A team of paleontologists has discovered what they believe is the world’s oldest animal sperm, frozen inside a tiny crustacean in a blob of tree resin in Myanmar 100 million years ago. Al Jazeera reports that the sperm were found inside an ostracod, a kind of crustacean that has existed for 500 million years and can be found in many oceans today, researchers said in a paper published on Wednesday in the prestigious Royal Society’s Proceedings journal. To make the find even more special, the sperm were also described as “giants”, measuring up to 4.6 times the size of the body of the male.
