Earthen ridges that occur in the active Los Médanos de Coro dune fields of the Venezuelan Caribbean coast have been attributed either to anthropogenic or natural origins. Anthropogenic explanations have focused on their location, geometry, structure, and compaction, in the context of archaeological sites and artifacts throughout the dunes, to suggest an origin as causeways built by the extinct Caquetío people and/or their pre‐Hispanic ancestors. To assess this topic, geomorphic, physicochemical, and elemental analyses were carried out on the ridges and interdunal beaches and playas. The configuration, elevation, and composition of the ridges, along with three bulk sediment 14C dates that range 1900–3000 year BP, are here found to be most compatible with a natural origin as exhumed paleochannels. Past human occupants may, however, have used the features as causeways.

委内瑞拉加勒比海岸沿海沙丘中的土脊：是人为的还是自然的？

委内瑞拉加勒比海沿岸活跃的LosMédanosde Coro沙丘田地中出现的土坎被认为是人为或自然起源。在整个沙丘的考古遗址和人工制品的背景下，人为的解释都集中在它们的位置，几何形状，结构和压实度上，以表明起源是绝种的卡克蒂奥人和/或他们的西班牙裔先祖建造的堤道。为了评估该主题，在山脊，跨际海滩和海滩上进行了地貌，物理化学和元素分析。在这里发现这些山脊的构造，高度和组成，以及三个大块沉积物14C日期，范围为1900-3000年BP，在这里发现它们与自然来源的古河道最为相容。但是，过去的人类居住者可能会
