The fossil of a baby snake was found buried in amber.
The creature has been frozen for 99 million years
The snake lived in present-day Myanmar, in the age of dinosaurs.
Scientists say the snake fossil is "incredibly rare."
"This is the very first baby snake fossil we've ever found," said Prof. Michael Caldwell from the University of Alberta in Canada BBC News.
The baby snake lived in the forests of Myanmar during the Cretaceous. It was given the name Xiaophis Myanmarensis or the morning snake Myanmar
. A second amber fossil was discovered, which seems to contain some of the shed skin of a much larger snake. It is unclear whether this is an animal of the same species.
How is the snake frozen in time?
The animal got stuck in tree sap, a sticky substance that can preserve skin, scales, fur, feathers or even whole creatures.
"It's the super glue of the fossil record," said Prof. Caldwell.
"Amber is absolutely unique ̵
What does the new discovery say about these iconic creatures?
The body of the serpent is seen inside the piece of amber, consisting of 97 vertebrae and attached ribs. Interestingly, the snake's head is missing.
The bones of the creature were analyzed in a synchrotron, an extremely powerful source of X-rays, and compared to those of living snakes.
Anatomical features indicate that the snake's spine appears
Scientists say that the snake may have survived tens of thousands of years in a primitive state before becoming extinct.
What do we know about where it lived?
Fragments of plants and insects found inside the amber confirm that the snake lived in forests.
This has not been shown for this time, as the few others found The fossil snakes found are from rocks that are connected to rivers or the sea.
Dr. Ricardo Pérez-de la Fuente from the Natural History Museum of Oxford University, who is not affiliated with the research team, said that the find is "invaluable evolutionary and evolutionary data on ancient serpents".
What is special about amber fossils?
Myanmar is considered a treasure trove of exciting fossil finds from the Cretaceous period 145 to 66 million years ago.
Recent finds include the tail of a feathered dinosaur, an ancient arachnid and a cargo of prehistoric frogs.
The new discovery is reported in the journal Science Advances.
