Chordate Dendrogram (Dendrogram)

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 highest level of detail, see the individual unit dendrograms, if any.

Taxa in BOLD CAPITAL LETTERS correspond to units in the main section. MH is a link to the equivalent page of Mikko Haaramo's phylogeny archive (note: these links no longer work, but have not been updated as yet. When they are updated, this message will be removed. - MAK). 
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Quotation marks indicate either a paraphyletic group or an unpublished name.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)
