ABSTRACT

As part of an investigation of indigenous navigation in the Rio de la Plata basin, four dugout canoes were located in Uruguayan collections. They were recorded using a form, photographs, and drawings. Samples were taken for radiocarbon dating, and dates range from 253BP±20 to 105 ± 20 BP. The analysis of nautical features allows for possible identifications of origin, one canoe being local, and the other three assigned to a regional context. No conservation procedure has been applied to any of them to prevent wood decay. Photographic recording was used in two cases to produce preliminary 3D models for digital preservation. Uruguay is the only country in South America were traditional watercraft such as dugout canoes are no longer used. Ethnographic research from the region may help to understand our early maritime heritage.

摘要

作为对里约德拉普拉塔盆地土著航行调查的一部分，四艘独木舟位于乌拉圭收藏品中。它们是用表格、照片和图画记录下来的。取样进行放射性碳测年，测年范围为 253BP±20 至 105±20 BP。对航海特征的分析允许可能的起源识别，一个独木舟是本地的，另外三个分配给一个区域背景。没有对它们中的任何一个应用任何保护程序来防止木材腐烂。在两个案例中使用了摄影记录来制作用于数字保存的初步 3D 模型。乌拉圭是南美洲唯一一个不再使用独木舟等传统船只的国家。该地区的民族志研究可能有助于了解我们早期的海洋遗产。
