One-legged dinosaur, a small carnivorous dinosaur in Asia, found only a bird-like sole bone.

One-legged dinosaur is a carnivorous dinosaur of theropod. It was born at the end of Cretaceous 80 million years ago. The first fossils were found in Mongolia, Asia. It is said that its body length can reach 2 meters. Only one claw fossil was found in the fossil, so some people speculated that it might be a dinosaur used to standing on one foot, and then gave it a Mongolian name? One foot? .

Appearance characteristics of one-legged dragon One-legged dragon belongs to a small carnivorous dinosaur. Its body length is only 2 meters, ranking only 525th among more than 700 known dinosaurs, and its body shape is similar to that of Pink Dragon, Asian Dragon and Abalone Spinosaur. Since the Monopod belongs to Nautilus, it is speculated that it may also have a beak like a modern parrot, and it also has a bony crown on its head. When standing, one foot is put away and slightly attached to the other foot. The tail tip is similar to a red dragon, with a small amount of feathers, and looks like an ostrich.

At present, only the sole and palm fossils have been unearthed. The first batch of fossils were unearthed in 1970, and were excavated by a joint Polish and Mongolian archaeological team. Finally, a very small theropod dinosaur fossil fragment was found in South Gobi Province of Mongolia, but it was found in 10+after a study of10 years. One-legged dragon Because only one fossil sole was found at that time.

The normal one-legged dinosaur fossil contains the extension bone and tarsal bone of the left foot, while the accessory specimen contains a metacarpal bone, a sole bone and a large extension bone. So now, because the fossil is incomplete, we don't know whether the one-legged dragon really stood on one foot, but only one foot bone was found in the fossil belonging to it, so this may also prove this unique one-legged feature.

For example, in the docile one-legged dragon fossil found in North America, it is only a sole bone, although it was discovered by William in 1933. Parks was classified as a bird-like dragon, but in 1989, it was corrected back to Diptera. However, the docile one-legged dragon is also controversial, because its fossil excavation site is actually far from the one-legged dragon fossils of the same genus, so some people object to this classification.
