PGRs Amy Shipley (@sauropodlets.bsky.social) & Lydia Woods recently published a review in @globalchangebio.bsky.social showing that while today’s extinction rates aren't yet at "Big Five" mass extinction levels, they’re likely the highest seen in the last 66myrs.

10 years ago, our co-edited Topics in Geobiology volumes on #Ammonoid #Paleobiology came out:

From anatomy to ecology:
doi.org/10.1007/978-...
From macroevolution to paleogeography: doi.org/10.1007/978-...

In the last months of 2025, i will explore new discoveries on these topics in a thread:
Ammonoid Paleobiology: From anatomy to ecology
This two-volume work is a testament to the abiding interest and human fascination with ammonites. We offer a new model to explain the morphogenesis of septa and the shell, we explore their habitats by the content of stable isotopes in their shells, we discuss the origin and later evolution of this important clade, and we deliver hypotheses on its demise. The Ammonoidea produced a great number of species that can be used in biostratigraphy and possibly, this is the macrofossil group, which has been used the most for that purpose. Nevertheless, many aspects of their anatomy, mode of life, development or paleobiogeographic distribution are still poorly known. Themes treated are biostratigraphy, paleoecology, paleoenvironment, paleobiogeography, evolution, phylogeny, and ontogeny. Advances such as an explosion of new information about ammonites, new technologies such as isotopic analysis, tomography and virtual paleontology in general, as well as continuous discovery of newfossil finds have given us the opportunity to present a comprehensive and timely "state of the art" compilation. Moreover, it also points the way for future studies to further enhance our understanding of this endlessly fascinating group of organisms.
