Istiodactylus

---

It took more than a century for Istiodactylus to be untangled from a naming controversy (long story short, this mid-sized pterosaur was initially classified as a species of Ornithodesmus, until Ornithodesmus was itself downgraded because some of its bones turned out to belong to a terrestrial theropod, i.e. carnivorous dinosaur). Assigned to its own genus in 2001, Istiodactylus appears to have been an average pterosaur of the early Cretaceous period, closely related to the South American Anhanguera.
