Geography comments: "Kuumbi Cave is located in Kusini District, in the Unguja South Region of Tanzania. It is located near the southeastern coast of Unguja Island, part of the semi-autonomous province of Zanzibar, c. 2.5 km from the present day shoreline".
"Charcoal from Phase 4 is dated to 16,656 ± 56 BP (c. 20,240 to 19,880 cal. BP)".

Environment
Lithology: limestone

Taphonomic context: cave

Habitat comments: "Kuumbi is a large solutional cave, one of several in a series of Pleistocene-era marine terraces on limestone. Five main phases were identfied in the main trench: Phase 1a contains large limestone lithics and Swahili ceramics; Phase 1b contains the same lithics and earlier Tana Tradition/Triangular Incised Ware ceramics; Phase 2 does not contain any ceramics but includes Later Stone Age (LSA) bone projectile points and other bone tools and a quartz microlithic industry; Phase 3 contains similar LSA quartz and bone technologies; Phase 4 does not bear any unambiguous evidence of human occupation, but it does contain faunal remains, a few of which are burned".

Methods
Life forms: bats,carnivores,primates,rodents,ungulates,other large mammals

Sampling methods: quarry,screenwash

Sample size: 65 specimens

Years: 2012

Sampling comments: "Four trenches were excavated in Kuumbi Cave during the Sealinks field season in 2012: Trench 10 was located in the upper main chamber. All deposits from Trench 10 were dry-sieved on site using 3 mm mesh, except for sub-samples of between 7–60L per context; these were bagged separately and processed by flotation to recover archaeobotanical remains and subsequently wet-sieved through 1mm mesh. The wet- and dry-sieved faunal samples (excluding land and marine molluscs and fish) were included in the analysis, for a total of 17.6 kg of tetrapod faunal remains".
