Irish Prehistory Rewritten: New DNA Tests Disprove “Kerry Cow” Cattle Evidence

Core Event
Researchers using protein-based biomolecular analysis have determined that bone fragments from Ferriter’s Cove on the Dingle Peninsula, long cited as the earliest domesticated cattle in Ireland, actually belong to a bear and a wild boar. The finding eliminates the only archaeological support for the presence of domesticated cattle—and by implication early farming communities—in Ireland before 4000 BCE.
Background & Context
Excavations at Ferriter’s Cove in the 1980s and 1990s uncovered several bone fragments dated to the terminal Mesolithic (8000-4000 BCE). These fragments were identified as cattle and became known as the “Kerry Cow,” a cornerstone of theories that Ireland’s hunter-gatherers had contact with continental Neolithic farmers. The interpretation shaped scholarly narratives about the Mesolithic-Neolithic transition in Ireland and Britain.
Data & Statistics
- The original material consists of a small assemblage of bone fragments stored at University College Cork (UCC).
- The new analysis employed Zooarchaeology by Mass Spectrometry (ZooMS), which identifies species through preserved collagen proteins.
- Results show the fragments derive from a bear and a wild boar, not domesticated cattle.
Official Statements & Responses
Verbatim Quotes
- “For at least four millennia, hunting and gathering people lived on the island, and there is a common conception that they left little trace and that we know very little about them - unlike the megaliths of Neolithic farmers, who are portrayed in ways that feel very familiar in Ireland,” — Dr. Moucheron, under the mentorship of Professor Graeme Warren
Conflicting Reports & Gaps
Earlier archaeological reports identified the Ferriter’s Cove fragments as cattle, forming the basis for the “Kerry Cow” hypothesis. The new ZooMS evidence directly contradicts those identifications, creating a clear shift in interpretation. No alternative claims of cattle presence at the site have been presented since the re-analysis.
What’s Next
Further biomolecular work is planned to determine whether the bear remains represent a brown bear or a polar bear, potentially offering new insights into Ireland’s prehistoric bear populations before their Bronze-Age extinction. The research team, involving University College Dublin (UCD), UCC, and the CNRS laboratory in Lille, France, will continue to re-examine other key Mesolithic collections with modern techniques.
