Abstract

--- - This communication analyzes the distribution of benthic foraminifera in the infralittoral zone of northern Chile located between 26 degrees and 29 degrees S at depths between 7 and 12 m. Twenty-six taxa have been identified, whose density is mainly conditioned by grain size and hydrodynamics of the environment. A comparison with other coastal sectors of the Pacific coast of South America allows us to identify the most representative species of this area from southern Chile to Colombia. The results obtained are very interesting for their possible application in the reconstruction of Holocene paleoenvironments in the Atacama Desert. - Esta comunicaci & oacute;n analiza la distribuci & oacute;n de los foramin & iacute;feros bent & oacute;nicos en la zona infralitoral del norte de Chile localizada entre 26 degrees S y 29 degrees S a profundidades entre 7 y 12 m.
