During the Cretaceous period grazed beagle animals of small size, giant predators that moved on two legs and a great variety of flying reptiles. According to the researchers, the birds developed from dinosaurs belonging to the group of theropods.
In other words, the Cretaceous was especially a period of predators. Dsungaripterus was a species that lived in the early Cretaceous period about 120 million years ago.
Its fossil remains were discovered in China and Tanzania and described by the paleontologist Chung Chien Yaung in 1964. Based on their analysis, it was concluded that there were two species: Dsungaripterus well (from China) and Dsungaripterus brancai (from Tanzania ).
Dsungaripterus belongs to short-range flying dinosaurs called Pterozaurians. From this group the gigantic proportions were the Pteronodon (with a wingspan of 7-8 m), and the one who had an active active flight was the Dsungaripterus.
Its wings were 3 m wide and were made up of a thin but durable membrane. This membrane stretched from the front limbs to the hind legs, leaving the free back paws.
The peculiarity of this species was due to the long ridge on the head, which covered the area between the tip of the nose and the forehead. Its role was to recognize the species, improve flight quality and signaling. The specimens of this species were different from each other by the appearance of this adornment on the median line of the muzzle.
In males the size of this increase was probably higher than in females. Some researchers have hypothesized that this ridge could act as a helmet during the flight, others thought it would be just an element of gender differentiation, or of attracting females by males during mating.
Dsungaripterus also impresses with the short crest placed in the back of the head.
These prehistoric reptiles adopted two forms of flight – one active (made with well-developed flight muscles) and one planed (made up and down, holding wide open wings and legs when they descended and snuggled them a while).
On the ground, the Dsungaripterus moved heavily on the paws of the four thin limbs, always having the wings tight. The weight of an adult Dsungaripterus was estimated by experts at 7 kg. It seems that such a specimen had an easy body, and that’s because most of the bones were empty inside.
During the mating season the males competed with each other in the capillary ornament look to impress the females. Each of them chose their partner, coming to him with his head slightly gone as a sign of obedience. As in any confrontation, there is a winner and a winner. The male losing to the rival was separate and, with his loneliness, his chances to catch the attention of a female were small.
Dsungaripterus lived in the shores of the waters and fed with fish, crabs, molluscs, plankton, already dead animals and insects. His skull was 50 cm long, the front of the toe was teeth-free, only the jaws of the jaws were small teeth, sharp, sharp, slightly bent upward.
These were tools to break and tear hard shells or crabs.
