In northeastern Louisiana, near Epps, is an ancient village site called Poverty Point. It contains a unique bird effigy mound and a large geometrical village. Houses of palmetto were built on ridges of earth arranged in an octagon east of the 600 foot long and 70 foot high bird mound. Since they did not have clay pottery, food was cooked by placing it in an earthen pit lined with hot baked clay balls. Tools, called micro-flints, were made from stone slivers to open shellfish, nuts, and seeds. There are also indications of developing trade with other areas. _Tchefuncte Period_ (200 BC-400 AD): In coastal Louisiana much of the old Archaic tradition of shellfish gathering, augmented by hunting, continued long after the Poverty Point culture was 1,000 years old. About 200 BC crude pottery was added to the basic Archaic Culture on the coast and around Lake Ponchartrain. They continued to eat shellfish, supplemented with small game and wild plants. They lived on shell middens in circular houses made from poles and thatch. _Marksville Period_ (100-550 AD): The development of agriculture during this period freed the early Louisianians from daily hunting and food gathering which allowed them time for more religious and recreational activities. They began making fine pottery and flint projectile points for ceremonial and burial purposes rather than for purely utilitarian uses. They continued building earthen mounds and added rather elaborate burial practices by placing the deceased in the mound with pottery and recreational items such as chunkey stones. Some of these burial artifacts were made from materials from as far away as Yellowstone Park and marine shells from the Gulf. Their artifacts included copper items. _Troyville-Coles Creek Period_ (500-1200) This was basically a continuation of the Marksville Period. Mound building became more advanced with a shift toward large flat topped pyramidal mounds as foundations for temples. These were probably used for sacred and ceremonial activities. The burial mounds continued to be built in conical shapes. Agriculture improvements included clearing fields by slashing the trees and burning them in the fields to provide fertilizer for crops. Bows and arrows were used for the first time which increased their hunting successes. With these improvements came larger populations as the people developed methods for feeding their growing numbers. It also meant time for improving the art of pottery making. Archaeologists are able to tell the tribe and with whom they traded by examining the styles of decoration and the lines incised on the pottery. _Plaquemine Period_ (1100-1450) Maize agriculture was important during this period. Villages were located on bluffs and terraces near large streams and rivers to utilize the rich alluvial bottom land for farming and water for the villagers.
