The origin of pterosaurs is one of the needless mysteries of paleontology. The problem was solved in 2000, but other pterosaur workers have chosen to ignore the published literature in favor of antiquated and irrational paradigms. For reasons known only to themselves, they prefer to keep the origin of pterosaurs a mystery.
Here are the best known taxa in the lineage of pterosaurs along with a gradual accumulation of pterosaur traits for each taxon. Among 572 tested specimens, none are closer in terms of morphology. An extended cladogram is presented along with several reconstructions of pertinent specimens. Comparisons are made to various competing candidates. The evolution of several body parts is presented.
It is noteworthy that some of the reptiles closest to pterosaurs had stunted forelimbs/tiny wings. This is not unexpected as several birds likewise have and had stunted wings.
