This is an intermediate level dendrogram ("cladogram").  It shows taxa corresponding to abbreviated dendrograms in each unit of Palaeos: Vertebrates, plus a few others necessary to avoid showing spurious relationships. For the basic overview, see the summary dendrogram. For the highest level of detail, see the individual unit dendrograms, if any.

Taxa in BOLD CAPITAL LETTERScorrespond to units in the main section. MH is a link to the equivalent page of Mikko Haaramo's phylogeny archive 
ToL is a link to the equivalent page of the Tree of Life.
X indicates an extinct taxon.
Quotation marks indicate either a paraphyletic group or an unpublished name. ATW

Note also that the dendrogram given here may not match revisions in the Palaeos unit pages. As always, Palaeos is a work in progress - MAK)
