Fengshen pterodactyl (scientific name: Fengshen pterodactyl) is an animal of Fengshen pterodactyl, which is distributed near the inland waterway in western North America.

Fengshen pterodactyl lived in the late Cretaceous, with a wingspan over 1 1 m and a streamlined body. It is the largest flying animal known to man. The nostril is above the head, close to the eyes below the spine, so that it can continue to breathe when eating; The mouth is long and thin, and there are no teeth inside; The front end of the beak is not sharp, but blunt, and the preorbital foramen is huge.

There are several theories about the feeding habits of Fengshen pterodactyl. Some experts believe that they trudged or floated in the diving area, filled their mouths and filtered out the water. The nostril is above the head, close to the eyes below the spine, so that it can continue to breathe when eating. Another view is that it is an omnivore. It may use its long beak to find shellfish food in the mud, or it may float in the vast sky like an albatross now. Gliding ability depends on a feature called wind load, that is, the ratio of animal wing area to its weight. Fengshen Pterosaur's wing area is equivalent to a small plane, but it may not be as heavy as a human because of its hollow skeleton and slender trunk. The best glider in modern times is designed to advance 4 meters per 1 meter, and the giant pterosaur may be much better than it. Moreover, Fengshen pterosaurs also have the ability to slow down and slowly descend, and they can also get updraft and quickly rush into the sky.

Fengshen Pterosaur will actively look for all the updrafts nearby, and the easiest thing to get is the updraft on the hillside or steep cliff. When the wind blows over the hillside, the wind will bend upward on the windward slope, producing a vertical wind speed component, which is the updraft on the slope. As long as the wind doesn't stop, there will be updraft on the hillside (people didn't know how to use this updraft until Li Lindal glided in 189 1). When the sun shines on the ground, beaches, cultivated land and sunny hillsides can also form updraft, which is called thermal updraft. Cumulus clouds are the "hat" of updraft and the "gas station" of long-distance gliding. Therefore, Fengshen pterosaurs may fly with cumulus clouds all day, and then rise to a height of 5 kilometers, at which they can fly more than 50 kilometers without flapping their wings.

Even if the skeleton is on the water, an experienced glider can use the aerodynamic force on the waves and keep flying with a little effort. On the windward side of the wave, it can obtain the rising force and keep flying at ultra-low altitude, thus making use of the "ground effect". The so-called ground effect is that the downwash of the lifting surface of the flying object (usually the wing, the wing) is blocked by the interference of the water surface, so that the air flow between the ground or the water surface and the lifting surface of the aircraft is compressed, that is, the pressure under the wing is increased, thereby increasing the lift of the wing and reducing the drag. Simply put, Fengshen Pterosaur has an air cushion under it, which is helpful for long-distance flight or ascent.

Similarly, Fengshen pterodactyl can also take advantage of the wind speed gradient in the ocean. There is friction between wind and water, which means that the closer to the water surface, the slower the wind speed. Fengshen Pterosaur flying close to the water surface can rise into the faster airflow, and the increased lifting force will push it to a higher place until it loses power. Then, it glides down at an angle to the wind direction, accelerates and is ready to repeat the whole process.

It has been suggested that the take-off and landing of Fengshen pterosaurs may be a problem, and they should jump up from the cliff and start flying. However, with the rising force generated by their huge wings, the breeze is enough to make them take off.

Fengshen pterodactyl has many different views on the lifestyle of Fengshen pterodactyl. Because it has a long neck spine and a long toothless jaw, it may prey on fish in a way similar to herons, vultures or modern seagulls. Fengshen Pterosaur should take off on its own, but once in the air, it may need to spend most of its time gliding. On the ground, Fengshen pterodactyl may walk on all fours.

The upper limit of the wingspan of Fengshen pterodactyl is still controversial. The largest fossil on display at the Minnesota Museum of Science may show that their wingspan is 18 meters (59 feet) long, but there are some uncertainties. This span may violate the basic structural upper limit of biological flight; Based on this statement, some scientists believe that the wingspan is as long as 12 meters (40 feet). The individual wingspan of the largest toothless pterodactyl was 9 meters (30 feet), which was considered as the upper limit of biological flight before the discovery of Fengshen pterodactyl.

Fengshen pterosaur died out with dinosaurs in the Cretaceous-Tertiary extinction event. The largest flying animal on earth has become extinct.

Fengshen pterodactyl has a wingspan of 1 1 m long and weighs 500 kg. It is the largest flying animal known to man. Fengshen pterodactyl has a fast metabolism and needs to eat regularly. Fengshen pterodactyl was streamlined and needed a lot of protein as energy. A golden baby Tyrannosaurus rex weighing less than 300 is regarded as a delicacy by it. Fengshen pterodactyl has huge wings, which makes it very suitable for long-distance gliding.

The individual skull of Fengshen Pterosaur is 1 m long and its wingspan is 5.5 meters. An adult's skull has not been found. According to the wing bone fragments, the wingspan is at least 10~ 1 1 m, which is the largest flying animal in the history of life on earth! Fengshen pterodactyl had a long and thin mouth and no teeth. The tip of the beak is not sharp, but blunt; Its preorbital foramen (located in front of the orbit) is huge, accounting for almost half of the total length of the skull, which undoubtedly reduces the weight of its big head; Fengshen wing faucet has a ridge crown, which is located in the front and upper part of the track, which is different from other pterosaurs of this genus.
