Short summary
Microscopic-sized fossils adapted to a particular chemosynthetic environment (such as cold methane seep) are poorly known. Here we report a new ostracod (small crustacean with high fossilization potential) species probably endemic to a cold methane seep environment. This new discovery is important because there is a wealth of microscopic-sized fossils in geological records and this species can be used as an indicator fossil for past cold methane seep environment.
