Azilian decorated pebbles have been found, as well as some geometrically decorated bones and plates. Additionally personal ornaments, made up of teeth or shells, are common as well. Neolithic The Neolithic is characterized by agriculture and animal husbandry. In the Basque Country it was a late arrival, leaving its inhabitants in a subneolithic situation almost until the beginning of metallurgy in most of the territory. The earliest evidence of contact with Neolithic peoples is in Zatoia, northern Navarre, with pottery remains dated to c. 6000 BP. The first evidence of domestication appears in Marizulo (Gipuzkoa) c. 5300 BP. These innovations gradually expanded, though hunter-gathering activities remained being important. Overall the vast majority of important Neolithic sites are placed in the southern part of the country (Ebro valley): Fuente Hoz, Peña Larga, Berniollo and La Renke in Araba; Zatoia, Abauntz, Peña, Padre Areso and Urbasa 11 in Navarre; Herriko Barra in Gipuzkoa. In the early phases there is only evidence of domestication of dogs. In the advanced Neolithic, remains of ovis and capra are found in sites like Fuente Hoz (Araba) and Abauntz (Navarre). In the late phase, oxen and pig are found as well. Seafood gathering remained being an important source of food in the coast. Lithic industry shows total continuity with the Epipaleolithic (geometric microliths) but some new elements, like sickles and hand mills, begin to appear as well. Stone polishing makes in this period its first appearance, becoming more frequent at later dates. Pottery was initially scarce, yet it became more common and variegated at the end of Neolithic (c. 3000 BCE). Burial customs became more defined in this period, using specific burial spots like dolmens, mounds or caves. A remarkable case is the massive burial site under rock of San Juan Ante Porta Latinam (Araba) that included 8,000 bone remains, belonging to at least 100 individuals. The human type is sometimes defined as Western Pyrenean. Chalcolithic The Chalcolithic (Copper and Stone) period, also known as Eneolithic or Copper Age, lasts in the Basque Country from c. 2500 to c. 1700 BCE. While hunting was still of some importance, especially in mountain areas, food production became finally dominant. Lithic industry persists but some tools were already made of copper (axes, knives, etc.). Gold is also used for ornaments. An important phenomenon in the late Chalcolithic is the Bell Beaker phenomenon of pan-European extension. Also through all the period
