A new study has revealed that about 142 million years ago, two predatory dinosaurs strolled along a beach and left their large footprints behind in the sand.
These footprints, that have now become fossils, are aiding researchers to understand what kind of dinosaurs lived in regions, that is now modern-day northern Germany. The foot trails show that one dinosaur was large, and the other was small. Their fossil copies suggest they walked at a brisk but strolling pace, about 3.9 mph (6.3 km/hour) for the large one and about 6 mph (9.7 km/h) for the little one.
At some points, the small dinosaur began racing, possibly to keep up with the speed of the large one. The footprints also suggested that the dinosaurs slid at few places of wet sand, as said by study researcher Pernille Troelsen. She earned her master’s degree in biology from the University of Southern Denmark in June.
The dinosaurs’ relaxed paces are slow, as against scientists who estimated carnivorous dinosaurs to run faster than about 25 mph (40 km/h), Troelsen said.
