Many animals can reshape and shed their teeth – and now scientists have traced this ability back 380 million years

A new study of ancient, extinct fish known as placoderms provides another piece of the evolutionary puzzle about our deep time, aquatic ancestors.

A 380‑million‑year old predatory fish from Central Australia is finally named after decades of digging

For decades, the sandstone in central Australia yielded tantalising segments of some sort of fossil fish. Now, we have finally pieced together a complete picture of this remarkable species.

Un fossile vieux de 380 millions d'années révèle l'origine de nos mains

Une espèce qui a vécu il y a 380 millions d'années révèle l'origine de nos mains. Il est le plus proche de ce que l’on pourrait considérer comme un « chaînon manquant ».

L’étrange cœlacanthe passé aux rayons X

Espèce menacée vivant dans les profondeurs marines, le cœlacanthe passionne depuis sa découverte en 1938.

We scanned one of our closest cousins, the coelacanth, to learn how its brain grows

The discovery of a living coelacanth fish rocked the world in 1939, as scientists thought they had died out with the dinosaurs. A new study illuminates how its skull and tiny brain develop.

Ancient fish evolved in shallow seas – the very places humans threaten today

New research shows shallow, near-land seas similar to Bass Strait were critical in the early days of fish evolution. These are the waters we need to protect now to ensure ongoing biodiversity.
