If you ride in a hot air balloon today, your max altitude is only around 2, feet. When skydiving, your exit altitude is always under 15, feet because to skydive from that altitude would require more oxygen. With such phenomenal flying abilities, the pterodactyl must have been quite the agile flier, right?
Indeed, it was! Experts believe that part of that had to do with its wing shape, which this report from the journal Proceedings of the Royal Society B discussed. Check out the Ultimate Guide see description and link directly below or other key Series Articles selected for you at the bottom of this article! This is the main article in the series and it is packed with information all about the flying reptiles that ruled the skies during the Mesozoic Era. It covers the different types of pterosaurs, from the basal pterosaurs and later species as well.
There are sections on pterodactyl anatomy, classification, and phylogeny. The master article also covers: —Interesting facts you may not know about pterosaurs —Tables comparing wingspan sizes of different pterosaur species —Links to all the Series Articles 11 in total! We had to start, of course, with the pterodactyl or Pterodactylus.
Although some experts have argued that the pterodactyl was rather big, possibly even too large to fly, as an adult animal, the pterodactyl would have had a wingspan of only 3 feet, 5 inches, or 1. That suggests this was a smaller creature.
Eudimorphodon was a pterosaur that lived in the Late Triassic Period and was found in areas of what is now Italy. Weighing around 22 pounds, the Eudimorphodon also had an oversized fourth finger in which its membrane formed a wing. It possessed more teeth than the pterodactyl, though, versus The Vectidraco had a small wingspan like the pterodactyl and Eudimorphodon, with its wings opening 75 centimeters. Known as the Phobetor, the Noripterus was a dsungaripterid pterodactyloid pterosaur.
For the study, and with the help of Kevin Padian from the University of California, Berkeley, Manafzadeh took some quail hip joints, cut the surrounding muscle, and manipulated the joints while recording x-ray videos. The bones alone approach, this experiment showed, is both inadequate and inaccurate.
Nearly 95 percent of the poses that seemed plausible with the bones alone approach were found to be physically impossible when the ligaments were attached. This included the swinging of the hips outward in a bat-like way. For the second stage of the study, the researchers sought to compare the range of motion in present-day quail hips with the expected range of motion in extinct flying reptiles. They found that in quails, the outward motion of the thigh bone was inhibited by a particular ligament—one found in a wide variety of modern birds.
The new study now casts doubt on many reconstructions of flight posture, and it could influence the way paleontologists study joint mobility and movement in other extinct animals, including terrestrial creatures. It will be exciting to see the future integration of this important development with fossil soft tissue discoveries. Pittman, who studies the four-winged dinosaur, says this finding could impact his own work.
Until we know more about the soft tissue of extinct creatures, paleontologists will continue to approximate bodily form and function. Palaeontologists still have many questions about giant pterosaur flight. Did they flap or soar? How long could they fly for? How did they land? In fact, some people still believe these giraffe-sized animals were too heavy to fly at all.
But then what did they do with their wings? These are all questions that new techniques and fossil finds are starting to answer.
