When did Perciformes evolve?
The answer, it seems, is that these groups were already in place by the early Tertiary [50 million years (Ma) ago], with origins spreading back to at least the late Cretaceous (70 Ma), and possibly even to the early Cretaceous (100–130 Ma). Most reef fish families have been placed in the order Perciformes.
