Fossils: dinosaurs

Our knowledge about dinosaurs based on fossilized remains found of dinosaurs, which are also called fossils. The first fossils of large teeth were discovered in the twenties of the 19th century. At the time, and adopted the name of the dinosaurs. Subsequently were found not only fossilized teeth and skulls and bones and even large fragments of dinosaur skeletons. Due to the accelerated development of technology and increased construction finds of dinosaurs became more frequent. Basically the remains were found during the underground construction and mines.

After the death of the dinosaur his body fell into the water. Then it was on the bottom and gently sank in the mud. Together with water in the bones fell to the sand and mineral substances. They gradually accumulated in the bones. Over millions of years the mud turned to stone and the bones in a fossil. Then the landscape changed, the sea level fell, the river dried up or changed its course. Gradually the wind and rain I ground off the upper layers of stone, revealing the remains of dinosaurs (fossils), which were discovered by man.

Search for fossils and a reconstruction of the dinosaur

Purposefully, fossils began to look about 150 years ago. At that time, paleontologists had such technologically advanced equipment as it is now, and had no experience of excavation. But even then people tried to recreate the creatures of the mysterious era of the dinosaurs.

In London, in the Park “Cristal palace”has sculptures showing the first attempts of paleontologists to recreate dinosaurs. It iguanadon of sculpture, created in 1843 by Dr. Gideon Mantella, who was the discoverer of iguanadon. Martell assumes that the lizard was similar to a modern serico, magnified many times.

Naturally the resulting iguanadon, had nothing to do with real iguanadons. The fact that paleontologists of the past were just a handful of bones, a handful of teeth and on the basis of this material they tried vossozdat dinosaurs. Of course, there were many errors. Over time there were new bones and even complete skeletons. The accuracy of reconstruction has increased and already in the twenties of the last century, dinosaurs have gained the familiar shape. But the models at that time lacked the realism of movement that modern paleontologists have learned to recreate their accumulated knowledge, experience, and modern equipment and materials.

But camelleri not only dinosaur bones. Scientists find fossilized dinosaur footprints, which can measure not only the structure and size of the paws, but also the way of movement, the width of the steps and speed with which the moving dinosaurs. Currently the search for and excavation of dinosaur fossils is a complex technical process.

Dinosaur fossils are found in rocks formed in the Mesozoic era, i.e. the time in which dinosaurs lived. The fossilized remains of dinosaurs buried in the strata of rocks formed during the Mesozoic. Paleontologists make the search for fossils is not accidental, and conducting preliminary studies to the supposed excavation. Then the teams of specialists to find, if you’re lucky, and remove the bones, teeth, claws. The fossilized remains of dinosaurs with great caution and remove rocks. Later of these bones in the laboratories of the museums collect skeletons. Today in museums already collected a lot of dinosaur skeletons, and modern samples dinosauros become more reliable. Creating realistic models of dinosaurs based on skeletons – the case of sculptors, whose skeletons grow “flesh”.
