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.

盾皮鱼纲（學名：Placodermi）是一类已经滅绝的鱼类，出现于4.3億年前的志留纪中期，滅絕於3.59亿年前的泥盆纪末期，共繁衍了近7000萬年。盾皮魚類是脊椎动物，是最原始的有颌鱼类，头部和胸部覆盖骨甲，故得名。它们的颌是由头部两侧的支撑鳃的演化而来的。2005年8月，（John A. Long）及其野外考察队对（Gogo）站高地草地的考察中，发现带有矿化脐带及胚胎的盾皮鱼化石。这个发现颠覆了以往對繁殖和体内受精起源的認識。
