Postdoc researcher 🇫🇷 at @mnhn.fr Origin & evolution of the vertebrate mineralized skeleton 🦷🦴 Histology, Microanatomy, Modeling development https://www.researchgate.net/profile/Guillaume-Houee

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...

The evolutionary origin of sensitive dental structures

Fossil data shed light on a debate about when vertebrate dental tissues arose by assigning an early sensory structure to arthropods rather than to vertebrates.

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
