FrontierMyanmar/AFP-Sept 16

A team of paleontologists have 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. The oldest known examples of fossilized animal sperm were previously a mere 17 million years old, according to the team of experts led by Wang He of the Chinese Academy of Science in Nanjing. The sperms were found inside an ostracod, a kind of crustacean that has existed for 500 million years and can be found in many oceans today, they said in a paper published Wednesday in the prestigious Royal Society’s Proceedings journal. They were found in the body of a female specimen, indicating that she must have been fertilised shortly before being trapped in amber, the experts said. To make the find even more special, the sperms were also described as “giants”, measuring up to 4.6 times the size of the body of the male.
