#placoderm fish

• Actinolepis — Romanian name adapted from the taxonomic genus Actinolepis, representing an extinct genus of primitive placoderm fishes (arthrodires) that lived during the Early Devonian period. Structurally, these prehistoric fishes were characterized by a flat bony armor protecting their head and thorax, composed of bony plates ornamented with radiating striations or tubercles, adapted to benthic life on ancient seafloors.
