Troyville-Coles Creek
The Troyville-Coles Creek Period lasted from approximately A.D. 400 to A.D. 1100. By the beginning of this period, influence from the Ohio-Illinois Hopewell people had ceased, and pottery styles, mound building, and ceremonial life had gradually changed.
The Troyville-Coles Creek people continued building ceremonial centers with mounds, but these mounds differed from earlier ones. They were larger, shaped differently, and more numerous. They also served a new purpose. Instead of being primarily for burials, these mounds were constructed to support temples or civic buildings. Pyramidal mounds with flat tops, and sometimes with stepped ramps leading up one side, came into style. They were constructed over hundreds of years, and usually were enlarged one or more times. Although the total height might reach only 20 feet, the base might eventually be enlarged to more than 200 feet on each side. At certain sites, three to nine mounds eventually were built, all around an open, central plaza.
A temple and one or more other buildings were usually built on a mound summit. These buildings were either circular or rectangular with walls of wattle and daub. Wattle is a construction technique whereby branches, twigs, cane, or vines are interlaced around upright posts that have been sunk in the ground. These are then plastered with mud or clay daub. The Troyville-Coles Creek people probably used grass thatch or palmetto fronds for the roof.
Greenhouse Site
The Greenhouse Site, in Avoyelles Parish, is the most extensively excavated site that is typical of the Troyville-Coles Creek Period. Seven earthen mounds there surround an open plaza that measures 200 feet by 350 feet. No village or campsite remains were found in the plaza or outside the mound area. This leads archaeologists to conclude that the mound group was used for ceremonial activities only, and that villagers lived elsewhere.
Some people were buried in the mounds, but in contrast to Marksville burials, the bodies were not accompanied by a rich assortment of objects. One or more bodies were buried in pits, or simply laid upon the mound summit and covered with dirt. People were also buried in village areas away from the mounds. Why some were buried in the mounds and some were not, remains a mystery. It may be that people associated with mound construction, with temple activities, or those of significant social status were buried in the mounds. Alternatively, if many people died from illness, famine, or disaster, that might have signaled a time for special ceremonies and mound enlargement. Those victims might have been buried in a mound.
Villages and campsites were often a mile or more from these ceremonial centers. There, daily life was more focused on maintaining a stable food supply than on ceremonial activities. During the Troyville-Coles Creek Period, important changes in hunting techniques and garden crops helped guarantee this food supply.
It was during this period that the bow and arrow came into use in Louisiana. First invented in Europe thousands of years before, bows and arrows were gradually adopted by people in Asia and eventually by people in North America. The introduction of the bow and arrow meant hunters could shoot further, more accurately, and with more firepower than before. The arrow points were generally smaller than those used on spears. These then, were the first true arrowheads made in Louisiana.

Troyville-Coles Creek people also continued using the atlatl, as well as the traditional butchering and hideworking tools that had been made since Meso-Indian times. There was no dramatic change in the types of animals hunted during this time. The Indians killed game such as deer, bear, small mammals, and game birds. They also ate fish and mollusks as had their ancestors.
The Troyville-Coles Creek people continued collecting wild seeds, fruits, roots, and other plant foods. They cultivated squash, gourds, and native plants such as sunflowers and lamb’s quarters, but a most important addition to these garden crops was corn, which had been domesticated earlier in Mexico. The Indians no doubt experimented with it for many generations, developing strains and cultivation techniques best suited to Louisiana conditions. Certain plant foods were still ground with mealing stones and probably stored in pottery vessels.
In this period, pottery styles changed, producing more durable pots with more diversified uses. The Troyville-Coles Creek Indians tempered their clay with particles of dried clay before coiling it to shape the pot. They specialized in rounded or barrel-shaped jars and in deep or shallow bowls. The potters removed coil marks by patting the surface with a smooth wooden paddle.
Sometimes they used a carved wooden paddle to stamp designs onto the entire outer surface of the vessel. At other times they decorated only the top half of the pot with designs formed by incising lines or pressing tools into the damp clay. The colors of the clay were usually tan, brown, gray or black. On rare occasions vessels were colored red on the outside or shaped into human effigies.

Late in the Troyville-Coles Creek Period, changes began to occur. Indians in the northwestern part of the state developed close ties with people living north and west of them, while those in the east became more closely aligned with people to their east. Descendants of the Troyville-Coles Creek people were Indians of the Caddo and of the Plaquemine-Mississipian cultures.
