The Woodland period (2500 BCE-900 CE) is divided up fundamentally into the Deptford culture (2500 BCE-100 CE), Swift Creek culture (100-300 CE), Santa Rosa-Swift Creek culture (100-300 CE), and Weeden Island culture (300-900 CE) cultures. It is characterized by and widespread use of pottery (and tempering agents) which began in the late Archaic period. Also, the increasing sophistication of pottery forms and decoration began. The increasing use of agriculture also meant that the nomadic nature of many of the tribes was supplanted by permanently occupied villages, although agricultural development did not really advance until the Mississippian period. Burial of the deceased in mounds with elaborate grave goods also began.
