Because there aren't enough taxa to justify a dendrogram here, I have instead taken the liberty of copying Tom Holtz' excellent chronogram (mapping phylogeny against geological time) - original url GEOL 331 Invertebrate Paleontology, Lectures 35-36: Vertebrate Paleontology. This diagram is based on Sansom et al 2010 and, from the paraphyletic placoderms, Brazeau 2009. Here the Eugnathostomata at the bottom right is the same as our Teleostomi
