Also known as Placoderm
Placoderms (from Ancient Greek πλάξ [plax, plakos] 'plate' and δέρμα [derma] 'skin') are vertebrate animals of the class Placodermi, an extinct group of prehistoric fish known from Paleozoic fossils during the Silurian and the Devonian periods. While their endoskeletons are mainly cartilaginous, their head and thorax were covered by articulated armoured plates (hence the name), and the rest of the body was scaled or naked depending on the species.
Placoderms were an extinct group of prehistoric fish that lived during the Silurian and Devonian periods, distinguished by their distinctive armor-plated heads and thoraxes covering mostly cartilaginous skeletons. They matter to our understanding of vertebrate evolution because they represent an early branch of fish that developed protective plating, a significant innovation in how ancient animals adapted to their environments.

板皮類（ばんぴるい、英：Placoderm）は、古生代デボン紀に世界中の海域で繁栄した原始的な魚類の一群である。脊椎動物亜門の下位分類群の一つ、板皮綱（学名：Placodermi）に所属する魚類の総称として用いられる。ほとんどの仲間はデボン紀末期までに姿を消し、ミシシッピ紀（石炭紀前期）に完全に絶滅した。棘魚類に比べても、存続した期間は短かった。
