Happy to share our new paper published in Proceedings B! led by @acapomorphic and @SebastianHoehna “How to date a molecular phylogeny: comparison of effective priors between node calibration and fossilized birth–death” @RSocPublishing 🔗 doi.org/10.1098/rspb.2025.32…

We also show the impact of the number of fossils included in the unresolved FBD analysis on node ages. To have effective priors that are more informative than those induced by flat node calibrations it’s necessary a substantial number of fossils (in our croc example, >20).

To time-calibrate a molecular phylogeny, we recommend using the unresolved FBD approach when several extinct species are sampled in your group of study. Conversely, for groups with only a few fossils available, we favour the use of classic node-dating approaches.

As of last month, I’ve joined the editorial board of the Journal of Vertebrate Paleontology (@JVP_vertpaleo) as the new Phylogenetics Editor! I’m responsible for evaluating reproducibility of phylogenetic analyses submitted to the journal. 💻⚒️

🚨 Out today: our Editorial in the Journal of Vertebrate Paleontology on an important issue in science - the reproducibility crisis in phylogenetic analyses. In it, we analyze several years of editorial data to ask a simple question: are things improving? tandfonline.com/doi/full/10.…

Our new giant ZJLS paper on the Wealden croc Koumpiodontosuchus is out, and thus.... tetzoo.com/blog/2026/4/13/ko… A great study led by Chris Barker and @EvoPalaeoLab (art here by Mark Witton). #crocodylomorphs #Cretaceous #Wealden #fossils

A little late, but we are excited to introduce a new Triassic crocodylomorph! Eosphorosuchus lacrimosa is a short snouted, contemporary of Hesperosuchus with a powerful bite. The work was led by my Colleague Miranda Margulis Ohnuma. Link to paper below. Art by Julio Lacerda

The last chapter of my PhD thesis has been finally published! We describe the axial skeleton of the Tuatara in detail, focusing on osteological variability, ontogeny, and fossil remarks. Check it out, it's open access! academic.oup.com/zoolinnean/…

🚨 New paper I had the honor to illustrate! 🚨 Guilherme Hermanson and Serjoscha W. Evers take a look at the survivors of the K-Pg event among the turtles and besides size note that especially diet is something that sets them apart: many of them very shell crusher! paper below:

For this #FossilFriday, I'm happy to share our new study "Practical Guide and Review of Fossil Tip-Dating in Phylogenetics" now open access in Systematic Biology 🔗doi.org/10.1093/sysbio/syaf0… 🦖🦈🐊🐞 Amazing work by @acapomorphic, @basantakhakurel, @heckeberg and @SebastianHoehna

In this paper, we provide the state-of-the-art by surveying all empirical tip-dating studies - until 2023 - , explain key concepts and provide general recommendations for all the components underlying fossil tip-dating phylogenetic analysis

From data collection to model selection - including a nice and colorful flowchart to guide the reader - we hope that our study assists researchers on performing their own fossil tip-dating analysis
