The earliest fossils of snakes are found in pumpkins and collection subjects.
"Science," "The New York Times" Scientists have discovered the remains of a small snake that lived 100 million years ago in a small pumpkin found in Myanmar. "CBS". According to mainstream media such as the BBC, the snake was two small reptiles that lived in the middle of the Cretaceous (about 135 million to 65 million years ago) before the birth of the Tyrannosaurus. Scientists who discovered fossils named this reptile "Xiaophis myanmar ensis".
This fossil is the oldest fossil snake ever discovered. In addition, it is expected that the snake fossil, which lived in the forest environment, be preserved as is, and it is expected that it greatly helps to study not only the snake but also the natural environment of the Cretaceous.

Moving to the vertebral and thriving bones in the forest
The newly discovered snake fossil is about 5cm in length and about the size of the body. a golf ball. Scientists have scanned the inside of the snake using x-rays to find the skull of the snake.
As a result, scientists came to the conclusion that snakes that had lived in the water in the first coastal areas gradually moved towards the forests. Over the course of hundreds of years, he discovered that snakes turned their vertebrae into the same structure as now.
A related article appeared in Science Advance on the 19th. The title of the article is "An embryonic-neonatal mid-Cretaceous serpent in Myanmar amber", which indicates that a fossil snake baby who lived in the Cretaceous was found inside the pumpkin.
According to the New York Times, Professor Lida Xing, paleontologist at the Geological University of China, discovered the pumpkin in 2016.
Singh found a baby bird, a dinosaur feather in an amber sold in a market of antiques.
Singh, who bought a pumpkin, went to Canada and went to the Snake of the University of Alberta, where he was a member of the University of Hawaii. 39; Alberta. I met a professional paleontologist, Michael Caldwell. Professor Caldwell showed Prof. Singh the amazing snake fossils recently discovered on pumpkins.
The two men are the earliest fossilized fossil fossils discovered by Singh and were discovered by Singh as the first fossil fossils of snakes. I could confirm.
Living on the shore and migrating to the forests of Myanmar
The snake found in the pumpkin is a millipede, or a snake I was in shape. But in reality, he was trapped in a pumpkin that came out of the tree like a snake. Professor Singh and Professor Caldwell attempted to badyze these serpent snakes by comparing them to existing snake fossils.
The study was focused on anatomical badysis. A specially designed micro CT (computerized tomography) scanner and a particle accelerator synchrotron have been introduced.
Both researchers accurately badyzed the fossils and discovered that puppies were the ancestors of snakes, and that they were the ancestors of snakes. Pipe pipe snake lives in the Southeast Asian Malay Islands with grbad snakes, a poisonous snake
These fossil snake fossils have very small vertebral bones like the present snake. However, he had a spinal cord tube that was much smaller than the current snake. Professor Caldwell explained, "These vertebrae tell me exactly 99 million years ago that cubs have evolved."
Professor Caldwell said, "As the environment was changing, the spine of the snake was changing, This change in body structure has continued until now, and we have now been able to move in a gyratory and powerful way. "
Ryan McKellar, paleontologist at the Royal Saskatchewan Museum, Royal Canadian Museum, London, author of the paper,
At that time, Dr. McKellar was promoting a forest environment where snakes could enter and exit without much power. I see.
Dr. McKellar said, "Through the history of snakes, we can see that the snake was inhabited in the early Paleozoic forests, there are 225 million to 65 million years (including Cretaceous) We can estimate the history of ancient biological evolution, including the Mesozoic era. "
While a flourishing snake in the emigre coastal region From the trees migrating to the dump, the snake fossils were found in Myanmar because geographically, it was an island region connecting Asia and Australia. It is estimated that he left traces of snakes entering the pumpkin.
Dr. McKellar argued that "it is very likely that snakes in amber were moving home."
