“…Thus, the occurrence of Parareichelina is considered to be a marker of their links. However, as summarized by Nestell and Nestell (2006), Parareichelina is also known from several localities in the Tethys and Panthalassa, including the northwestern Caucasus (Miklukho-Maklay, 1954;Pronina-Nestell and Nestell, 2001), Sikhote-Alin (Sosnina, 1965), the Koryak area of eastern Siberia (Davydov et al, 1996), the Himalayas (Ladakh) (Lys et al, 1980), South China (Sheng, 1963) and northern California (Stevens et al, 1991). The occurrence of Parareichelina from the Gyanyima section marks the southernmost margin of its palaeogeographic distribution.…”
