The earliest fish with dedicated respiratory gills and [[paired fins]], the [[ostracoderm]]s, had heavy [[armour (anatomy)|bony plates]] that served as protective [[exoskeleton]]s against [[invertebrate]] [[predator]]s. The first fish with [[jaw]]s, the placoderms, appeared in the [[Silurian]] and greatly diversified during the [[Devonian]], the "Age of Fishes".
