Studying microscopic layers of dirt dug from the Tam Pà Ling cave site in northeastern Laos has provided a team of Flinders University archaeologists and their international colleagues further insights into some of the earliest evidence of Homo sapiens in mainland Southeast Asia.
The site, which has been studied for the past 14 years by a team of Laotian, French, American and Australian scientists, has produced some of the earliest fossil evidence of our direct ancestors in Southeast Asia.

Now a new study, led by PhD candidate Vito Hernandez and Associate Professor Mike Morley from the College of Humanities, Arts and Social Sciences, has reconstructed the ground conditions in the cave between 52,000 and 10,000 years ago.
“Using a technique known as microstratigraphy at the Flinders Microarchaeology Laboratory, we were able to reconstruct the cave conditions in the past and identify traces of human activities in and around Tam Pà Ling,” says Hernandez. “This also helped us to determine the precise circumstances by which some of the earliest modern human fossils found in Southeast Asia were deposited deep inside.”
Microstratigraphy allows scientists to study dirt in its smallest detail, enabling them to observe structures and features that preserve information about past environments and even traces of human and animal activity that may have been overlooked during the excavation process…
