Past Field
Work:

URBAC Expedition Crew Fall 2006
Field site at
Dzharakuduk, Kyzylkum Desert, Uzbekistan. Fossil sites are in the
badlands
behind
the encampment in the middle of the photo. The two round
structures are called yurts.
For scale, the
largest yurt on the
left measures 7 meters in diameter and the highest point on the
escarpment is 150
meters above camp (Photo by Igor Danilov).

Recent
Research:
Nine field seasons from 1994
through 2006 concentrated on Late Cretaceous sites in Uzbekistan, a
former republic of the Soviet Union. These are approximately 90
million years old and preserve ecologies along the coast of ancient
shallow inland seas. The team was composed of Uzbek,
Russian, British, American, and Canadian scientists (URBAC). We
were interested in what the faunas could tell us about the evolution,
ecology, and faunal turnover during this time. I was specifically
interested in the mammals in this fauna. In Uzbekistan we
found and described the oldest eutherian dominated mammalian fauna in
the world. The National
Science Foundation, the Civilian Research
Defense Fund, and the National Geographic
Society sponsored the research. I continue my broader
interests in the analysis of extinction and faunal turnover that was
originally spurred by my work on vertebrate turnover at the
Cretaceous/Paleogene boundary. These studies have been broadened to
other intervals in the Late Cretaceous. Such studies also continue to
raise broader theoretical questions of how phylogenetic systematics
should play a role in the analysis of faunal turnover, including both
questions of extinction and speciation. Most recently research
has turned to questions surrounding how nature's order has been
represented in the Western and scientific traditions, beginning with
the Greeks and moving forward in time to modern ideas of systematic
representations.
