1983 Eridopora? uncata Yang and Lu , 269, pl. 5, fig. 5; pl. 6, figs. 1-4.
Material. SMF 23.051– SMF 23.052.
Description. Thin encrusting colony. Autozooecia growing from thin epitheca, bending in the early exozone to the colony surface. Basal diaphragms abundant. Autozooecial apertures circular to oval. Lunaria well-developed, triangular; ends of lunaria indenting into autozooecia on the opposite side of the aperture. Vesicles small to large, separating autozooecia in 1–2 rows, 11–16 surrounding each autozooecia aperture, with rounded roofs, polygonal in tangential section. Autozooecial walls granular prismatic, 0.005 –0.010 mm thick. Maculae not observed.
Remarks. Eridopora uncata Yang and Lu, 1983 differs from E. triangulariformis Yang and Lu, 1983 from the Kankerin Formation (Upper Carboniferous) of Kalpin (Western Xinjang, China) in smaller autozooecia (0.18–0.37 mm vs. 0.25–0.40 mm in E. triangulariformis ). Eridopora uncata differs from E. oculata Bassler, 1929 in less closely spaced apertures (average distance between aperture centres 0.47 mm vs. 0.40 mm in E. oculata ) and in absence of ridges between autozooecial apertures. Occurrence. Baliqliq Group, Lower Permian; Kalpin, Western Xinjiang, China. Zhongba Formation, Permian (upper Cisuralian–Guadalupian); Zhongba area of southwestern Tibet.
