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.
