A paleobiologist was looking for signs of small mammal bones on Seymour Island when he came across a fossilized cocoon that contained the ancient seed.

Upon further examination it was determined that the cocoon and its contents were at least 50-million-years-old, making it the oldest animal sperm ever identified.

They determined it belonged to a crawfish worm — also known as a yabbie parasite, which creates a cocoon that protects an egg and sperm during reproduction.
