According to Newsweek, the snake fossil and the bug remains found alongside it were extensively studied through multiple analysis methods, including CT scans, X-rays, microscopes and even particle accelerator technology.
It turns out that ancient snakes formed much the same way modern ones do.
It's the first example of a dinosaur-age snake that clearly lived on the forest floor and that's significant for a number of reasons.
The new fossil shows us that by around 99 million years ago, snakes had found their way from swamps or sea shores to become fully-terrestrial in forested environments.
A second specimen found in Myanmar by the same team includes a preserved fragment of shed skin.
The authors named the new species of snake Xiaophis myanmarensis.

"Amber collects everything it touches - kind of like super glue - and then holds onto it for a hundred million years", he said.
"Whether or not these early snakes were giving live birth, which is common in modern snakes, or whether they were hatching from eggs, is unclear".
"No one has ever seen a fossilized baby snake of any kind whatsoever".
"We need to learn that snakes that were so abundant in the southern hemisphere reached up to the northern hemisphere and this specimen helped us to answer part of that question", Simones said.
The creature has been frozen in time for 99 million years.
Both are extremely similar to snake species living today, a testament to how well-adapted little these little, slithering predators are to their ecological niche. National Geographic placed the snake as possibly related to a group of modern snakes found in Southeast Asia.
According to the research team that made the discovery, the baby snake fossil found at Myanmar is the oldest one ever unearthed from a prehistoric site.
The two pieces of amber also contained insects, remains of plants and invertebrates, indicating the snakes were living in a humid and warm tropical rain forest with a freshwater habitat.
Previously, scientists reported that the first snakes have appeared on the land 128 million years ago.
