Telencephalic eversion in embryos and early larvae of four teleost species

Evolution &Development, Volume 26, Issue 2, March 2024.
The telencephalon of ray‐finned fishes undergoes eversion, not evagination as in the rest of vertebrates. We show that the formation of the ventricle followed by a rostro‐caudal telencephalic expansion is key for the formation of an everted telencephalon in teleosts.

Los dipnoos (Sarcopterygii, Osteichthyes) del Mesozoico de Argentina

, 2023
Los dipnoos conforman un clado dentro de los sarcopterigios con un registro fósil que abarca desde el Devónico Temprano hasta el presente. Durante el Paleozoico los dipnoos eran mayormente marinos y su distribución cosmopolita. Sin embargo, a partir del Mesozoico habitan únicamente cuerpos de aguas continentales y su distribución comienza a limitarse ...

A Late Devonian coelacanth reconfigures actinistian phylogeny, disparity, and evolutionary dynamics

Nature Communications
The living coelacanth Latimeria (Sarcopterygii: Actinistia) is an iconic, so-called ‘living fossil’ within one of the most apparently morphologically conservative vertebrate groups.
