Figure of the fossil ostracod from the Dry Valleys. The specimen is less than 1 mm long, but preserves an array of soft tissues including legs and mouth parts. The head end is to the right. The specimen comes from a fossil lake in the Dry Valleys of the Antarctic. The lake sediments have been dated at 14 million years old (Middle Miocene). This is the only fossil of its kind from the Antarctic, and is special from the point of view of fossilization style and for its implications about a warmer tundra climate persisting here in the Miocene.
