"Traditionally, they [pterosaurs] are organized into two suborders:
  • Rhamphorhynchoidea (Plieninger, 1901): A group of early, basal ("primitive") pterosaurs, many of which had long tails and short metacarpal bones in the wing. They were small, and their fingers were still adapted to climbing[citation needed]. They appeared in the Late Triassic period, and lasted until the late Jurassic. Rhamphorhynchoidea is a paraphyletic group (since the pterodactyloids evolved directly from them and not from a common ancestor), so with the increasing use of cladistics it has fallen out of favor in most technical literature.


Long tail and teeth.

Shortened tail and lack of teeth.

Modern bird (for example the albatross).

  1. The stork bears a remarkable resemblance to the pterodactyl pictured above. SeeüeñaenÁvila.jpg

    The stork has even been mistaken as a modern-day pterodactyl: "A series of sightings of a mysterious pterodactyl-like creature in South Texas' Rio Grande Valley in the 1970s has been attributed to an errant jabiru that became lost during a migratory flight and wound up in an unfamiliar region, or an Ephippiorhynchus stork escaped from captivity."
