During the Cretaceous period, the largest flying reptiles lived – the Pterosaurians. From this category was also the flying Pteranodon flying dinosaur, which was of large size, never been touched by a flying animal.
According to paleontologists, the wings had a 7-8m and a weight of 15kg. Body weight was greatly diminished by having bare bones on the inside. This prehistoric creature lived in the Mesozoic era, in the Upper Cretaceous, about 70 million years ago.
Fossil remains of this species have been discovered in Oregon, Kansas, South Dakota, Wyoming, in Japan and England. On their basis, several species of this genus were classified: Pteranodon longiceps, Pteranodon ingens, Pteranodon marshi, Pteranodon sternbergi.
The most interesting part of this flying reptile was the very large head that had a 1.2-meter-long bone crest that had an important role in the steer, in the stabilization of the position during the flight, in the rapid change of direction when it was wanted.
This crest was always higher in males than in females, and in young specimens was very little developed. In females, the ridge had a thinner and more rounded edge.
Often, the length of the beak was only slightly over that of the capillary adornment. The ridge on the head also fulfilled the counterweight function due to the very long, sharp and heavy butt of this species.
The neck was long, flexible, made up of several joints and a series of vertebrae that formed with the axis of the skull an angle that forced the Pteranodon to hold his butt slightly bent down.
The tail of an adult specimen was very short, and the shape of the wings suggests somehow that the flight resembles that of an albatross today.
Like this, the Pteranodon spends a lot of time flying and fishing at sea, strolling impressive distances using the upward currents of the wind to gain the ascent for long periods of time without making too much effort and getting tired very quickly.
The fossils of this remarkable flyer show that he could fly very long distances, sometimes even 160 kilometers, and the speed of the flight was about a wingspan per second, respectively a lift followed by a wings descending.
When lifting their wings, they wore folds to lower the resistance of the air, and as they descended, they removed their legs and wings to get a large surface and squeak easily. Instead of other flying dinosaurs, he had the ability to take off the ground, and when he wanted to have more energy for wing wings, he climbed steep rocks like a real mountaineer, and with the help of his hind legs he took off and started much easier plan.
Reproduction of Pteranodon
During the mating season, the ridge on the head colored had the role of attracting females. They lived in colonies, laying eggs in nests built near the shores, pretty close to one another.
According to the researchers, the number of eggs was very small, and while the eggs were cloaked, females were fed by males that brought them in their beak. After hatching the chickens were fed and protected by both parents, they took the regurgitated food directly from the adult’s mouth.
The adult members of an adult Pteranodon had three fingers provided with sharp claws, and the hind legs had four fingers, also endowed with strong and sharp claws, used both for rock climbing and for supporting body weight.
Dinosaur Pteranodon spends more time in flight, having a good visual acuity immediately notice the desired prey (fish or certain marine reptiles) that swim closer to the surface of the water and by a sudden descent on it she caught her with big and strong beak and a sachet – a leather bag under the lower jaw – just like today’s pelicans do to eat it later.
Populated waterfronts and sea beaches, and its food was made up of fish – the main source of food for flying reptiles and marine reptiles at that time.
