Las investigaciones realizadas en diferentes yacimientos de la costa septentrional bonaerense aportaron una serie de datos de singular inter&eacute;s sobre culturas alfareras que se asentaron a lo largo del &aacute;rea mencionada.<br /> Las excavaciones efectuadas en Punta Indio, Palo Blanco, Punta Lara, Pereyra y Hudson, nos permitieron distinguir tres fases con cer&aacute;mica, Litoral bonaerense primitiva, Litoral bonaerense cl&aacute;sica y Litoral bonaerense tard&iacute;a. La diferenciaci&oacute;n de estas tres fases est&aacute; establecida por pruebas estratigr&aacute;ficas y geol&oacute;gicas.<br /> La fase Litoral bonaerense primitiva se identifica por una cer&aacute;mica sencilla, sin decoraci&oacute;n ni pintura. Esta fase est&aacute; relacionada con el &uacute;ltimo cord&oacute;n conchil de la ingresi&oacute;n querandinense.<br /> La fase Litoral bonaerense cl&aacute;sica est&aacute; caracterizada por la alfarer&iacute;a grabada y pintada. En la zona de Punta Lara esta fase est&aacute; asociada a una rica tipolog&iacute;a de material l&iacute;tico trabajado en cuarcita. Los sitios t&iacute;picos que hemos excavado corresponden a los de la zona de Punta Indio. Se extiende esta fase por toda la costa septentrional bonaerense y el borde de las lagunas que corren paralela a la zona mencionada.<br /> La fase Litoral bonaerense tard&iacute;a, identificada en Punta Lara, Pereyra, se distingue por la cer&aacute;mica t&iacute;picamente guaran&iacute;. Los yacimientos en el &aacute;rea en estudio son escasos y los materiales que caracterizan a esta fase aparecen, la mayor&iacute;a de las veces, en forma superficial.A number of singularly interesting facts referring to pottery in Communities that existed along the North bonaerense coast were brought about by investigations performed in that area.<br /> The excavations we made in Punta Indio, Palo Blanco, Punta Lara, Pereyra y Hudson allowed us to find out three different phases with pottery in them, Primitive Litoral Bonaerense, Classical Litoral Bonaerense and Late Litoral Bonaerense. The differences among these three phases have been established by stratigraphical geolegical test.<br /> Plain pottery lacking ornamentation and paint, and cocked in an oxidanf and reducing atmosphere identifies the Primitive Litoral Bonaerense. This phase is related to the last ridgesot rock-shell of the &ldquo;ingresi&oacute;n querandinense&rdquo;.<br /> Pottery engraved and painted without ornamentation is the main feature in the classical Litoral Bonaerense phase. In Punta Lara area this phases connected with a rich typology of lithic material, mainly developed in quartzite. We have excavated in the typical places corresponding to the area of Punta Indio. This phase appears all along the Northern bonaerense coast, and the edges of the ponds that lie alongside this area.<br /> The Late Litoral Bonaerense appears in Punta Lara, Pereyra and its main feature is the typical guaran pottery. The field in this area are scarce and the elements which characterize this phase appear superficially most of the times.
