From the oldest inhabitants of the Brazilian territory (horticulturists and hunter-gatherer groups), the museum preserved several artifacts made of stone (flint, quartz and other minerals) and bones, such as projectile points used for hunting, axe blades of polished stone and other tools used for carving, scraping, cleaving, triturating, and piercing, in addition to artifacts of ceremonial use and adornments. Although objects made of wood, fiber, and resin were also produced, the majority of them didn't stand the test of time and are almost absent in the collection, except for some individual piecesnamely a woven straw basket covered by resin, only partially preserved, found in the southern coast of Brazil.
