Anthropologists Martha Benavente
and Alejandro Terrazas of the Insti-
tuto de Investigaciones Antropoló-
gicas in Mexico City examine human
bones which were just recovered
by divers from a site 42 m deep in
The Pit. The bones are roughly
13,000 years old. They are kept in
water lest they turn to dust. The
matching skull was brought to the
surface only minutes later.
