Cheirolepis bench in "Animals Armageddon"
Cheirolepis ('hand fin') is an extinct genus of ray-finned fish that lived in the Devonian period of Europe and North America. It was among the most basal of the Devonian actinopterygians and is considered the first to possess the "standard" dermal cranial bones seen in later actinopterygians.
Cheirolepis was a predatory fish about 55 centimetres (22 in) long who lives on bench (like mackerel nowadays) feeding on smaller fish and crustaceans. But he is also a prey for the big fish of his time.
Cheirolepis benches are seen in the devonian ocean (while they actually live in freshwater) in the "Animals Armageddon" series.
