Extended Data Fig. 1: Liang Tebo cave topography and site plan.
From: Surgical amputation of a limb 31,000 years ago in Borneo
a, Liang Tebo is a cathedral-sized (~160 m3) limestone cave with three large chambers. Following GPR and ERT survey, a 2 x 2 m excavation was positioned over an area of likely deep deposit in the centre of the caves’ lower and largest chamber. This area was excavated to a depth of 1.5 m before the project was forced to cease, following the COVID19 pandemic. The human burial (TB1) was excavated in its entirety before the field season was terminated. b, The uppermost chamber of the cave contains pigment rock art, including negative hand stencils, shown modified using D-Stretch. c, View of excavation square in lower chamber looking south towards upper chamber 1. d, View from upper chamber 1 looking northeast into lower chamber. e, Liang Tebo north cave mouth showing rainforest vegetation outside of the dripline.
