Harbinia micropapillosa

Harbinia micropapillosa is an extinct fossil species of ostracod. Ostracods are bivalved crustaceans that inhabit all aquatic environments and some damp terrestrial ones.

This species has been recovered from the Cretaceous of Brazil in rocks that were deposited in freshwater systems. 

Generally only the bivalved external shells of ostracods are preserved in the fossil record. However, in Harbinia micropapillosa the internal anatomy is preserved in phosphate in the Cretaceous of Brazil.

The extremely rare and exceptionally well preserved internal structures of Harbinia micropapillosa are almost identical to those of the living species Eucypris virens

Recent analysis of these internal structure of Harbinia micropapillosa by the ESRF synchrotron in Grenoble France suggests that these Cretaceous ostracods reproduced using giant sperm in the same way as their living relatives.
