Lineage Divergences from Fossils and Molecules.
Lineage divergence estimates from fossils and molecules sometimes clash.
This symposium brings together specialists from a broad range of disciplines,
paleontological and molecular, to discuss the various reasons for data
set incongruence and the different methods available to simultaneously
consider disparate sources of temporal information.

S3—New Uses for the Dead: Paleobiological
Contributions to Conservation Biology.
Paleontological and paleoenvironmental data provide vital information
on baseline conditions prior to human impact and on the long-term biotic
consequences of environmental change. This session will focus on utilization
of the fossil record in order to reveal the ecological and evolutionary
consequences of environmental perturbations at various time scales.

S4—Changing Perspectives of
Tertiary Paleobotany in North America.
Contributions will address the importance of radiometric methods and
tephrachronology for stratigraphic and temporal placement of Tertiary floras,
review the Tertiary megafossil record of major plant groups, and discuss
the role of taphonomy and leaf physiognomic methods in reconstructing Tertiary
paleoclimate, vegetation, and environments.

S5—Spatial and Temporal Resolution
of the Fossil Record.
The symposium will focus on the resolution and completeness of the

S6—Evolution in the Computer:
Artificial Life and Evolution Models.
Artificial life (A-life) research creates digital entities that possess
properties and operate under rules that are designed to simulate those
of biological entities and systems. "Evolution models," such as self-organized
criticality, have attempted to simulate large-scale diversity and extinction
dynamics. This session will bring together A-life researchers, evolution
modelers, and paleontologists to discuss common interests, such as the
origin of complex systems and behaviors.

S7—New Interpretations of Complex
This symposium will review the latest interpretations and models of
the ethology and ecology of morphologically intricate biogenic structures.
Traditionally regarded as records of a single or dominant behavior, many
workers now interpret them as something else: records of prolonged occupation/use
and of complex/variable behavior. Some may even be viewed as 'extended
phenotypes' (sensu Dawkins) of the trace producers.

S8—The Beginning of the Mesozoic.
The beginning of the Mesozoic is a unique time in Earth history enduring
two major mass extinctions within a time span of 40 million years. And,
yet the outcome of these mass extinctions was to initiate the great Mesozoic-Cenozoic
marine radiation, which continues unabated today. Contributions will address
phylogenetic, paleoecological, functional morphological, taphonomic and
paleoenvironmental aspects of this crucial interval in life's history.

S9—New Perspectives in Non-Mammalian
This symposium will showcase current research on non-mammalian synapsids.
The scope of papers is very broad, and can include, but is not limited
to, recent advances in synapsid taxonomy, phylogenetics, stratigraphy,
functional morphology, and paleobiology. Papers that use non-mammalian
synapsids in comparative, evolutionary, or methodological studies are especially

S10—Drilling Predation and
Demineralization Through Time.
The fossil record of drillholes has focused on Cretaceous through Holocene
evidence, yet there is a growing recognition and acceptance that drilling
has been a part of the marine ecosystem since the Cambrian. This symposium
will provide a forum for those interested in boreholes to present new material
on the paleontology, evolution, ecology, biology, and taphonomy of both
prey and suspected predators.

S11—Species-level and Community-level
Stability: Case Studies from the Dominican Republic Neogene.
Despite the recent interest in coordinated stasis and the examination
of paleoecological factors involved in evolutionary processes, few rigorous
species-level studies have been integrated with quantitative paleobiological
investigations of community change. This session will examine species-level
and community-level stability in the richly fossiliferous Neogene sections
of the Dominican Republic.

and Stratigraphy of the John Day Basin, Oregon, USA.
This symposium will address the stratigraphy, taxonomy of the floral
and faunal assemblages, taxonomy, and paleoenvironments and paleoecology
within the middle Eocene through late Miocene volcaniclastics of the John
Day Basin. Anticipated papers include: redefinition of the Physical Stratigraphy
of the John Day Group, Clarno, Mascall, and Rattlesnake strata; paleomagnetic
polarity of the Turtle Cove area, new paleosol work, and descriptions of
new local faunas.

S13—Future of Micropaleontology:
Application to Environmental Problems?
We will discuss the value of micro- and meioorganisms for a variety
of applications, many of which are not generally associated with traditional
micropaleontology (e.g., pollution monitoring). It may be presumptuous
to call such applications the direction of micropaleontology, but they
can help focus current discussions regarding the future direction of micropaleontology.

The advent of powerful desktop computers, web technology, and off-the-shelf
software has resulted in a recent proliferation of paleobiological research
databases. This symposium will present results of some of these efforts,
plus provide a forum for highlighting possibilities of integrating information
across paleobiology and other biodiversity databases.

T1—The Evolution of Eutrophic
and Oligotrophic Planktic Ecosystems.
The session will focus on ecosystems that developed in oceanic upwelling
conditions, with comparisons and contrasts between these ecosystems from
the Precambrian to the Recent. Talks will include those on graptolites,
radiolarians, evidence for upwelling from tree ring study, and the seasonal
switching from eutrophic to oligotrophic conditions in a modern upwelling

has been enhanced by utilizing new approaches with stable isotopes, large
databases of fossil occurrences, phylogenetics, geographic database management,
and integrated multi-disciplinary projects. This session will highlight
these innovative approaches and discuss the future directions of terrestrial

T4—Caribbean Mesozoic Biogeography:
Paleontological Constraints on the Formation and Early Evolution of the
This session will explore the Early Jurassic to Cretaceous Caribbean
biota for understanding the history of the opening of the Caribbean seaway
and communications between the Pacific and Tethys. This biota includes
invertebrates (ammonites, rudists, gastropods, calpionelids, etc.), plants,
and marine vertebrates (pterosurs, plesiosaurs, turtle, crocodyles, pliosaurs,
etc.) but is not well understood.

T5—The Evolution of Grass-Dominated
Ecosystems during the Late Tertiary.
The timing and nature of profound late Tertiary ecological changes
from forest to grasslands and from C3- to C4-dominated plant communities
are still debated. This session will integrate data from sedimentology,
stratigraphy, paleopedology, stable isotopes, paleobotany, and vertebrate
paleontology, to provide a synthetic picture and help identify questions
for developing future research.
