In the Spanish province of La Rioja, archaeologists have found dinosaur prints about 120 million years old. With their help, they calculated that prehistoric reptiles could move at a speed of about 50 km/h. Details were published in Scientific Reports.

To calculate the speed of the dinosaurs, scientists measured the length of the prints and matched it to the height of the hip. In doing so, they also took into account the stride length – the distance between two prints of one limb.

As the study showed, the tracks belonged to bipedal carnivorous dinosaurs – theropods. According to archaeologists, they reached two meters in height and up to five meters in length. According to calculations, they could accelerate to 45-50 km / h.

According to scientists, this find proved that not all two-legged reptiles were as slow as tyrannosaurs. According to numerous reports, their average speed was 25-40 km / h. They could not run faster: their bones could not withstand such a load.

In 1938, the tracks of ornithopods, herbivorous dinosaurs, were found in Texas. Scientists also measured their speed, but it turned out to be less than that of theropods living in Spain – about 27 km / h.
