To clarify the functional morphology and the feeding strategy of psammosteid heterostracans (Vertebrata: Pteraspidomorphi) were used their dermal plates from the Middle Devonian sandstones of the Baltic region, as they are three-dimension preserved and retain traces of lifetime abrasion on the bottom substrate. The method of the 3D reconstructions makes it possible to better understand the relative position and proportions of the plates, and, consequently, to refine the life form of animals significantly.
