我们考古小组所发现的文物证明,伊泰普地区最早的居民要追溯到更新世的后期。这个地区相当大,包括巴西的南里奥格朗德州、桑卡塔林纳州和巴拉那州、乌拉圭东岸共和国、阿根廷的北部和我国。更新世约结束于1万2千年前。当时气候十分寒冷干燥,不宜植物生长,野草和灌 The artifacts found by our archeological team prove that the earliest inhabitants of the Itaipu region date back to the late Pleistocene. This area is quite large, including in Brazil’s Rio Grande do Sul, in the regions of Saskatchewan and Paraná, in the eastern coast of Uruguay, in the north of Argentina and in my country. The Pleistocene Treaty ended at 12,000 years ago. At that time the climate was very cold and dry, not suitable for plant growth, weeds and irrigation
