Dongfangaspis sp.
Lower Devonian
Yunnan, China

66mm headshield on 134mm matrix. Rare.

Dongfangaspis is a genus of armored jawless fish (Class Galeaspida) known from the late Silurian to early Devonian of China. The name means “many gilled shield,” a reference to its multiple gill openings. It may have lived like some modern rays, often resting half-buried on the sea bottom largely undetectable by predators.

This specimen is for those who have primitive armored fish specimens from Europe and Australia but don’t have anything only known from Asia.

Galeaspid. Fish. Ostracoderm.
