This field trip takes participants down an exciting trail of deep time, exploring India’s magnificent prehistoric sites and Quaternary landscapes in Tamil Nadu, southeast India. The trail begins at the iconic Lower Palaeolithic site of Attirampakkam (~1.5 Ma) and continues through time, exploring Quaternary landscapes and sites spanning the Early to Late Pleistocene and early Holocene. Participants will engage with sites and artefacts that hold answers to questions related to population migrations, paleoenvironmental changes, geochronology and archaeology. The field trip traverses fluvial, colluvial, and aeolian landscapes ranging from the oldest sites in inland northern Tamil Nadu to the striking Teri red coastal dunes and enigmatic microlithic assemblages of the deep south. Participants will witness community outreach activities and visit museums, thereby gaining immersive experiences of landscapes and populations across time and space.
