Thursday, 26 December 2013
Originally described by Seeley in 1901 and thought to be a bird, Istiodactylus has been recognized as a pterosaur and changed its name from Ornithodesmus because the original material used for the description also contained some theropod dinosaur bones. Istiodactylus lived during the Early Cretaceous of what is now England. It had a flat rounded shape beak with an unusually large naso-antorbital fenestra which is occupying most of the snout. Istiodactylus and its relatives could had lived on a diet of fish; however, given the general distribution of istiodactylids, they would have to be inland piscivores rather like modern pelicans. There have also been some proposition that they were actually scavengers, as they were more efficient walkers than other ornithocheiroids and had teeth similar to those of some sharks.
