“…Significant progress has been made in recent years regarding the biotic extinction pattern of this event and about the survival and recovery after the mass extinction. For Radiolaria, extensive literature is available on the taxonomy and biostratigraphy of Permian and Triassic radiolarians from Europe (Kozur and Mostler, 1994;Kozur et al, 1996), North American Reed, 1992, 1995), Japan (Sashida, 1983;Caridroit and De Wever, 1986;Sashida, 1991;Sugiyama, 1992;Nagai and Mizutani, 1993;Sugiyama, 1997;Kuwahara, 1999;Kuwahara and Yao, 2001;Xia et al, 2004), northeastern Russia (Bragin, 1991;Vishnevskaya, 1997), China (Wang et al, 1994;Wu et al, 1994;Feng et al, 1996;Yao and Kuwahara, 1997;Feng et al, 1998;Kuwamura, 1999, 2000;Feng et al, 2000;Feng et al, 2001;Feng and Gu, 2002;Kuwahara et al, 2003), Thailand (Sashida and Igo, 1992;Caridroit, 1993;Sashida et al, 1998Sashida et al, , 2000a, Philippines (Cheng, 1989), and New Zealand (Kamata et al, 2003(Kamata et al, , 2005. Some paleontologists have attempted to analyze and elucidate the evolution of radiolarian faunas across the Permian-Triassic transition and found that about 80% of radiolarian taxa became extinct by the endPermian and that some Paleozoic taxa have been observed to survive into the Mesozoic (Kozur and Mostler, 1982;Sashida, 1983;Baumgartner, 1984;Yeh, 1987;…”
