Oh - the first one is out! I’m editing several of these systematic reviews, and am looking forward to seeing all other contributions :)

My new paper with @gdarlim.bsky.social and @hoehna.bsky.social is now out in Proceedings B! We set out to compare two different approaches to time-calibrate a molecular phylogeny: traditional node calibrations, and unresolved FBD... @royalsocietypublishing.org

Very well-timed publication of my most recent work at @royalsociety.org Proc B showcasing the backbone of my future research at @stonybrooku.bsky.social!
There is still much to learn about ray-finned fish neurocranial evolution and the diversity of ways brain and endocasts interact in this lineage!
📢 Paper alert!
Excited to share the first publication of my PhD!😁
We analysed fossil occurrences of the last 23 Ma to understand how geographic range change relates to extinction risk.🌍🐚🪸🦈
Keen to learn more? Here is the paper:

Double satisfaction today: Important reptile phylo paper out, & my family & I reached Vienna - a cycle trip of more than 400km down the Danube fr where we started in 🇩🇪. In this stunning building (Natural History Museum), they house one of the coolest turtle fossils (Archelon) - just passing today.
The coolest paper I’ve been involved with in a while just dropped! 1. we have (plenty) morphological support for turtles+archosaurs. 2. Eunotosaurus is a millerettid stem reptile, no stem turtle. 3. Without clear fossorial precursors, the ecology of shell evolution needs to be revisited (aquatic!?)
My kids like the right kind of animals 🐢❤️
Good to see that this specimen will reside in Brazil in the (hopefully near) future.
Abstract. Time-calibrating a phylogenetic tree is a fundamental step in phylogenetic inference, as it allows the study of macroevolutionary processes such

New paper! Thanks to John for initiating & leading this work, in which we describe the collumellae/stapes of sauropsids, including turtles 🐢, birds 🐦⬛, lepidosaurs 🐍 and crocs 🐊.

Abstract. Vertebrates are unique among animals as they bear a neurocranium, which almost completely encapsulates the brain. Thus, within vertebrates, the e
Temnodontosaurus, a large ichthyosaur from the Early Jurassic, was one of the first ichthyosaurs to be scientifically described as early as the 19th century. Over time, various large Toarcian ichthyos...

The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparit....
The #fossil of Irritator challengeri is finally going back to Brazil after 35 years in Germany. This is a major event for #DecolonizeScience and the #restitution of natural history specimens.
Let's talk about #IrritatorBelongstoBR. [1/17]
