Abstract
The marsh deposits cropping out near Galerazamba are located at 15 m above sea level and at a distance of 1,250 m from the present day Ciénaga El Totumo. This location suggests frequent changes in the sea level. A radiocarbon age of 4,150±50 yr BP was obtained from mollusc remains at the Ciénaga El Totumo. The age of the marsh corresponds to a dry climate period according to paleoenvironmental data from the northern part of South America. The Ciénaga El Totumo retreated during this dry episode. The fossil biota content found in these raised marsh deposits is poorly diversifed and corresponds to the inner part of the marsh.
Keywords: Marsh deposits; Ciénaga El Totumo; Colombia; Late Holocene; Molluscs; C-14.
