Basic information
Sample name: Spirit Cave (Layer 2)

Reference: C. Conrad, C. Higham, M. Eda, and B. Marwick. 2016. Palaeoecology and forager subsistence strategies during the Pleistocene - Holocene transition: A reinvestigation of the zooarchaeological assemblage from Spirit Cave, Mae Hong Son Province, Thailand. Asian Perspectives 55(1):2-27 [ER 3371]
Geography
Country: Thailand

State: Mae Hong Son


Coordinate: 19° 34' N, 98° 16' E
Time interval: Holocene

Max Ma: 0.00855

Min Ma: 0.007905

Age basis: radiocarbon (uncalibrated)

Geography comments: "Spirit Cave is located in the karstic upland region of Mae Hong Son Province, northwest Thailand"
Coordinates are not given in the text, they were instead taken from the Wikipedia article for the site
Dates for the site were obtained from nine "samples of bamboo charcoal" and published by Gormon (1970)
Two dates were obtained for Layer 2, ranging from 10160-7945 cal. B.P.

Environment
Lithology: limestone

Taphonomic context: cave,human accumulation

Archaeology: ceramics,stone tools

Habitat comments: "An initial survey of the three chambers that comprise the cave complex suggested an intact and rich archaeological deposit in the middle cave section"
"the middle cave proved promising for archaeological excavation, with cord-marked pottery sherds, flakes, and quartzite cores visible on the surface" and this chamber was subsequently excavated "between June and July 1966"
While "Gorman argued that hunter-gatherers used the cave relatively continuously" the high abundance of Hipposiderid bats in this layer "suggests humans did not occupy the site while bat bones accumulated"

Methods
Life forms: bats,carnivores,primates,rodents,ungulates,other small mammals,lizards,snakes,turtles,frogs,fishes,crustaceans

Sampling methods: quarry,screenwash,surface

Sample size: 145 specimens

Sampled by: C.F. Gormon

Years: 1966

Sampling comments: "Excavation used 1 m squares following the natural strata" and "fine-grained screening (1 mm mesh)" of the "5 layers at the site"
"After an interval of 48 years [since the original 1966 excavations] and 4 different storage locations at the University of Otago, only part of the original collection has been located"
Therefore, "the Spirit Cave assemblage is a subset of the original collection, it does not represent the complete assemblage"
"...our reanalysis deals with only a minute portion of the original assemblage excavated and recovered by Gorman"
