Key adaptations

Pteraspis had a protective armour covering its head and the front of its body, and spines on its back thought to be for defence against predators. Although lacking fins, it had wing-like protrusions from its body armour.

Did you know that...?

The name Pterapsis means 'wing shield', which refers to the wing-like protrusions from its body armour instead of fins.
