My new ANR project has officially started yesterday! #MECHAMORPH will unravel some secrets of the evolutionary success of #snakes! We will look at head and skull shapes and their multiple functions using an interdisciplinary approach. Stay tuned! Special thank to my brother for his killer logo 💚🐍

#Communiqué 🗞️ Longtemps considérés comme exclusivement marins, les mosasaures comptaient aussi des espèces d’eau douce. Un spécimen de 2,5 m, vieux de 85 millions d’années, retrouvé dans un lac, en apporte la preuve. 👉 www.cnrs.fr/fr/presse/un...

Nouvel article par Erik A. Meilak @University of Southampton avec @paulineprovini.bsky.social #MECADEV sur la fameuse question de l'envol d'Archaeopteryx.
Archaeopteryx BOUNCED into the air! Our new paper in @devbiol.bsky.social shows the first bird used multiple leaps (like modern crows) to take off, using today’s birds to unlock how flight evolved 150M years ago! 🔗Read more here: www.sciencedirect.com/science/arti... #DinosaurBird #HowFlightBegan

Happy to share this 'capstone' project from my time as a postdoc @umich.edu, where we show that hierarchically nested bursts of body-shape evolution may underlie much of perching-bird diversification over ~50 million years. Free access link here: rdcu.be/fuxB1

Happy to announce that our latest study with @houssayecnrs.bsky.social is now published in the @anatrecord.bsky.social. 🐧🦆🪿 doi.org/10.1002/ar.7... How does the inner structure of the limb bones of aquatic birds relate to their locomotor abilities? 🦴
Through geometric morphometrics and R-based modeling, this tool enables the adjustment of morphospace parameters to simulate shape transitions. Working in progess
The rphylopic package allows users to add silhouettes of organisms from the PhyloPic database to plots generated in base R and ggplot2.
Very happy to present a poster this evening at @sebiology.bsky.social conference in Florence! I will be talking about preliminary results on the role of larynx and hyoid in birds vocal complexity, as part of my PhD work. 🦜🎶
