An international team of paleontologists discovered Footprints left by a dinosaur in China The size of the cat is approximately 100 million years.
Anthony Romilio, a researcher at the University of Queensland, was part of the team that studied the clue that was originally created by la profesora asociada Lida Xing From China University of Geosciences.
“This footprint was made by the well-known herbivorous armored dinosaur Like stegosaurus, Including the famous Stegosaurus dinosaur family. He said in a statement that, like stegosaurus, this little dinosaur may have spines on its tail and bone plates as adults.
“It covers an area of less than six centimeters, This is the smallest stegosaurus footprint known in the world. This is in stark contrast to other Stegosaurus tracks 30 cm long found in Chinese stadiums and 80 cm long tracks found in Broome, Western Australia and other places,” he added.
The small footprints described in Palaios magazine have similar characteristics to other footprints Stegosaurus There are three short, wide and round finger markers.
However, the researchers found that the imprint was not as elongated as the larger corresponding footprint found on the tracking site, indicating that the young stegosaurus He has different behaviors.
“Stegosaurus usually They walked on the ground with their heels, Romilio said: “Like humans, but the limbs are a long way. This way is long.” This little clue suggests that the heel of this dinosaur lifted the ground, just like a bird or a cat today. . In the past, when dinosaurs walked on two legs, we would only see such shortened trajectories. “
Xing said that the young stegosaurus is reasonable With walkers toe. He said: “This is possible because this is the ancestral state and posture of most dinosaurs, but stegosaurus may also turn to walk with age.”
“The full set of clues provided by these small footprints will provide us with the answer to this question, but unfortunately, We only have one footprint”Add to.
Find out Path It will be a challenge for investigators in a crowded track scene. Xing said: “The footprints made by small armored dinosaurs are much less than those made by other types of dinosaurs.”
“Now that our research has identified nine different dinosaur footprint points in the area, we will observe more closely whether we can find more of these small footprints.”
