and bile acids on the Nationwide Atmosphere Isotope Facility on the College of Bristol.

One of many coprolites belonging to a canine contained the eggs of fish tapeworm, indicating it had beforehand eaten uncooked freshwater fish to turn out to be contaminated. Nonetheless, no different proof of fish consumption, similar to bones, has been discovered on the website.

“Durrington Partitions was occupied on a largely seasonal foundation, primarily in winter durations. The canine most likely arrived already contaminated with the parasite,” mentioned Dr. Piers Mitchell.

“Isotopic research of cow bones on the website suggests they got here from areas throughout southern Britain, which was probably additionally true of the individuals who lived and labored there.”

The dates for Durrington Partitions match these for stage two of the development of Stonehenge, when the world-famous ‘trilithons’—two huge vertical stones supporting a 3rd horizontal stone—have been erected, almost certainly by the seasonal residents of this close by settlement.    

Whereas Durrington Partitions was a spot of feasting and habitation, as evidenced by the pottery and huge variety of animal bones, Stonehenge itself was not, with little discovered to counsel individuals lived or ate there en masse.

Prof Mike Parker Pearson from UCL’s Institute of Archaeology, who excavated Durrington Partitions between 2005 and 2007, added: “This new proof tells us one thing new in regards to the individuals who got here right here for winter feasts in the course of the development of Stonehenge.”

“Pork and beef have been spit-roasted or boiled in clay pots but it surely seems to be as if the offal wasn’t at all times so properly cooked. The inhabitants weren’t consuming freshwater fish at Durrington Partitions, so that they will need to have picked up the tapeworms at their dwelling settlements.”
