"We now know that pterosaur crests had all kinds of combinations," Hone told Live Science. Some pterosaurs even appear to have had a saillike crest made up of a membrane sheet connecting two large bones on the head. One of the largest pterosaurs is believed to be Quetzalcoatlus northropi, whose wingspan reached 36 feet (11 m), according to the journal PLOS One.įor instance, some pterosaurs had big, bony crests, while other crests were fleshy with no underlying bone. This discovery, described in the journal Cretaceous Research, followed an examination of a fossil that had been in the Natural History Museum of London since 1884. This means that their wings would have had to generate enormous amounts of force to lift them from the water back into the sky.Īnother large pterosaur was Coloborhynchus capito, which had a wingspan of about 23 feet (7 m). These pterosaurs would have been rarely seen on land and potentially spent their time on the water when not in the air, according to the American Museum of natural History. It's thought that Pteranodon spent its time soaring over open ocean in the hunt for fish. It had a wingspan that ranged from 9 to 20 feet (2.7 to 6 m), according to Current Research in Earth Sciences, a peer-reviewed bulletin of the Kansas Geological Survey. Pteranodon, discovered in 1876 by Othniel C. The remains of this pterosaur were found in Scotland’s Isle of Skye an revela the reptile had a wingspan of more than 8 feet (2.5 meters), according to the journal Current Biology. The largest species that would have soared during the Jurassic period – 201.3 militon to 145 million years ago – was the Dearc sgiathanach. There was some confusion early on as to the size of the Pterodactylus, because some of the specimens turned out to be juveniles rather than adults. Pterodactylus antiquus (the only known species of the genus) was also a comparatively small pterosaur, with an estimated adult wingspan of about 3.5 feet (1.06 meters), according to the journal Paläontologische Zeitschrift. The remains of this flying reptile revealed that over half of the length of its wing was occupied by a long finger, which anchored the membrane that made up the wing to the body, according to the Carnegie Museum of Natural History. It had a wingspan of only 10 inches (25 centimeters), according to a description of the animal, published in the journal Proceedings of the National Academy of Sciences. The smallest pterosaur, called Nemicolopterus crypticus, was discovered in the western part of China's Liaoning Province. Once airborne, the largest pterosaurs ( Quetzalcoatlus northropi) could reach speeds of over 67 mph (108 kph) for a few minutes and then glide at cruising speeds of about 56 mph (90 kph), the study found. What's more, a study published in the journal PLOS One suggested pterosaurs had powerful flight muscles, which they could use to walk as quadrupeds (on all fours) like vampire bats and vault into the air. However, scientists later discovered that some pterosaurs, including Sordes pilosus and Jeholopterus ninchengensis, had furry coats consisting of hairlike filaments called pycnofibers, suggesting they were warm-blooded and generated their own body heat, according to the Chinese Science Bulletin.
