How did the Quetzalcoatlus Northropi fly?
Pterosaurs flew with their forelimbs. As pterosaurs’ arm and hand bones evolved for flying, they lengthened, and the bones of one finger—the equivalent of our ring finger—became extraordinarily long. Like the mast on a ship, these bones supported the wing surface, a thin flap of skin that was shaped like a sail.
How did very large pterosaurs like Quetzalcoatlus become airborne?
The researcher says his new study reveals the first line of evidence that pterosaurs launched into the air using four limbs: two were ultra-strong wings which, when folded and balanced on a knuckle, served as front “legs” that helped the creature to walk and leap sky-high.
How can a pterosaur fly and maintain lift with such a massive body?
Membrane wings, such as those of pterosaurs and bats, produce more lift per unit speed and area than the feathered wings of birds. This additional lift improves slow-speed maneuvering capability, which for small animals helps with making tighter turns and for big animals facilitates takeoff and landing.
How did giant pterosaurs fly?
After analyzing the biomechanics of the creatures, Habib proposes that pterosaurs took flight by using all four limbs to make a standing jump into the sky, not by running on their two hind limbs or jumping off a height, as more widely assumed. “I started as a bird researcher,” Habib says.
How did pterosaurs go extinct?
At the end of the Cretaceous period 65 million years ago, a meteorite or comet slammed into Earth. That calamity—and other events—wiped out roughly three-quarters of all animal species, including all remaining pterosaurs and dinosaurs.
What did the Quetzalcoatlus do?
Quetzalcoatlus dominated the skies of North America at the end of the Dinosaur Age and flew high over such famous creatures as Tyrannosaurus and Triceratops. As tall as a giraffe, the biggest Quetzalcoatlus species were also the largest of all flying creatures. They were the ultimate in pterosaur evolution.
How did the Quetzalcoatlus go extinct?
Quetzalcoatlus lived during the late Cretaceous period and died out about 65 million years ago, during the K-T mass extinction. Quetzalcoatlus was a carnivore, probably skimming the water to find prey. It probably hunted its prey by gliding toward the water and swooping up its meals.
What is Quetzalcoatlus in on the wing?
Quetzalcoatlus was the star of the 1986 IMAX movie On the Wing where a half-sized robot version engineered by AeroVironment demonstrated primitive flight. It appears in the nature documentary Walking with Dinosaurs episode “Death of a Dynasty”, but is one of the most inaccurate creatures in it, mostly because it is an edit of Ornithocheirus.
Was Quetzalcoatlus the biggest flying creature that ever lived?
A close-up of the Pterosaur’s head and toothless beak. Quetzalcoatlus was the biggest flying creature that ever lived (second biggest if Hatzegopteryx is in fact bigger than Quetzalcoatlus).
How big was the model of Quetzalcoatlus?
It was about half scale (20 ft), the size of Quetzalcoatlus sp., and had a simple computer functioning as an autopilot. The experiment worked and the model flew through the skies with a combination of soaring and wing flapping.
Is this azhdarchid neck vertebrae from Quetzalcoatlus?
An azhdarchid neck vertebra, discovered in 2002 from the Maastrichtian age Hell Creek Formation, may also belong to Quetzalcoatlus. The specimen (BMR P2002.2) was recovered accidentally when it was included in a field jacket prepared to transport part of a tyrannosaur specimen.
