Assassin Flies Found in Burmese Amber. Paleontologists have described a new species of assassin fly found preserved in two pieces of Burmese amber. For more than 100 million years, these creatures have ruled the world of insects as a top predator.
It takes thousands, if not millions, of years for resin to become amber. The latest amber-trapped bugs were dated at 230 million years old. Amber also acts as a preservative, enabling scientists to microscopically identify whatever bug is trapped inside.
