291 Cephalopods Through Time: Insights into Evolution, Ecology, and Environmental Reconstruction

This session explores cephalopod biology, ecology, and evolution, highlighting their role in paleoenvironmental reconstruction. We welcome analytical and computational research that advances understanding of these organisms, providing new perspectives on their evolution and ecological significance.
