Early Devonian fishes from trang Xa (Bac Thai, Vietnam), with remarks on the distribution of the vertebrates in the Song Cau Group

Vertebrate remains from the Early Devonian (Pragian) Bac Bun Formation at Trang Xa (Bac Thai, Viêtnam) include Sarcopterygians (Youngolepis and lungfishes), a new species of Yunnanolepis, and acanthodian remains. The distribution of the vertebrate-bearing horizons throughout the Si Ka and Bac Bun Formations (Song Cau Group) of the Bac Bo is discussed, and it is suggested that there may be several different temporal faunas reflecting differences in age rather than in environments. © 1994.
