Ikrandraco - Facts and Figures

Name Ikdrandraco (Ikran dragon, after the flying creatures from Avatar); pronounced EE-krahn-DRAY-coe Habitat Rivers and lakes of Asia Historical Period Early Cretaceous (120 million years ago) Size and Weight About 30 inches long and a few pounds Diet Fish Distinguishing Characteristics Moderate size; distinctive bill structure; possible throat patch for holding fish About Ikrandraco Ikrandraco is an odd choice to honor the Ikran, or mountain banshees, of Avatar: this early Cretaceous pterosaur was only about two and a half feet long and a few pounds, whereas the Ikran from the hit movie are majestic, horse-sized, flying creatures that the Navi ride into battle against their human antagonists. Once you get past its name, though, Ikrandraco avatar may have been a truly unique pterosaur: some paleontologists claim that it had a pouch on the underside of its distinctively shaped bill in which it stored recently caught fish, which would make it similar to the modern pelican. However, not everyone is convinced by this putative anatomical feature of Ikrandraco (made of soft tissue, a throat pouch would have no chance of surviving in the fossil record), nor by the hypothesis that this pterosaur skimmed over the surface of lakes and trapped wiggling prey in its submerged lower jaw. The fact is that it can be difficult to infer the everyday behavior of a 120-million-year-old reptile by analogy with modern birds, and the possibility remains that Ikrandraco fed in more conventional fashion, like other pterosaurs of the early Cretaceous period, simply diving into the water and swallowing its fill of fish.
