The relationships of supercontinents to mantle convection and plumes, geomagnetic reversal frequency, and true polar wander. Supercontinents and their effects on ocean circulation, eustasy, paleoclimates, and biological evolution. Comparrative tectonics of Archean, Proterozoic,and Phanerozoic supercontinents.
Note: Expected to be given in 2001–02.
Prerequisite: Two of EPS 5, EPS 7, EPS 8, or permission of the instructor.

Earth and Planetary Sciences 281r (formerly Earth and Planetary Sciences 281). Snowball Earth Phenomena
Catalog Number: 2474
Paul F. Hoffman and Daniel P. Schrag
Half course (fall term). Hours to be arranged.
Theory and observations pertaining to the snowball earth hypothesis, including climate models, paleomagnetic constraints, sedimentological phenomena, geochemical perturbations, isotopic anomalies, and biological implications. Snowball events in Earth history and their spatial and temporal variability. Strengths and weaknesses of existing explanations, alternative hypotheses, and testable predictions. Evolution of the hypothesis and reactions to it, as an example of how scientists respond to radical ideas.
Prerequisite: One basic earth science course (e.g., EPS5, EPS6, EPS7, EPS8, Science A-24, Science A-30, Science A-37, Science B-16, Science B-34) or permission of the instructors.

Earth and Planetary Sciences 285r. Analytical Paleontology
Catalog Number: 2132
Charles R. Marshall
Half course (fall term). Hours to be arranged.
A general treatment of different approaches to designing and testing quantitative models in paleobiology. Topics include, but will not be restricted to: determining times of origin and extinction; dissecting diversity dynamics; assessing the absolute completeness of the fossil record; stratigraphy and phylogeny reconstruction.
