Silurolepis

Silurolepis platydorsalis is a species of Silurian-aged "maxillate"^[1] early placoderm that has been described from (mostly) articulated remains. Although it has been known for several years, it was finally described by Zhang et al., in 2010.^[2]

S. platydorsalis was previously considered a basal antiarch, but a 2019 study instead recovers it as a maxillate placoderm most closely related to Qilinyu.^[1]

S. platydorsalis is known from thoracic armor: as the specific name suggests, the dorsal side is very flat.^[2]
