STRESS—Highlights in Ammonite Research: Stratigraphy, Taphonomy, Resources, Ecology, Stable Isotopes, and Sedimentary Geology in Focus

Dear Colleagues,

Ammonoidea is one of the most important fossil groups to understand the geologic past: recent proceedings in ecology, biogeography, stratigraphy, paleoenvironment, climate, etc. cannot contribute efficiently to science without new, thought-provoking, or unusual approaches to Ammonoidea. Therefore, we gave an unusual title to this Topic: “Ammonoidea under STRESS”, where STRESS is an initialism derived from the initials of stratigraphy, taphonomy, resources, ecology, stable isotopes, and sedimentary geology.

We highly encourage you to contribute to this Topic with new data, ideas, information, theories, research, or experiments that are not in the mainstream of ammonite research, therefore providing an interesting, appealing Topic to collect the knowledge on the frontiers (or neglected fields) of ammonite science. Our aim is to focus on intriguing, debated, and antinomic theories, results, and data regarding ammonite research and new initiatives, whether it regards the lifespan of Ammonoidea (stratigraphy), their marks in the former environment (taphonomy), their needs, habitats, diet, evolution, and extinction (resources and ecology), or their usefulness in stable isotope studies and special relationships to sedimentary geological processes. We highly encourage you to consider publishing your original and thought-provoking results related to these aspects of Ammonoidea.

This Topic is organized into five sections:

• Section 1 Stratigraphy;
• Section 2 Taphonomy;
• Section 3 Resources and Ecology;
• Section 4 Stable Isotopes;
• Section 5 Sedimentary Geology.

This Topic aims to contribute to the understanding of the role, usefulness, applicability, processes, and interrelationships of a leading fossil group, the Ammonoidea.
