2020 National Geographic Partners, LLC. A great many of the fossils of crocodiles are virtually identical to the crocodiles we see today. And there were no tail-drag marks that you find with modern crocodiles.However, in a prepared statement, Professor Kyung Soo Kim from Chinju National University of Education, who led the research, said the team soon found clues as to why there were no hand prints.“Typical crocodiles walk in a squat stance and create track-ways that are wide,” Professor Kim said.“Oddly, our trackways are very narrow looking – more like a crocodile balancing on a tight-rope.
Unfortunately, while it has the more impressive name, Terrestrisuchus may wind up being assigned as a juvenile of another genus of Triassic crocodile, Saltoposuchus, which attained … It's difficult to say how these prints were preserved, but perhaps the creature left the prints in wet mud just before the lake retreated, allowing the prints to dry and harden. Trackways at the Sacheon Jahye-ri site in South Korea appear to have been made by a large crocodile relative that walked on two legs. During the lower Cretaceous, the track site was a lake surrounded by muddy ground, "which made for making good tracks," Lockley told Live Science. âThat may be why today you donât see crocodiles running after antelopes on the savanna,â Lockley says. However, instead of being made by quadrupedal, cat-sized crocodiles, the Sacheon fossil tracks are large. All rights reserved

For example, pterosaurs likely used their wings while walking, meaning they walked on all fours. “And while footprints were everywhere on the site, there were no hand prints.”Dr Romilio said that, with fossils of creatures who got about on all fours, there is the potential for the hind feet to have stepped into the impression made by the hand and ‘over-printing’ it. It had somewhat telescoped eyes and a long snout comprising 75% of the length of the skull. Over 110 million years ago, during the Cretaceous period, the southern coastal area of South Korea, near the city Jinju, was covered by extensive lakes.
