This is an intermediate level cladogram.  It shows taxa corresponding to abbreviated cladograms in each unit of Palæos: Vertebrates, plus a few others necessary to avoid showing spurious relationships. For the highest level of detail, see the individual unit cladograms, if any.

Taxa in BOLD CAPITAL LETTERS correspond to units in the main section.

X indicates an extinct taxon.
Quotation marks indicate either a paraphyletic group or an unpublished name.
