Traces of a large pterosaur in Korea attributed to terrestrial biped crocodylomorpha

The traces of extinct animal near the city of Gyeongju in South Korea that were initially attributed to large pterosaur, was a bipedal footprints crocodylomorpha, reported in Scientific Reports. It is likely that other similar traces do not belong to large pterosaurs, and some other reptiles, and the pterosaurs did not walk the earth on two legs.

In the superorder crocodylomorpha devoured (Crocodylomorpha) includes all modern crocodiles and many extinct forms of living around the world. However, in Asia, which is now inhabited by many species of true crocodiles, Gharial and alligators, almost can not find traces of extinct Mesozoic crocodylomorphs. This is attributed to the fact that there was no favorable conditions for their preservation: most of crocodylomorphs had spent more time on land, to leave the prints of their paws.

However, on the territory of modern Europe, North America and Africa show signs of lower Jurassic representatives of the genera Batrachopus and Crocodylopodus. These animals, apparently, was the ground. Recently, the paw prints Crocodylopodus found in South Korea, in the sediment layer Aptian (125-112 million years old, lower Cretaceous) of the Jinju formation near the town of Sacheon.

Now Australian, American and Korean paleontologists led by Martin Lockley (Martin G. Lockley) from the University of Colorado in Denver described several new series of footprints which they found in the Jinju formation. Judging by the shape, the prints belonged to the clutches of crocodylomorpha from the genus Batrachopus previously unknown species. Animal called Batrachopus grandis, as his legs were at least twice larger than that of other batrachus. The length of the traces of B. grandis reached 24 inches, and closely related species should not exceed 8 inches. Judging from these values, the length of the body Batrachopus grandis was about 3 meters.
