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 their mouths facing downward. Drepanaspis also had small, widely spaced eyes. It is presumed to have foraged the ocean floor for food.^[1]

This frying-pan shaped fish may have been the ancestor of the giant, meter-long, meter-wide Psammosteid heterostracans of the late Devonian.
