Stonehenge Stone Circle News and Information

The paper, published in The Journal of Archaeological Science, examined a cow’s jawbone that was discovered in 1924 beside Stonehenge’s south entrance. Using isotope analysis of one of its teeth, the researchers dated it to around the time of the monument’s beginning, between 2995 and 2900 BCE, and placed its likely origin in Wales.

This is the first time that scientists have seen evidence linking cattle remains from Stonehenge to Wales, adding further weight to theories that cows were used in the transportation of the enormous rocks across the country. Previous research has shown that Stonehenge’s bluestones originated in Wales.

Professor Michael Parker Pearson (UCL Archaeology) said: “This is yet more fascinating evidence for Stonehenge’s link with south-west Wales, where its bluestones come from. It raises the tantalising possibility that cattle helped to haul the stones.”

The scientists sliced the cow’s third molar tooth, which records chemical signals from the animal’s second year of life, into nine horizontal sections. They were then able to measure carbon, oxygen, strontium and lead isotopes, which each offer clues about the cow’s diet, environment and movement.

The different concentrations and varieties of elements embedded within the tooth provided insight into the cow’s life. The oxygen isotopes revealed that the tooth captured roughly six months of growth, from winter to summer, whilst the carbon isotopes showed the animal’s diet changed with the seasons: woodland fodder in winter and open pasture in summer. Additionally, the strontium isotopes indicated the seasonal food sources came from different geological areas, suggesting that the cow either moved seasonally or that winter fodder was imported.

The lead isotopes revealed composition spikes during the late winter to spring, pointing to a lead source that was older than the lead in the rest of the tooth. The composition suggests the cow originated from an area with much older Palaeozoic rocks, such as around the Preseli hills in Pembrokeshire, Wales, where the Stonehenge’s bluestones originated before being transported to Sailsbury Plain.

Professor Jane Evans, BGS Honorary Research Associates said: “This study has revealed unprecedented details of six months in a cow’s life, providing the first evidence of cattle movement from Wales as well as documenting dietary changes and life events that happened around 5,000 years ago. A slice of one cow tooth has told us an extraordinary tale and, as new scientific tools emerge, we hope there is still more to learn from her long journey.”

In addition, researchers also concluded that the unusual lead signal could not be explained by local contamination or movement alone. Instead, that lead stored in the cow’s bones had been remobilised during the stresses of pregnancy. If true, this would mean the cow was female and pregnant or nursing during the tooth’s formation. To test the hypothesis, the team applied a peptide-based sex determination technique at the University of Manchester, which showed there was a high probability that the animal was female.

Richard Madgwick, professor of archaeological science at Cardiff University, said: “This research has provided key new insights into the biography of this enigmatic cow whose remains were deposited in such an important location at a Stonehenge entrance. It provides unparalleled new detail on the distant origins of the animal and the arduous journey it was brought on. So often grand narratives dominate research on major archaeological sites, but this detailed biographical approach on a single animal provides a brand-new facet to the story of Stonehenge.”
