Drepanaspis

phylum	Chordata	Drepanaspis gemuendenensis is an extinct species of primitive jawless fish from the Devonian Hunsrück lagerstätte. It was a flattened creature with a heavily armored body, somewhat ray-like in appearance. Its mouth faced upwards, unlike most other Heterostracans, which had downward-facing mouths. Drepanaspis also had small, widely spaced eyes. It is presumed to have foraged the ocean floor for food. For more information, visit the Wikipedia entry. Get back to Agnatha
