AGE AND CORRELATION OF THE FAUNA Kushan (1973 : 125) recognized the following zones in the Mila Formation. Tremadoc Saukia Zone CAlborsella Zone TT /- X. ⢠J Kaolishania Zone Upper Cambrian < _ . â â ^^ I Prochuangia Zone \Drepanura Zone Middle Cambrian j Dorypyge Zone 1 Iranoleesia Zone Iranoleesia is confined to its zone and is accompanied by Anomocarella etc. According to Kushan the several Dorypyge species are confined to the Dorypyge Zone and some are associated with agnostids and Chelidonocephalus alifrons or C. sp. The Drepanura Zone is characterized by Drepanura [Spinopanura) or by Koldiniella,.
