A newly discovered fossil "treasure hoard" dating back some 436 million years to the early Silurian period reveals, for the first time, the complete body shape and form of some of the first jawed ...

The group of early jawed fishes traditionally referred to the Acanthodii is emerging as pivotal in our understanding of our own beginnings. The oldest history of these animals is poorly known, mostly ...
