Synopsis

420 million years ago, some fish evolved armor made of plates and interlocking scales, which may have served purposes beyond protection.

Synopsis

420 million years ago, some fish species, such as Dunkleosteus, exhibited unique armor made of large plates and interlocking scales. This protective feature, often associated with defense against predators, may have also played a crucial role in their feeding strategies and environmental interactions. The evolution of these armored fish provides insights into the early development of vertebrate anatomy and the ecological dynamics of the Late Devonian period, a time marked by significant marine biodiversity and evolutionary advancements.
