FAUNAL REMAINS FROM THE GRABERT SITE (12 PO 248): A MIDDLE WOODLAND OCCUPATION IN POSEY COUNTY, INDIANA.


The Grabert site is a small Middle Woodland habitation site and associated mound located in Posey County, near the confluence of the Wabash and Ohio rivers in extreme southwestern Indiana. During the summers of 1989 and 1990, the Indiana Historical Society, Indiana University, and the Glenn A. Black Laboratory of Archaeology provided support for intensive controlled surface collection, magnetometry, and limited test excavations at the Grabert site.

Analysis of the surface distribution of cultural materials within a grid of five by five meter squares documented the presence of three discrete concentrations of debris within the overall site area. Magnetic surveys conducted in the central site area revealed magnetic anomalies both within and outside of the central debris concentration. Block excavations conducted within the central concentration of surface debris identified several partial and overlapping arcs of postholes describing oval or circular structures. Two shallow basin-shaped and refuse-filled pits and two small bathtub-shaped roasting pits or earth ovens were identified to the north and east of the structural postholes. One of each of these feature types corresponded with magnetic anomalies. Test excavations of magnetic anomalies outside of the surface debris concentrations confirmed the presence of prehistoric features which had not been disturbed by plowing and were therefore not reflected in the surface distribution of cultural materials.

Diagnostic ceramic artifacts include thin-walled grog, limestone, and grit tempered ceramics. Most commonly these are cordmarked jars having smoothed-over rims and notched lips. Complicated stamped, rocker stamped, and zoned incised decorations occur infrequently. The lithic assemblage is dominated by lamellar blades and includes Lowe Flared Base projectile points. These artifacts are most similar to materials recovered from the Mann site (12 Po 2, located approximately 2 km south of the Grabert site), and can be readily differentiated from earlier Hopewellian manifestations of the Crab Orchard tradition (Kellar, J.H., "The Mann site and Hopewell in the Lower Wabash-Ohio Valley", in Hopewell Archaeology, edited by David S. Brose and N'omi Greber, pp. 100-107, Kent State University Press, Kent, Ohio, 1979).

Two samples of wood charcoal derived from feature contexts produced uncorrected radiocarbon ages of 1780 +/- 60 years: A.D. 170 (Beta-38550), and 1810 +/- 60 years: A.D. 140 (Beta-38551).

In 1991, an analysis was undertaken of faunal remains recovered by dry screening pit feature and posthole fill through one-quarter inch wire mesh. The goals of the analysis included the documentation of patterns of environmental exploitation and an assessment of the nature and duration of the occupation.

The faunal sample included 1120 specimens weighing 675 g. The vast majority of the vertebrate sample was fragmentary and burned, and only about 10 percent could be identified to the genus level. Only two invertebrate specimens were present (both unidentifiable mussel shells); one of which had been drilled for suspension or hafting.

Mammals constitute almost 90 percent of the sample identified to the genus level. Whitetail deer represents 49 percent of the mammals, and another 36 percent is represented by small forest or forest-edge species such as raccoon, oppossum, squirrel and rabbit. Reptiles, primarily represented by terrestrial turtles, comprise the second most numerous class in the sample. Birds and fish are rare in the sample.

This sample composition implies a pattern of environmental exploitation characterized by a focus on a narrow range of terrestrial mammal species, despite the ready availability of Ohio River and backwater slough resources. The high frequency of terrestrial turtles and the low incidence of migratory waterfowl implies an occupation restricted to the warm season.

Comparative data from other Middle Woodland sites in Indiana is lacking. However, comparison with well-analyzed and contemporary Middle Woodland faunal assemblages from similar environmental settings in the lower Illinois River valley suggests that the Grabert site assemblage, with its low species diversity and focus on a narrow range of terrestrial mammals, compares most favorably with short-term, specialized occupations rather than long-term base camp occupations.
