Based on fossil data and assumptions scientists, paleontologists were drawn, so-called sketch on the dinosaur. They built up the muscles on the skeleton - it was not difficult, because the bones are traces in the form of slots in the place of attachment of muscles, put them into the skin, they gave their eyes, even created fashion and you a virtual models, run, twisting their heads and waving tails. But, despite fashion and you all efforts, remains unclear and what color they were, that they had a leather? These issues remain relevant today.
Scientists know a lot about dinosaurs: they distinguish various types, know the structure of the skeleton of what they ate and even something about the behavior, but the question is - how did the dinosaurs looked outside? Based on fossil data and assumptions scientists, paleontologists were drawn, so-called sketch on the dinosaur. They built up the muscles on the skeleton - it was not difficult, because the bones are traces in the form of slots in the place of attachment of muscles, put them into the skin, they gave their eyes, even created a virtual models, run, twisting their heads and waving tails. But, despite all efforts, remains unclear and what color they were, that they had a leather? fashion and you These issues remain relevant today. Let us consider first things first. Leather related to those body parts that do not turn into fossils and not stored for centuries. But paleontologists - people patient and skurpuloznym, still lucky to find some of her prints. For example, it was found omatozavra (platypus dinosaurs), caught in a sandstorm and was buried alive during dry sand. In such circumstances, his body turned into a mummy, and then fossilized and compressed into sand preserved vdbytky skin. Omatozavra skin was smooth, dry and supple, between her soft parts housed small convex fashion and you particles thicker horny skin. Under these bulges located bony plates. Similar plates were also the ancestors of dinosaurs (Thecodontia) and their relatives - Crocodylomorpha lizards, from which emerged the modern crocodiles (Crcodilia). We can assume that this is the type of skin was widespread in dinosaurs. In pantsernyh lizards bony plates developed best - their thickness reaches 5 cm, they adhere to one another. Top and side of the body, they formed a strong yet flexible shell. It covers the horny layer of the skin, creating picture, like a mosaic. In the sharp-pointed or curved bony plates fashion and you horn leather reinforced these forms, creating a thick-tipped horns or tubercles. Most likely, the skin resembled in structure the skin of three groups fashion and you of modern reptiles - turtles: (Chelonia), crocodiles fashion and you (Crocodilia), and dzoboholovyh (Rhyhciophalia), but fairly unknown whether they had scaly covering like lizards and snakes. In terms of anatomy in modern reptiles, skin represented by two layers: the upper layer of the epidermis and continuously rohoviye zluschuyetsya its underlying fashion and you bottom - regenerative, living layer and is located in the heart of kutys - own skin. Outside the body covered with horny scales like zduvalosya above. Keratinization of the epidermis and the formation of flakes or platelets counts, because protecting animals from dehydration. In some species by horny scales are bony plaques that develop as ossification kutysu. Skin tight to the body. Skin glands in reptiles there. Remains unclear greetings of color and its pattern. All color images fashion and you - this is only an assumption imagination of researchers and artists. It should be emphasized that the nature of the body color is adaptive in nature, or to camouflage or protection from solar radiation. For example, zebras and gazelles in the African savannah with striped and spotted coloration that camouflages them in the environment. Takezh camouflage color and with lions and cheetahs, and leopards, which helps them hunt upishno ambush. Great as mammals such as elephants, hippos and rhinos do not require masking as protect them from predators large size, and the horns, tusks and fangs, and the color of their skin oberhaye them from burning high levels of solar radiation. It is logical to assume that dinosaurs were the same devices and pattern on the skin of small herbivores consisting of spots and stripes in small carnivores and should be band, while the large color was obviously brown or dark and monotonous. The most interesting variety of dinosaurs fashion and you gained from a number of Ornithischia (ornitomiyi) weighing compelled to move on four legs, they were armed with a wide variety of spikes, horns, fashion and you plates and covered with armor. These included such dinosaurs like Stegosaurus. Unlike the dinosaurs, ornitomiyiv, dinosaurs, zaurimiyi had skin that was anatomically the disposal facility
