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.

Another years-long project I was a working group co-leader was published today as well!

Me, @lepidodendron.bsky.social and @rachelwarnock.bsky.social co-led the phylogenetics group and I had such a formative experience! ⚒️

When does biology become geology? This is a fun paper for us (although I, myself, was just one more member of Band-Aid for this particular paper), and hopefully it helps clarify a lot of things that we sort of already knew but never really formally addressed.

"Women climate scientists are connected, productive, and successful but have shorter careers"
Accessible, though paywalled at doi.org/10.1073/pnas...
🧪
Women may be discouraged from becoming climate scientists if they perceive the field as male-biased, but little is known about gender in climate science. An analysis of over 400,000 publications shows that men and women in climate science have similar degrees of productivity, success, and connectedness with other scientists, and publish in high-prestige journals at similar rates. However, the analysis also shows that women have marginally shorter careers, which leads to cumulatively fewer publications. Scholars have long been concerned about gender representation in scientific research but there has been little work on gender differences in participation and performance in climate science, a field that engages with both male-majority disciplines (e.g., geosciences, engineering) and female-majority disciplines (e.g., life sciences, medical science). This has implications for both gender equity and viewpoint representation. Sampling over 400,000 publications and a similar number of authors, we examine gender differences in several scholarly outcomes including publication count, career survival, coauthor gender, journal status, and mean citation count. We find men and women are similarly productive, successful, and connected, though women have shorter research careers and thus fewer papers. We also find gender homophily effects in collaboration, but no evidence of gender bias in peer review.
