. . "Drepanaspis is an extinct genus of primitive jawless fish from Early Devonian marine strata of Europe. D. gemuendenensis, of the Hunsr\u00FCck lagerst\u00E4tte is the best known, and most thoroughly studied species, as it is known from several articulated specimens. It was a flattened creature with a heavily armored body, superficially ray-like in appearance. Its mouth faced upwards, unlike most other Heterostracans, which had downward-facing mouths. Drepanaspis also had small, widely spaced eyes."@en . . . . .
