GSA 2017 ANNUAL MEETING & EXPOSITION
T39. Cushman Foundation Symposium: Microfossil
Mayhem—Murder, Misfortune, and More
Cosponsors: Cushman Foundation; Paleontological Research
Institution; GSA Limnogeology Division; Paleontological Society;
Geochemical Society; GSA Archeological Geology Division
Disciplines: Paleoclimatology/Paleoceanography, Limnogeology,
Archaeological Geology
Advocates: Miriam E. Katz; Francine M.G. McCarthy; Michelle
F. Goman
Microfossils (assemblages, geochemistry) are integral to a wide
range of human-related studies, from hominin evolution to murder
investigation. This session highlights innovative microfossil
applications to areas such as forensics, pollution, sea level, climate,
anthropology, and archaeology.
T40. Earth Life Transitions and Major Continental Biological
Events of the Phanerozoic
Cosponsors: GSA Soils and Soil Processes Interdisciplinary
Interest Group; GSA Sedimentary Geology Division;
Geochemical Society; Paleontological Society; SEPM (Society
for Sedimentary Geology)
Disciplines: Paleoclimatology/Paleoceanography, Paleontology,
Diversity, Extinction, Origination, Stratigraphy
Advocates: Lauren A. Michel; Erik L. Gulbranson; Neil J. Tabor
This session will highlight research about Phanerozoic biotic
transitions in terrestrial environments. Advances made through
multidisciplinary research and application of modern calibration
studies made with deep-time application are welcome.
T41. Geochemical Records of the Late Triassic to Jurassic
Earth System and End-Triassic Extinction
Disciplines: Paleoclimatology/Paleoceanography, Geochemistry,
Paleontology, Diversity, Extinction, Origination
Advocates: Morgan F. Schaller; Masayuki Ikeda
Novel geochemical approaches and applications are changing
our understanding of the Late Triassic Earth System. This session
explores those records of paleo-environmental change as they lead
up to, and through, the End-Triassic Extinction.
T42. Glacier and Ice Sheet Grounding Lines: Contemporary
and Past Observations of Grounding Line Processes,
Behavior, and Landforms
Disciplines: Paleoclimatology/Paleoceanography, Environmental
Geoscience, Geomorphology
Advocates: Nicholas D. Holschuh; Lauren M. Simkins;
Alexander Robel; John B. Anderson
By integrating model results with observations of both modern
and paleo grounding lines, this session aims to understand the
geologic, glacial, and marine processes that drive ice sheet
grounding line dynamics.

T43. High-Resolution Investigations of the Permian-Triassic
Transition
Cosponsors: GSA Sedimentary Geology Division; SEPM
(Society for Sedimentary Geology); Paleontological Society;
Paleontological Research Institution
Disciplines: Paleoclimatology/Paleoceanography, Paleontology,
Diversity, Extinction, Origination, Geochemistry
Advocates: Thomas J. Algeo; Hugo Bucher; Kimberly V. Lau
This multidisciplinary session aims at a better understanding
of interrelationships among biotic, volcanic, climatic, and oceano-
graphic events of the latest Permian to Early Triassic through
integrated high-resolution bio/chemo/chronostratigraphic studies.
T44. Insights from Microfossils, from Traditional to Novel
Approaches
Cosponsors: Cushman Foundation; Paleontological Research
Institution; Paleontological Society; GSA Limnogeology Division;
Geochemical Society
Disciplines: Paleoclimatology/Paleoceanography, Geochemistry,
Marine/Coastal Science
Advocates: Miriam E. Katz; Robert K. Poirier; Krystyna
Kornecki; Megan K. Fung
Traditional uses of microfossils are central to many research
applications, while novel geochemical approaches utilizing micro-
fossils have expanded recently. This session highlights traditional
and innovative microfossil applications in terrestrial and marine
environments, including modern analogs.
T45. Miocene-Pliocene Terrestrial Ecosystem Response to the
Climate System
Cosponsor: Paleontological Society
Disciplines: Paleoclimatology/Paleoceanography, Geochemistry,
Paleontology, Diversity, Extinction, Origination
Advocates: Kevin Uno; Tammo Reichgelt
Miocene-Pliocene climatic change shaped modern terrestrial
environments and holds clues for the planet’s future. We encour-
age research on climate-biota interaction that elucidates mecha-
nisms of ecosystem change during this period.
T46. North Pacific Environment and Paleoclimate from the
Late Pleistocene to Present
Cosponsors: GSA Sedimentary Geology Division; GSA
Quaternary Geology and Geomorphology Division; GSA
Archaeological Geology Division; GSA Limnogeology Division
Disciplines: Paleoclimatology/Paleoceanography, Quaternary
Geology, Geochemistry
Advocates: Lesleigh Anderson; Miriam C. Jones
Marine and terrestrial reconstructions of environment and
climate from the North Pacific region, including eastern
Asia, Alaska, and western North America, are encouraged to
explore patterns and linkages during the deglacial, Holocene,
and historic periods.
