A study carried out by scientists at the University of Alberta (USA) and published in the Chinese Science Bulletin magazine has revealed that dinosaurs were capable of swimming paths . They have reached this conclusion after finding, in lands that coincide with the bottom of a prehistoric river located in present-day China , marks on the tips of the fingers and the nails of the hind legs that could only have been created by these giant reptiles while they swam in its waters. The claw tracks identified in the study cover a distance of 15 meters, indicating that the dinosaurs were capable of swimming long distances with coordinated limb movements .
The footprints could have been the work of a theropod carnivorous dinosaur, probably a tyrannosaurus or a Sinocalliopteryx , which would be about a meter in height, the researchers speculate.
