Gladysvale
In 1991, while still a graduate student, I "rediscovered" the site of
Gladysvale in the Cradle of Humankind.  It was readily apparent from
the abundance of fossils that this site could prove important.  I began
excavations with the assistance of my students in the Department of
Anatomy at the University of the Witwatersrand.  After just a couple
of weeks we discovered some fossil teeth of early hominins.  This
find made Gladysvale the first new hominin site to be discovered in
southern Africa since 1948.  Since then we have continued work at
Gladysvale and have recovered many thousands of fossils and have
advanced our understanding of the geology of the cave.  Because of
the clear stratigraphy at the site, we have also been able to
experiment with and test a wide variety of dating techniques that
have proven important in understanding which methods work, and
which don't, on the South African fossil sites.  At Gladysvale, I work
closely with colleagues from the University of Zurich, the University
of Arkansas and Duke University and many of my students have
completed Masters and Ph.D.'s on topics originating from this site.
