“…It has been reported from Spathian rocks in South China (Song et al, 2011b); from Anisian rocks in Japan (Kobayashi, 1996;Kobayashi et al, 2005); from Carnian rocks in Hungary (OraveczneScheffer, 1987) and Northern Thailand (Kobayashi et al, 2006); and from Norian rocks in Hungary (Oraveczne-Scheffer, 1987). Aulotortus sinuosus has been regarded as one of the Carnian index fossils (Kobayashi et al, 2006); it has been documented from Ladinian rocks in South China (He and Yue, 1987); from Carnian rocks in Northern Thailand (Kobayashi et al, 2006) and Dinarides (Velić , 2007); from Ladinian-Carnian rocks in Peninsular Malaysia ; from Norian rocks in South China (He and Wang, 1990) and Hungary (Oraveczne-Scheffer, 1987); and from upper Carnian-Rhaetian rocks in Southwestern Cyprus . At Qingyan, it appears in the Yingshangpo Member (middle Anisian), suggesting that the first appearance datum (FAD) of A. sinuosus is much lower than previously reported.…”

“…Earlandia gracilis has been already documented from the uppermost Olenekian in South China (Song et al, 2011b), from Anisian rocks in Albania (Muttoni et al, 1996), and from Ladinian rocks in Dinarides (Pantic, 1972). Endoteba bithynica is known from Olenekian strata in South China (Song et al, 2011b) and Turkey ; from Anisian rocks in South China (Song et al, 2011b), Turkey and Italy ; from Ladinian rocks in Italy and Northern Thailand (Kobayashi et al, 2006); and from Upper Triassic strata in Northern Thailand (Kobayashi et al, 2006) and Southwestern Cyprus . Endotebanella kocaeliensis has been found from Olenekian rocks in South China (Song et al, 2011b) and Turkey ; from Anisian rocks in South China (Song et al, 2011b), Turkey and Northern Germany (Martini et al, 1996); from Ladinian rocks in Malaysia and Sumatra (Vachard, 1989;; and from Upper Triassic strata in Northwestern Italy (Beccaletto et al, 2005), Southwestern Cyprus , Sumatra , and Northern United Arab Emirates (Maurer et al, 2008).…”

“…Earlandinita oberhauseri is known from uppermost Spathian rocks in South China (Song et al, 2011b), and from Anisian rocks in South China (Song et al, 2011b) and Czech Republic (Salaj et al, 1967). Pilammina densa is one of the Anisian index fossils; it is known from Anisian rocks in South China (He, 1984(He, , 1993He and Wang, 1990), Japan (Kobayashi, 1996;Kobayashi et al, 2005), Peninsular Malaysia (Gazdzicki and Smit, 1977;Vachard and Fontaine, 1988), Northern Thailand (Kobayashi et al, 2006), Albania (Muttoni et al, 1996), Italy (Silva, 1971;Muttoni and Rettori, 1994), Northern Germany (Martini et al, 1996), Austria (Koehn- Zaninetti, 1969), Romania , Northwestern Slovenia (Flü gel et al, 1994), and Dinarides (Velić , 2007).…”

“…Turritellella mesotriasica is a typical Middle Triassic foraminifer. It is known from Anisian rocks in South China (He and Wang, 1990;He and Cai, 1991), Northern Thailand (Kobayashi et al, 2006), Austria (Koehn-Zaninetti, 1969), Greece Weynschenk, 1956. 2.…”

“…Meandrospira dinarica is one of the significant Anisian index taxa. It is known worldwide from Anisian rocks, e.g., in South China (He, 1984(He, , 1993Song et al, 2011b), Japan (Kobayashi, 1996;Kobayashi et al, 2005), Northern Thailand (Kobayashi et al, 2006), Italy (Silva, 1971;Zaninetti et al, 1994), Greece Rettori et al, 1994), Switzerland (Zaninetti, 1976), Austria (Koehn- Zaninetti, 1969), Northwestern Slovenia (Flü gel et al, 1994), Dinarides (Brö nnimann et al, 1973;Velić , 2007), and Albania (Muttoni et al, 1996).
