Dull, heavy, sedentary, clumsy … This is how the German scientist Friedrich Theodor Fischer characterized dinosaurs in the 18th century. Since the discovery of their first remains, dinosaurs have enjoyed a very poor reputation: huge creatures weighing about a hundred tons, with a miniature brain, absolutely unable to adapt to climate change, although they have inhabited our planet for one hundred and forty million years. It is not surprising that they were doomed to death in accordance with the laws of natural selection and disappeared without leaving a trace.
Was that how it was? Paleontologists are increasingly pondering this question. For example, the notorious "slowness" of dinosaurs. The English scientist R. Alexander from the University of Leeds, having measured the fossil footprints left by some species of dinosaurs, found that on four legs dinosaurs moved at a speed of four kilometers per hour, and the speed of dinosaurs, moving only on their hind legs, reached thirteen kilometers per hour. And paleontologist Robert Becker of the University of Baltimore believes that the speed of movement of some species of dinosaurs could even reach fifty kilometers per hour.
The dynamism of dinosaurs convinced many paleontologists that these Animals, classified as reptiles for a long time, were … warm-blooded 'They did not feel the need to periodically lie in the sun to maintain the required body temperature.
