Geography comments: "Fa-Hien Lena is located in Sri Lanka’s Wet Zone region, near the town of Bulathsinhala, 75 km southeast of Colombo in a lowland evergreen rainforest environment".
Phase B dates to the Early Holocene, from c. 8700 to 8000 cal. BP, based on five radiocarbon dates ranging from 7, 720 ± 40 to 6, 900 ± 40 BP.

Environment
Lithology: siltstone
Taphonomic context: cave, human accumulation
Archaeology: bone tools, hearths, stone tools
Habitat comments: "The cave, on the slope of a gneiss cliff, has a c. 30 m by 20 m east-facing entrance, an interior that extends c. 10 m into the cliff, and two main chambers (termed shelters A and B). The site is divided into four distinct phases, corresponding to concentrations of charcoal, faunal remains, and artifacts, including osseous tools, shell beads, and quartz flakes; each represent the major periods of human occupation of the cave".
"Phase B consists of two distinct lithostratigraphic units separated from the Terminal Pleistocene deposits by a sharp boundary that truncates underlying strata. The first unit consists of a series of subhorizontal layers of light brown sandy silts, matrix-supported collapse breccia and ash accumulations, with a moderate amount of artifacts and habitation debris. The second unit includes a large multi-stage pit. The pit consists of multiple layers of sandy silt and steeply-dipping accumulations of ash with abundant charcoal".

Sampling comments: "Fa-Hien Lena was systematically excavated over several seasons from 1986 to 1988, and from 2009 to 2012. The paper presents the results of the analyses of materials from the 2009 to 2012 excavations. Shelter A, the larger of the cave’s chambers, was excavated to a depth of over 6 m". No further excavation details are provided, although "all bone fragments from sedimentary contexts with secure radiocarbon dates were included in the analysis".
