Summary
The submerged cave chamber of Hoyo Negro contains a diverse assemblage of human and faunal skeletal remains dating to the Late Pleistocene. Many of the represented animals became extinct at least 10,000 YBP. The human skeleton is that of a young girl who ventured into the cave at least 12,000 YBP. Most of these deposits are extraordinarily well preserved. Detailed recording of this chamber is difficult, as the site is completely dark and at maximum depth of 57m. Over the past two years, the team has constructed multiscale 3D point-cloud models using structure-from-motion (SfM) techniques. The site-scale approach captured a 60m diameter area at the bottom of the pit. A series of deposit-scale SfM models were created around selected bone deposits and features. The images acquired of the human skeleton produced an extremely dense and highly accurate point-cloud, which has made possible in situ taphonomic analyses of the site.
