burial of the first series. The barrows of the second series are a bit smaller and show a more inland-distribution. They do not normally contain metal, but numerous pottery vessels, high biconical vessels, sometimes with a geometric decoration under the rim, or single four-handled undecorated pots. There seems to be no division of the grave goods by gender. Glass-beads are found in some graves, for example at Mez-Nabat, Plouhinec (Finistère). A number of radiocarbon-dates are known from the barrows: The later part of the early Bronze Age saw the beginning of the exploitation of the Armorican tin deposits. Numerous hoards contain tools and weapons, but metalwork is rarely found in burials or settlements, which makes the synchronisation of hoards and settlements difficult. The Tréboul-group of hoards is thought to be contemporaneous with the second series barrows. Decorated spear-heads, flanged axes, palstaves and long daggers are typical. The hoard from Bignan (Morbihan) contained only bronze jewellery. Coastal salterns are known from the late Bronze Age onwards as well, for example at Curnic, Guissény. Pollen analysis shows that widespread clearance of the beech forests took place in the early Bronze Age. Cereal pollen have been found at Porsguen, Plouescat, for example. Domestic animals included sheep, goats and cattle, but hunting may have still provided a lot of meat. La Roche, Videlles, has still 60% wild animals among the animal bones, but it is not clear if this is typical. Carbonised remains of naked wheat and barley have been found at Plounéour-Trez, hazelnuts and acorns were eaten as well. Flint still formed an important part of the tool inventory. Some standing stones (Menhirs) and stone alignments date to the early Bronze Age, for example the Grand Menhir Brisé at Locmariaquer. The later Bronze Age sees only a slight Urnfield influence. Hoards are numerous. The Saint-Brieuc-des-Iffs phase marks the beginnings of the Atlantic bronze industries. It is succeeded by the carp's-tongue complex, found in Britain and Portugal as well. The square-socketed armorican axes turn up in hoards in great numbers. At Maure-de-Bretagne, over 4000 axes have been found, ca. 800 at Tréhou and Loudéac. The axes are mainly unused and may have been a form of ingot of primitive currency. They contain a high amount of lead or consist of pure lead and are distributed from the Iberian Peninsula to eastern Germany, Ireland and Southern Britain, with some pieces from Scotland, Poland and Switzerland.
