139 T155. Evolution of Life in the Cambrian Seas: Biotic, Biogeochemical, and Sedimentological Contexts, Part II


Session Chairs:
Rudy Lerosey-Aubril, Robert R. Gaines, Javier Ortega-Hernandez, Lidya Tarhan

This session is dedicated to studies that illuminate the biotic, geobiological, sedimentological, and geochemical contexts of the evolution of early animal life in the oceans, with a particular focus on the Cambrian Period.
