The study of ancient ecosystems is critical to our understanding The objective of this session is to highlight the advances made
of the present. Paleoecological studies of broad relevance to in recent years in fossil phylogenetics and to discuss the difficul-
understanding biotic responses to environmental and climate ties and successes in overcoming implementation of deep-time
changes are explicitly discussed. phylogenies in new statistical methods.
