This is the Cane Patch site on the GA coast. A shell heap once 65m across, 10m tall. Accumulated 4k yrs ago by Indigenous people living in the earliest permanent villages in North America. Cane Patch likely served as an important place for new villages to maintain wider social networks #archaeology

Drs. Jake and Isabelle are in DC at the Smithsonian NMNH! They’re dropping off 400yr-old peach pits from an Ancestral Muskogean site on the South Carolina coast to test for DNA preservation. Hoping to learn more about Indigenous management of this important plant! #archaeology #ecology #aDNA 🧬

After fieldwork on the Georgia coast and in Mongolia, PhD student Matt Picarelli-Kombert spent time at UGA analyzing collections for his dissertation. Matt explores the impacts of Emancipation on Gullah-Geechee foodways and relationships to estuarine ecosystems along the Atlantic coast! #archaeology

Some 5,000yr old fish bones. These were found in a massive shell mound along the Georgia coast. This place (and the institutions it represented) likely served a socially integrative function, as it dates to the time of shell rings, the earliest permanent villages in North America! 🐠 🐟 🦴 #archaeology

This summer, lab member and Ecology PhD student @willvuyk.bsky.social collected sediment cores from freshwater ponds on Ossabaw Island along the Georgia coast. He will be analyzing sedaDNA/eDNA to track deep-time human-ecosystem dynamics! @microarch-lab.bsky.social #archaeology #ecology

The earliest known pottery made north of Colombia, c. >4,500yrs old. Ancestral Muskogean potters along the US Atlantic coast added Spanish moss to the clay and decorated with all kinds of techniques. These impressions may have been made using a marsh periwinkle (snail) shell #archaeology #history

The SAHND half of the lab is @archaeojake.bsky.social! He explores deep histories of human governance; leveraging approaches that include precise chronology building, network analyses, and archaeometry to study these creative human forms, from collective states, to mobile empires, to autocracies.

Meet @isazooarch.bsky.social! Faculty in Anthropology and Ecology (and Curator of Zooarchaeology @ the Matson Museum). She explores the ecologies and economies of island, coastal, and wetland societies, with a special focus on 🐠 , 🦪 , and ⚛️ (among other traditional and specialized approaches!)

Our lab of archaeologists, historians, and ecologists studies social, economic, and environmental dynamics over the last 5,000yrs. From the earliest Indigenous villages on the US Atlantic coast, to nomadic Mongolian empires, to Black towns of the post-emancipation South. Follow for rad archaeology!
