St Petersburg University scientists found an ant of the genus Manica in a piece of amber in collection of the Kaliningrad Amber Museum. Such ants had previously been found only in the mountains of Europe, the Caucasus, North America, and Japan. The scientists report that the age of the finding is about 33.9–37.8 million years. This is the most ancient and first known fossil species of this genus.
