An international symposium is coming next year: 18th International Symposium on Early and Lower Vertebrates #paleontology 🦈🐟 📅 February 3-8, 2026 📍 Berrechid, Morocco ➡️ sites.google.com/view/iselv-1...

Glad to share a new paper led by @yara_haridy and @NeilShubin Lab on the early evolution of teeth! Modern and fossil data point at an ancestrally sensorial function for the earliest dentine www.nature.com/articles/s41...

Wonderful power of exaptation! Sensory organs to feeding structures and weapons in vertebrates: "patterns of convergence and innervation reveal that dentine evolved as a sensory tissue in the exoskeleton of early vertebrates" www.nature.com/articles/s41... 🧪 ⚒️ #Paleobio #EvoBio #Geology

Thrilled to have co-written a News & Views with P. Janvier on Haridy et al.’s recent Nature paper. They reveal that Anatolepis, once thought to have the oldest dental tissue, is actually Cambrian arthropod sensory armor! Paper: nature.com/articles/s41... N&V: www.nature.com/articles/d41...

Congrats to Yara and team! They reveal that Anatolepis - previously interpreted as the oldest vertebrate with a mineralised skeleton - is not a vertebrate at all! Paper here: tinyurl.com/59sdw7x9 and a nice write up by @guillaumehouee.bsky.social & Philippe Janvier here: tinyurl.com/2u6haac8

New paper alert! This was a fun study examining intraskeletal growth patterns in leopard geckos using fluorescent labeling. Labels administered in ovo are still present up to 4 years post-hatching! doi.org/10.1111/joa....

1/10 🚨🚨 New paper with @tjnear.bsky.social! Here, we revise the systematics of sturgeons using a phylogenetic approach! We confirm an Early Cretaceous origin for the sturgeon total clade and resurrect several genera for living species!

Ok first post here! Hi, I study fossil snakes 🐍 and also produce paleoart!... sometimes... 👀

I am beyond honored to announce that our paper (academic.oup.com/evolut/artic...) revealing a molecular mechanism of evolutionary stasis has won the @sse-evolution.bsky.social President's Award This work would have been impossible w/o my colleagues @tjnear.bsky.social lab and beyond!

PhD alert: Je cherche un candidat pour travailler sur l'évolution morphologique et fonctionnelle de la tête des squamates apodes.

I'm excited to finally share our review on the evolution of enameloids and enamels, now published in Biological Reviews! onlinelibrary.wiley.com/doi/epdf/10....

Having studied the paleodevelopment of early dental structures during my PhD, I'm excited to now be working as a postdoc on the origin of hypsodonty in Equidae! #palaeotheres #enamel #histology
