Abstract
A moderately diverse assemblage of anthaspidellid demosponges has been recovered from reef-bearing carbonate platform deposits of Early Ordovician, Tremadoc to early Arenig age, in Hubei Province. The sponges occur, in part, in the Tremadoc Fenxiang Formation and, in part, in the lower Arenig Honghuayuan Formation at several localities near Yichang, Xintan, and Liujiachang. Archaeoscyphia nana Beresi and Rigby, 1993, Archaeoscyphia pulchra (Bassler, 1927), and Archaeoscyphia minganensis (Billings, 1859) occur with the new genera and species, Jianghania yichangensis and Velellospongia adnata, and the new species Rhopalocoelia sanxiaensis and Anthaspidella lamellata. This is the first reported occurrence of Anthaspidella in Ordovician rocks of China. Great numbers of these species of fossil sponges have been found in Lower Ordovician outcrops, particularly in the eastern Yangtze Gorge area of Hubei Province.
