| The smaller of these
              characteristic bird-form figures was next to and vertically
              beneath the larger one, facing in the same direction, at a depth
              of roughly 20 cm.  These have a hard leather-like texture,
              but are apparently composed of bituminous pitch, geologically very
              much out of natural context.  They
              were among the very first artifacts discovered at the site in
              1987, along
              with simple bifacially edged hand axes, a scraper, and a tool
              preform.  Within the folds of the larger piece was a hair
              about a centimeter in length, determined by microscopic
              examination to be probably human (imbricate scale pattern).
