The 26 chapters of this symposium volume encompass reviews of special topics, summaries of particular datasets and original research contributions. Together they span age intervals ranging from the Neoproterozoic, Mesozoic to Paleogene and Recent addressing a variety of stratigraphic, paleoecologic, environmental and paleoclimatic events. These contributions are organized under four themes: 1. Applications, 2. Paleoecology—Recent, 3. Global bioevents—PE and KTB, and 4. Biodiversity and Stratigraphy in Deep Time.
