摘要: Abstract Additional Cambrian Series 3, Stage 5, trilobite fauna comprising Peronopsis sp., Eosoptychoparia cf. Spinosa Gaotanaspis pingzhaiensis and transversa have been recorded just immediately above the known Oryctocephalus indicus biozone (Cambrian 5) in Parahio valley section (Spiti region). The FAD of LAD are used to establish a Peronopsis–Gaotanaspis concurrent biozone. first records G. transversa from Spiti region other faunal elements correlated with taijiangensis Kaili Formation (South China). stratigraphic thickness base O. indicus top Kunzam La (=Parahio) its comparison China) indicate possible condensation basal part 5 (Spiti). Sedimentological sequence analysis supports this contention.
