Research
in Our Lab:
The research in our lab
is quite varied, but can be summarized as the study of the evolution,
extinction, systematics, and theoretical issues of living and extinct
vertebrates and their geological setting.
Over the years, others
students in our lab have examined the evolution and systematics of
kangaroos using postcranial data, examined the systematics of living
and fossil tapirs, studied the systematic relationships of river
dolphins and the question of monophyly of odontocete whales, analyzed
the phylogenetic relationships within the stork family, analyzed the
cytochrome B region of mitochondria in all extant equids with a special
interest in whether zebras are monophyletic, described and determined
the phylogenetic relationships of vertebrates from the Late Cretaceous
Williams Fork fauna of western Colorado to assess the biostratigraphic
context of this small but important fauna, studied early ungulate
evolution using information from the middle ear, examined the geologic
setting of a Pleistocene mammalian fauna from the Anza Borrego Desert,
studied the taphonomy and paleoecology of the intraformational
conglomerates at Dzharakuduk in the Kyzylkum Desert of
Uzbekistan, and completed a faunal analysis of a late Oligocene mammal
fauna from San Diego.

Tony
Harper joined the lab in the Spring 2009, from the
University of
California, Santa Cruz. Among other things, he is interested in
early mammal evolution and dental wear in these mammals.

CONTRATULATIONS.
Yue Zhang finished his MSc in the
summer of 2009 and
has moved to Ohio State University for his PhD. His thesis
project was on the richest mammal site from
the Late Cretaceous of southeastern Montana.
|
 |
CONTRATULATIONS. Josh Ludtke finished his MSc in the
summer of 2008 and
has moved to the University of Calgary for his PhD. His thesis examined the phylogenetic
relationship of agriochoerid
oreodontoids and their position among basal artiodactyls.

CONGRATULATIONS. Justin
Strauss successfully
defended his MSc in the late spring of 2008 on
the systematics of the Late Cretaceous and Paleogene cimolestids,
a eutherian group that has been implicated in the origin of taxa such
as carnivores.

|
CONGRATULATIONS.
Cory Jones finished
his MSc in the spring of 2008. His thesis project
dealt with the systematics of the extant and extinct North Amercan gopherine tortoises.

|
CONGRATULATIONS.
Selisa Lim successfully defended her MSc in the spring of 2007.
Her study was of the Eastlake mammal fauna collected by the San Diego
Natural History Museum from the Otay Formation in San Diego County.
This is a very rich early Arikareean fauna with many well-preserved specimens.

CONTRATULATIONS.
Cory Redman finished his MSc in the summer of 2006 and has moved to
Texas A&M for his PhD. His
thesis was on the taphonomy and paleoecology of the intraformational
conglomeratesthat
occur throughout the Bissekty Formation at Dzharakuduk,
Kyzylkum Desert, Uzbekistan.

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:
Field research in
recent years has 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. We have built a team composed of Uzbek,
Russian, British, American, and Canadian scientists (URBAC). We
are interested in what the faunas can tell us about the evolution,
ecology, and faunal turnover during this time. I am specifically
interested in the mammals in this fauna. In Uzbekistan we have
found and begun describing the oldest known representatives
(zhelestids) of the clade that gives rise to as many as seven orders of
extant mammals collectively termed Ungulata. This work has extended
this clade back 20 million years. We more recently completed
similar studies of a clade (zalambdalestids) that we believe gives rise
to extant rodents and rabbits, and a clade (asioryctitheres) that are
probably stem eutherians. Fieldwork has been sponsored by
the National Geographic Society, the National Science Foundation, and
the Civilian Research Defense Fund. I also 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/Tertiary 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.

Lecture December
15, 2009, San Diego Natural History Museum The history of
life is commonly represented either as a ladder (scala
naturae) or a tree. Although commonly associated with Charles Darwin,
representations of the tree of life predate by many years the
publication in 1859 of On the Origin of Species. Darwin used trees in
his private notebooks over 20 years prior, but it was Jean-Baptiste
Lamarck who first published an evolutionary tree of life in 1809. As
strange as it may seem, trees of life in the 19th century did not
always represent evolution. A number of these trees represented instead
multiple creations. Discover the iconography of both evolutionary and
creationist trees of life that almost certainly finds its roots in
trees. (49 minutes)
