Rhamphorhynchus was a Long-tailed flying dinosaur who lived in the Mesozoic era, during the Upper Jurassic period. The fossil remains of this prehistoric animal were discovered in Germany at the beginning of the 19th century. 19th century, and for the first time was described by paleontologist C. Ernest Hermann von Meyer in 1847 and was named Rhamphorhynchus muensteri.
Since several skeletons were found in both Germany and England, and in Tanzania, which were of different dimensions, they concluded that they were of different age, from little ones to adults, and on the other hand the hypothesis that there were several species of Rhamphorhynchus, namely a number of 21 species of this genus.
Based on the analysis of the largest skeleton of Rhamphorhynchus found to date, the length of this dinosaur was estimated to be 1.26 m, weight 2 kg, and the wings open 0.5-1.8 m.
The Rhamphorhynchus dinosaur had a long tail that was three times larger than the trunk and was finally provided with a terminal oval shape in the younger and triangular form of the adult specimens. The body was covered with thick, furry hair that was designed to protect it from cold and to provide a good camouflage.
The body was also heated by the warmth of the sun while the dinosaur held its open wings. The skin was crossed by blood vessels, muscle tissues that had a role in regulating body temperature. It seems that the wings have developed from the forelegs (as the researchers think), the patch extended through the fourth long toe and reached the hind limbs, leaving only their paws free, with sharp claws.
The skull was thin and long, with the jaws arched upwards, with very sharp teeth, so ordered that they were passing by others, and by closing their mouths they were able to crush the fish or insects they were feeding.
The weight of the body was greatly reduced due to the fact that the bones were empty and had small holes connected to the air bags of the lungs. This ensures the constant flow of oxygen, as well as the regulation of the temperature, the cooling of the body during the flight.
Due to the large wings, this dinosaur was able to fly very easily in flight, and on the ground to adopt both biped and quadruped. Perhaps this dinosaur had a previously developed brain lobe that helps him coordinate his movements in flight. On the ground, it is moving heavier, its limbs being quite weak, but in flight it has the ability to reach a high speed and then to let itself be carried by the wind.
Rhamphorhynchus fed mainly with fish.
