List of indeterminate prehistoric percomorph genera

In the past, many fossil fish genera from the Late Cretaceous onwards were placed in the order Perciformes or the suborder Percoidei. Recent taxonomic revisions have found the former interpretation of Perciformes and Percoidei to be paraphyletic, comprising many distantly related families from across the Percomorpha, and these studies have thus significantly restricted the new definition of Perciformes.[1] As these revisions were based primarily on genetic data, the taxonomic affiliation of many of these fossil "perciforms" is now uncertain beyond them belonging to the Percomorpha.[2] This list contains fossil genera that are either considered indeterminate percomorphs or were previously assigned to the sensu lato interpretation of Perciformes/Percoidei:
