New Delhi: An international team of scientists discovered the world’s oldest sperm inside a resistant animal trapped in the resin of a tree in Myanmar around 100 million years ago. The researchers, led by the Chinese Academy of Sciences, found sperm in a new species of resistant small animal, which they named “Myanmarcypris Hui”.
They estimated that this animal must have coexisted just before entering the resin of the tree about 100 million years ago.
Researchers said fossil sperm were exceptionally rare, before the discovery of 17 million year old sperm.
