Some time before 4,000 BC, Neolithic settlers introduced cereal cultivars, domesticated animals such as cattle and sheep, built large timber buildings, and stone monuments. The earliest evidence for farming in Ireland or Great Britain is from Ferriter's Cove, County Kerry, where a flint knife, cattle bones and a sheep's tooth were carbon-dated to c. 4,350 BC. Field systems were developed in different parts of Ireland, including at the , that has been preserved beneath a blanket of peat in present-day Tyrawley. An extensive field system, arguably the oldest in the world, consisted of small divisions separated by dry-stone walls. The fields were farmed for several centuries between 3,500 BC and 3,000 BC. Wheat and barley were the principal crops.
