Salvage excavations conducted between to have yielded one of the largest and best-preserved skeletal assemblages in the central Illinois River valley.

The human skeletal assemblage from the Orendorf site has been ideal for a wide variety of bioarchaeological research, both invasive and non-invasive. Despite the attention given to the individuals, research focusing on the burial contexts and radiometric dating of the burials are lacking.

Through georectification of spatial data from the original excavation paperwork, I have identified seven individual burials from distinct stratigraphic episodes within burial Mound excavated between and for radiocarbon dating to establish a chronology for the Orendorf mortuary complex to compliment radiometric dating from the village settlements. Figure 5: Mound stratigraphy as outlined in Anderson and Bainter Four stages of mound construction were Figure 7: Probability distributions for sampled Orendorf burials Figure radiometric dating is a complex process complicated by Calibrated ranges of all published and unpublished dates for noted, as well as the location of the Blasingham excavation Fig.

Comparison of these new dates from the burials to other published and unpublished dates shows the burials leaning earlier than nearly all other materials dated Fig. This may be suggestive of a biomolecular process similar to the reservoir effect in marine animals that may be affecting carbon decay rates.

For example, Burial a Mississippian village and mortuary complex that includes four sequentially tested positive with aDNA related to the mycobacterium complex i. The early five of the mounds originally noted, including Mounda burial mound Fig. Emily Blasingham conducted the first professional excavations of Mound region, as well as occupation at Orendorf.

Besides Burial 89, the dates presented from in Conrad Due to increased looting of Moundexcavations were the mortuary complex are largely in agreeance with previous published dates from conducted between and Anderson and Bainter Collectively, the village settlements. The addition of the mortuary complex dates to the series of one-third of Mound was excavated Tatchellproducing one of the dates from the village settlements provides a more comprehensive timeline of largest and best-preserved skeletal assemblages within the region.
