Some species of old crocodiles strolled on their 2 hind legs such as dinosaurs, record scientists.
They measured over 3 meters (9.8 feet) in size, the searchings for indicate.
The scientists first thought the similar-shaped fossilized impacts were from another old pet known as the pterosaurs, says Anthony Romilio, a paleontologist at the College of Queensland.
"THE FOOTPRINTS MEASURE AROUND 24 CENTIMETERS [9.4 INCHES], SUGGESTING THE TRACK-MAKERS HAD LEGS ABOUT THE SAME HEIGHT AS HUMAN ADULT LEGS."
"At one website, the impacts were at first believed to be made by a huge bipedal pterosaur strolling on the mudflat, we currently understand that these were bipedal crocodile prints," Romilio says.
"The impacts measure about 24 centimeters [9.4 inches], recommending the track-makers had legs about the same elevation as human adult legs. These were lengthy pets that we estimate mored than 3 meters in size. And while impacts were everywhere on the website, there were no handprints."
Quickly, however, they quickly found hints as to why there were no handprints."Typical crocodiles stroll in a squat position and produce trackways that are wide," says Kyung Soo Kim, a teacher from Chinju Nationwide College of Education and learning.
"Strangely, our trackways are very narrow looking—more such as a crocodile harmonizing on a tight-rope. When combined with the lack of any tail-drag notes, it became clear that these animals were moving bipedally. They were moving similarly as many dinosaurs, but the impacts weren't made by dinosaurs," Kim says."Dinosaurs and their bird descendants stroll on their toes. Crocodiles stroll on the level of their feet leaving clear heel perceptions, such as people do."
The scientists found the impacts, outdated in between 110-120 million years back, after evaluating pet track websites in what is currently known as Southern Korea.
They at first questioned the lack of hand perceptions from the trackways, considered that today's typical crocodiles are "four-legged" or quadrupedal.
"Fossil crocodile tracks are quite unusual in Australia or europe, so finding a wealth of nearly one hundred impacts was remarkable," Romilio says.
