Giant bones, sometimes found in the ground, in antiquity were considered the remains of heroes of the era of the Trojan War, in the Middle Ages and up to the XIX century. – The remains of giants, which are mentioned in the Bible and who died during the Flood; in the Far East, they were considered dragon bones and attributed healing properties to them.
In 1824, the President of the Royal Geological Society, William Buckland, gave a report on a find made in 1815 in the Jurassic shales of Stounsfield (Oxfordshire) and consisting of several bones and a fragment of the “antediluvian” animal. Having resorted to the help of a prominent specialist in comparative anatomy Georges Cuvier, Buckland classified the find as the remains of a giant predatory lizard (Latin sauria) and, accordingly, called it a megalosaur – “a huge lizard”.
In 1826, Gideon Mantell, a surgeon from Lewis (Sussex county), a full member of the Linnaean Society, likewise presented in the Geological Society his found teeth of a previously unknown species, to which he gave the name iguanodon (lit. iguanas In 1833, he described Gileozavr, a representative of the armored lizards of the Ankylosaurs.
In 1842, English biologist Richard Owen, stating the undoubted similarity between these three species and their difference from modern reptiles, singled them out into a special suborder, calling it Dinosauria (“terrible lizards”).
The discovery in 1858 in the United States of a well-preserved skeleton of the hadrosaur overturned the idea of dinosaurs as four-legged animals, showing that dinosaurs could walk on two legs. In the next few decades, representatives of most of the major groups were discovered; An important merit in this belongs to the American palaeontologists Othniel Marsh and Edward Kop, who discovered and described a total of 142 new species, including apatosaurus and brontosaurus (later they were attributed to the same genus), diplodoc and stegosaurus, monoclone, triceratops, etc. The accumulation of material led to the division of dinosaurs into families of birds and lizards (1887).
In the first half of the twentieth century, most of the scientific community mistakenly believed that dinosaurs were bulky, lethargic animals. Most studies conducted since 1970, however, indicated that dinosaurs were active animals with increased metabolism and numerous features for social interaction.
In 1964, the find of Deinonich produced a new scientific revolution, since it was clear from the structure of the dinosaur that it moved relatively quickly, which led to the conclusion that it was warm-blooded. The idea of warm-bloodedness made it necessary to revise old ideas not only about physiology, but also about their behavior, which was confirmed in 1979, when evidence of parental instinct and social behavior of lizards (incubation, protection and feeding of cubs) were obtained. Finally, a comparison of Deinonich’s upper limbs with a bird’s wing made it necessary to assume their proximity and the origin of birds from them (or even their belonging to this super-detachment), which later became evidence of the discovery of plumage of a number of dinosaurs. In 2005, scientists managed to isolate collagen from the remaining soft tissues of a Tyrannosaurus and use its chemical composition as further evidence of dinosaur affinity with modern birds.
