25 T148. Refining the Cambrian—Biotas, Multiproxy Correlations, Workable Global Divisions, and Paleogeography: Discussions in Honor of Fred Sundberg
Session Chairs:
Carol Dehler, Ed Landing, Mark Webster, Brian R. Pratt
Eumetazoan diversification and origin of relatively modern marine ecosystems make the Cambrian a key Phanerozoic interval. This session focuses on the correlation significance of improved chemostratigraphic, biostratigraphic, astrochronologic, atmospheric, and oceanic syntheses; geochronology; and new paleogeographic and paleoclimatologic work.
