User blog:SilverTiger12/A Review of Dracoform Taxonomy

Note: This page is a work in process and is in no way, shape, or form complete or finalized. Significant changes may be made as new information comes to light.

The dragons and their kindred species are among the most innately magical and biologically complex creatures of the Material plane, but their reclusiveness and, in the case of many species, rarity, has prevented any major taxonomic work on the group. This article seeks to rectify that by examining the internal taxonomic relations of the dragonkind. Undead dragons are not treated here, as they are by their nature not independent species at all but non-living things created from the bodies of other species. This article also relies more on environmental, magical, and otherwise biological similarities and affinities than on any supposed lines of evolutionary descent for its organization.


 * See Hall 1983 ("Landragons" in Dragon #74) for early commentary on the taxonomic distance between Reptilia and Dracoformes. He notes that dragons form an isolated group that is only distantly related to reptiles, but only considers there to be two genera, Draco and Drogas.

Systemic Taxonomy
Kingdom: Animalia

Phylum: Chordata

Class: Dracoformes

Dracoformes is the class that encompasses all true dragons and a number of other, related species. Physiological characteristics apparently include warm-bloodedness (probably homeothermic), scaly skin, and oviparity, among others.

Side notes:
 * The greaters drakes, elemental drakes, and felldrakes all form monophyletic clades within themselves, but probably not with each other or even with other drakes. The word "drake", in fact, seems to be more of a catch-all term for anything small and draconic.
 * The cobra dragon is, at this time, believed to be a false dragon: a reptile of perhaps serpentine affilition, rather than a dracoform. It is suspected that various other dragons and dragonkin are also "merely" large, dangerous reptiles (or in at least one case, an avian).
