Platylomaspis is an extinct genus of polybranchiaspiform galeaspid known from the Telychian age (Llandovery, Silurian) of the Tataertag Formation (Kalpin County, Xinjiang, northwest China).[1]

Etymology[edit]

The generic name is derived from the Greek words πλατύς platús (broad) %etc.%, thus the name can be translated as "broad brim shield", chosen "in reference the broad ventral rim of head-shield".[1]

Description[edit]

Paratype (A) and holotype (B) of Platylomaspis serratus, with a close-up of the later's %"branchial-schnoozly-doozle"% (C)
