Description
A quick graphic illustrating the evolution of dragons in a way you might find it in a school book, of course oversimplified and rough.
The first years of the draconiformes are still somewhat mysterious as well as the phylogenetic relationships of the Varanoidea overall.
Shown here are, from top to bottom: snakes, gila monsters, sea serpents, mosasaurs, dolichosaurs, earless monitors, Appotomerus, monitor lizards, dragons. In addition you see there a Ovoo gurval, probably the oldest varanid, and Kaganaias, a small, very basal varanoid from Japan.

Since you mentioned, that dragons are endotherms (warm-blooded) and are relatives of monitor lizards, which are ectothermic (cold-blooded). I am just curious, how did it evolve?
