Scientists have discovered well preserved insects dating back over 230 million years to the Triassic era.
The preservation process occurs when the insect becomes trapped in tree resin which then hardens and eventually fossilizes, resulting in a specimen that can survive for hundreds of millions of years.
The hunt in this case was particularly painstaking because the insects are too small to see with the naked eye. Researchers had to carefully examine over 70,000 droplets of amber in order to find what they were looking for.
"They are about 230 million years old, which puts them in the Triassic time period, and about 100 million years older than what had been the previously known oldest critters trapped in fossilized tree resin, or amber."
