domestic dog and cattle were already present, in Dissignac, microliths were associated with pollen evidence for clearances. Some scholars speculate that megalithic graves might go back to the Mesolithic, but this contention is difficult to prove, as most structures have been reused. Large numbers of microliths have been found under the chambered tomb of Dissignac :fr:Tumulus de Dissignac. Neolithic The westernmost extensions of the Villeneuve-Saint-Germain culture, based on a Linear Pottery culture tradition are found in eastern Brittany at Le Haut Meé. The use of schist from the eastern edge of the Breton Massif for bracelets in settlements in the Paris Bassin attests to widespread trade. A bracelet of polished stone found in a grave in the VSG-settlement of Jablines Les-Longues-Raies was made of amphibolite from the island of Groix in southern Morbihan, proves trade with local Mesolithic communities. The earliest long mounds date to the early-5th millennium (Barnenez). The early passage graves generally date to between 4000 and 3000 bc, followed by evolved passage graves between 3000-2500 bc. In the later part of the Neolithic, allées couvertes and simple dolmens became the predominant type of burial monument. Some passage graves are decorated with incised lines, of which Gavrinis is probably the best known example. Some scholars see an influence of the central European Linear Pottery culture in the finds from the longbarrows of Mané Ty Ec and Mané Pochat er Ieu (Morbihan), but this should rather be connected to the la Hoguette tradition, ultimately of Cardial extraction. Carn-pottery, thin walled round based deep bowls, often with applied crescents (croissants) is typical for early chambered tombs. It is found in Finistère, Morbihan and Loire-Atlantique. Middle Neolithic settlements include La Motte, La Butte-aux-Pierres and Lannic. They mainly concentrate on the Coast. The pottery shows Chasséen influences. Bowls are still round-bottomed, but with s-shaped profiles and vertically perforated lugs. Some geometric decoration occurs, but is rather rare. Vase-supports of Chassey-type are found as well, the Breton variety has been named the Er Lannic type and is characterised by triangular perforations, while the examples found in the Channel Islands show circular perforations. Other local pottery types include Castellic grooved ware, Souc'h-ware, and Colpo-type ware. Stone circles like Er Lannic (a double oval of standing stones and a ditch) sometimes contain settlement material and pottery of Chasséen-type. By the middle of the 3rd century, the Kerugou, upper and lower Conguel and Rosmeur/Croh Collé types
