Paleontologists from the Institute Paleobiologii YOU find the remains of the flying reptile to 230 million years. Between Ozimek was the largest flying animal of the Triassic period.
While the first large flying animals were ważkami and more than 300 million years ago, had up to 70 cm wingspan, it’s pretty fast, the time of large insects ended. Because 252 million years ago from reptiles first rose, said gliders, and in the sky were only insects about the size, similar to today. these Reptiles had ossification of the skin, resembling elongated ribs which was the side of the blade, for easy glide. Known from the edge of the slate miedzionośnego has about 260 million years Coelurosauravus had 40 cm in length. A little less Kuehneosaurus comes to 215 million years and was 70 cm in length and similar to the wings. And found in Krastova between Ozimek had the membrane of the fly is probably open between the limbs and body.
the First actively flying vertebrates were pterosaurs. The oldest well-preserved their remains date back to 215 million years old from Italy. Maybe they old the same age that between Ozimek. Their wings formed the front legs, which are the same as the bats were flying mucous toe elongated fingers, after the hind limbs. He could, of course, actively fly. Although the largest during the Triassic period was almost a metre wingspan, their bodies were much smaller than ozimka.
as he was between Ozimek?
between Ozimek volans – because it is called the largest flying animal of the Triassic was discovered paleontologów from the Institute Paleobiologii YOU. Numerous skeletons come from the former clay mine in Krastova wheel Ozimka in Silesia, Opole. Was extracted from the rock for 13 years and only now showing the world. Between Ozimek had a very long neck and limb bones, both the front and rear. The membrane itself Russian is not found, as the soft parts are very rarely behave as mineral (though Krasiwo preserved, for example, the gills of molluscs), this kind of frame and hollow bones leaves no illusions that it was an animal flies.
the largest specimens had 90 cm in length, but also material, mineral, dominated by small, separate bones of the limbs up to 10 cm long with a diameter of 3 mm. these Reptiles probably ate insects and small vertebrates. Not been closely linked to pterozaurami that the mucous fly was unbuttoned, mainly on the elongated fingers of the forelimbs. In a period when over Krasiejowem flew ozimki, i.e. approx. 230 million years ago, was just beginning the era of dinosaurs. Comes from a very extensive pradinozaur Silesaurus, and in England, lived there, perhaps, unremarkable ancestor of the large sauropods.
the world looked Like ozimka?
In the era of the late Triassic, the Earth looked completely different than now. The continents were one supercontinent Pangeę, which on all sides was surrounded by the ocean Panthalassą. The climate was dry and warm. The poles were free of ice caps, a large part of the area probably occupied the desert. The area is very extensive today, was then in the area of climate podzwrotnikowego. The climate of this proposal is obvious sezonowością. Played for two seasons, dry and rainy. In a landscape dominated by coniferous forests. Perhaps they were habitat ozimka. Soar from tree to tree, he could get away from nadrzewnymi predators and may be hunted. The largest land predator was then a very extensive reptile Polonosuchus silesiacus. He had more than 3 m in length and ab out 70 cm in height.
Looks a bit like today’s crocodiles, however, remotely related to it. His massive skull, equipped in a number of large sharp teeth. Between Ozimek however, was not an attractive prey, I think that he fell to the ground. Polonozuch probably hunted mostly on usual then arising in Krastova aetozaury genre of Stagonolepis olenkae. These omnivorous animals by becoming the prey size polonozuchom. Their body is covered with armor joint, as in modern us battleships or łuskowców. Their triangular skull was topped with ryjkiem, which probably served to cover our wykopywania food from the earth.
Presumably, were a way of life similar to the present wild boar, but ryjka also shows the presence of a powerful olfactory channels in the skull. Other terrestrial animals is very extensive, has already been mentioned, reaching 1 m in body length, herbivores silezaury, probably related to the later dinosaur ptasiomiednicznym. To find them nearly full of the remains in Krastova allowed to identify the bones similar to animals found in the different guiding Triassic fossils from around the world.
Krasiejowskie Triassic forests crossed by numerous slow-flowing river. Their system was very dynamic and varies over time. Sometimes there is a local lake. It is due to the presence of these watercourses and water bodies, as well as the specific characteristics of the chemical flowing into them of the waters of the bones of animals buried in their depths, not decomposed, but was skamienieniu and after 230 million years could be extracted and studied paleontologów. Reservoirs were the preserve of large fish-eating amphibians, the temnospondyli of the genus Metoposaurus (up to 2 m in length), and their edge – of-prey Cyclotosaurus (up to 3.5 m in length). General habitus of the body of these animals was like a little living today, salamanders or newts (although they are closely related).
Typical is the structure of their skulls that they’re flat and wide. Other large aquatic predator is very vast was fitozaur reptile of the genus Paleorhinus, which appearance similar to today’s crocodiles gawiale, residents of the river Ganges. Fitozaury as gawiale, had a long, narrow mouth is armed with small teeth piłkowanymi. Narrow jaw put a small resistance in the water, allowing you to quickly capture fish.
Currently Krasiwo works great jurapark family Association “Delta”, and the Baltic States and Solec Kujawskim. Located within the public Museum you can observe the largest concentration of original skulls and other fossils from very extensive, and its surrounding models of dinosaurs from around the world in full size. Also paleoakwarium, in which “swim” sea monsters a millions of years ago. Currently, excavations in the former wyrobisku the mine are conducted on a small scale the University of Opole.
