n fossil record, we would expect to find species with a nomocercal tail before (i.e., earlier than) species with a heterocercal tail. The sister group of Acipenseridae is Salmoniformes. Acipenseridae, Salmoniformes, Centrarchidae, and Scombridae form a clade. A group consisting of Acipenseridae, Salmoniformes, and Centrarchidae would be paraphyletic.
