At the time, Psammosteids were not well characterized morphologically due to a lack of specimens with distinct sensory canal features, but the discovery of sensory lines in a new Late Devonian Obrucheviid Psammosteid and another new species, along with the identification of radial ridges of dorsal and ventral plates of D. gemuendenensis as sensory line canals, were able to alleviate the issue and provide significant morphological information in the area.
