Four-legged dinosaurs could walk on two legs, but only in certain conditions

the Large size of sauropods is perfectly protected them from predators
More recently, paleontologists found that the most dangerous dinosaurs in the story were not tyrannosaurs Rex, and . However, the fact that the record for the weight and size of the ancient creatures were , which included Diplodocus and Brontosaurus, no doubt. Millions of years ago they lived on all the continents and unlike other dinosaurs were like birds and huge elephants. They moved their heavy bodies with four thick limbs, but a recent discovery scientists have uncovered a very surprising feature of their gait. It turned out that in some cases a huge sauropods could walk on two front legs, raising back up. But how is this possible?
The Results of this study were published in a scientific journal . The theory that a huge dinosaur could walk on two front legs, was made by scientists more than a decade ago. The fact that it was then in the American state Texas was found by the footprints of sauropods, and only the front — rear them as if they never happened. Then the researchers assumed that the huge dinosaurs used the forelegs as a support when crossing deep rivers. However, this hypothesis was quickly rejected because the sauropods are considered to be terrestrial dinosaurs, not amphibians.
So, according to scientists, swimming sauropods
How were dinosaurs swimming above us?
However, in 2007 scientists once again had to recall a previously rejected theory. Then, in the limestone quarry Texas town of Glen rose was found dozens of new dinosaur footprints, which lived approximately 110 million years ago. Like last time, on the surface nothing was visible but the outlines of the forelimbs and the hind legs were not touching the ground, or rendered her a very small pressure. Scientists believe that the footprints were left by sauropods that is because the width of the prints up to 70 inches.
Footprints sauropod, found in Texas
As a scientist it is difficult to imagine how the huge dinosaurs could walk on two front legs on the ground, they again suggested that they thus sailed. It may be that crossing the rivers and lakes, the sauropods rested on thick legs on the bottom and started, gradually picking up speed? The fact that these dinosaurs were not amphibians-creatures that actually does not prevent the existence of such assumptions. After all, are also considered terrestrial creatures, but this does not prevent them to cross the shallow water.
Generally, the sauropods are among the most interesting to study dinosaurs. Paleontologists believe that the large size of their bodies good , because to hurt such a huge establishment was extremely problematic. But its large size the sauropods also harm the planet because it consumes a lot of vegetation. Just imagine that in the nearby woods there are animals and started eating the trees — a few weeks later the trees probably would only have guns.
