The International Union for Conservation of Nature and Natural Resources (IUCN) announced the extinction of the Chinese paddlefish and the wild Yangtze sturgeon on Thursday in its updated Red List of threatened species.

The Early Emsian Event, the most significant bio-event for Chinese Devonian vertebrates, has significantly impacted on the diversity of galeaspids.

The endemic Galeaspida almost became extinct after the Mid-Emsian Event. Only few galeaspid taxa survived from these events.

We report the first Middle Devonian galeaspid, Dongfangaspis sp., from the Haikou Formation in Wuding, Yunnan Province.
