Preliminary palynological and non-marine ostracod analyses were carried out on samplesfrom Codo Formation outcropping near the cities of Grajaú and Imperatriz, Maranhão State. According to those analyses it was possible to recognize an Aptian age based on the Sergipea variverrucata palynomorph biozone and Harbinia spp. 201-218 ostracod biozone. Paleoecological interpretations allowed to suggest a limnic paleoenvironment with high evaporation rates under arid and warm paleoclimatic conditions.
