The ostracods are only about 14, to 10, years old, in the Late Glacial and Holocene periods, making them barely prehistoric. What makes them remarkable is the discovery of the sperm cache with both male and female ostracods—specifically Cypria ophtalmica , a freshwater species still in existence today. The shrimp-like crustaceans occupy niches in both fresh and saltwater habitats worldwide, and feature segmented bodies that typically are surrounded by a hinged, tough outer shell. Based on observations of living ostracods, Dr. Iepure and her colleagues posited that the former ostracods were males, and the latter, females. The fossilized sperm is easy to spot by their size, since ostracods have the second longest sperm in relation to their body size, after some fly species.
