Scientists have found an evidence of pollination trapped in an ancient piece of amber, which is found to be the oldest evidence of pollination.
This research has been published online in the Proceedings of the National Academy of Sciences.
Scientists have found that the pollen grains are attached to the insects about 105 to 110 million years ago. The pollen grains are thought to be from a ginkgo tree. The insects are found to belong to the new genus of thrips that is still present today. The insects are thought to be moving from plant to plant in search of food and gathered pollen in the way.

There they generate a detailed 3D image of the insects with the help of synchrotron X-ray tomography and found specialized hairs on the body of the insects, which enabled the pollen grains to get trapped.
“This is the oldest direct evidence for pollination, and the only one from the age of the dinosaurs,” study researcher Carmen Soriano said in a statement. “The co-evolution of flowering plants and insects, thanks to pollination, is a great evolutionary success story.”
It is estimated that the flowering plants were first evolved around 130 million years ago.
