Acrolepididae Explained

Acrolepididae is an extinct family of ray-finned fish.^[1] Genera referred to Acrolepididae existed from the Early Carboniferous period to the Early Triassic epoch. They were nektonic carnivores with a fusiform body.

Acrolepididae may be closely related with the Early Mesozoic Ptycholepididae.^[2]
