GSA2015 ANNUAL MEETING & EXPOSITION
This session will examine late Paleocene–early Eocene Paleontology
hyperthermal events in terms of the response of critical ecosys-
tems to climate change in terrestrial, shallow marine, and T144. 200 Years and Going Strong: The Role of Paleontology in
deep-sea environments. Geologic Mapping (Posters)

In celebration of the 200th anniversary of the publication of
Polar ice sheets and sea ice as climate feedbacks in the Earth William Smith’s geologic map of Britain, this session illustrates
system are studied through geophysical interpretations, analyses of how fossils continue to be important to geologic mapping in the
marine sediment cores, and marine ice-sheet and ocean modeling. 21st century.
T142. The Middle Paleozoic World T145. Conodonts from Black Shales and Other Rocks: In Honor
Disciplines: Paleoclimatology/Paleoceanography; Paleontology, of Anita G. Harris
Paleoecology/Taphonomy; Stratigraphy
Advocates: Adam David Sproson; David Selby; James R. Ebert Disciplines: Paleontology, Biogeography/Biostratigraphy;
Paleoclimatology/Paleoceanography; Paleontology, Diversity,
This session will explore new research related to changes in Extinction, Origination
paleoclimatology, paleoceanography, paleoecology, sedimentology,
stratigraphy, geochemistry, and tectonic evolution during the Advocates: D. Jeffrey Over; Stephen A. Leslie; Randall C.
Silurian and Devonian periods. Orndorff; John E. Repetski
Conodonts continue to be in the forefront of research in
Paleozoic and Triassic rocks. All aspects of current conodont-
related research are welcomed; the session honors Anita Harris,
whose own research spanned most of the field.

T147. Biotic Interactions and Their Influence on Long-Term GSA TODAY | www.geosociety.org/gsatoday
Evolution
Disciplines: Paleontology, Diversity, Extinction, Origination;
Paleontology, Paleoecology/Taphonomy; Paleontology,
Phylogenetic/Morphological Patterns
Advocates: Paul D. Taylor; Lee Hsiang Liow
Biotic interactions such as competition, predation, and symbi-
osis are important ecological processes with consequences for
long-term evolution that require innovative approaches to infer in
the fossil record because they are seldom directly preserved.
