Scientists have discovered the oldest sperm in the fossil record, which dates back nearly 100 million years, inside a crustacean that was preserved in amber from Myanmar.
The Cretaceous sperm cells “double the age of the oldest unequivocal fossil animal sperm” making them “by far the oldest sperm of any kind yet identified,” according to a study published on Wednesday in Proceedings of the Royal Society B.
What’s more, the cells belong to a special class of “giant sperm.”
