    Ornithocheiromorpha - Wikipedia

    • Ornithocheiromorpha (from Ancient Greek, meaning "bird hand form") is a group of pterosaurs within the suborder Pterodactyloidea. Fossil remains of this group date back from the Early to Late Cretaceous periods (Valanginian to Turonian stages), around 140 to 92.5 million years ago. Ornithocheiromorphs have been discovered worldwide except Antarctica, though most … 展开

    History of research

    The first specimens of ornithocheiromorphs were unearthed at a chalk pit near Burham in Kent, England. In 1846, British paleontologist James Scott Bowerbank named and described the remains found as Pterodactylus giganteus, … 展开

    Description

    Ornithocheiromorphs were large pterosaurs, with wingspans normally ranging between 3 and 6 meters (9.8 and 19.7 ft). Istiodactylus for example, had a wingspan ranging from 4.3 to 5 meters (14 to 16 ft), with th… 展开

    Classification

    Several studies show that ornithocheiromorphs were less derived than the toothless pteranodontids such as Pteranodon, and based on the different evolutionary changes, they therefore need to be grouped in … 展开

    Paleobiology

    Ornithocheiromorphs were originally regarded as piscivorous creatures, feeding mainly on small and mid-sized fish. Some paleontologists even suggested details on how these pterosaurs caught fish, some of which included d… 展开
