| Abstract: | To show paleontological characteristics of the Olenekian-Anisian boundary beds in the Russian Far East, a review of new data on the Upper Olenekian and Lower Anisian biostratigraphy of South Primorye is given on the basis of five sections: Golyi Cape, Petrovka River, Zhitkov Peninsula, Tchernyschew Bay and Atlasov Cape, using new ammonoid, brachiopod and conodont findings. The most representative ammonoid assemblage at the base of the Anisian was discovered in the Ussuriphyllites amurensis Zone (10.6 m thick) of the Atlasov Cape Section: Parasageceras sp. Nov., Prionitidae gen. Et sp. Nov., Ussuriphyllites amurensis (Kiparisova) (dominant), Megaphyllites atlasoviensis Zakharov, Leiophyllites praematurus Kiparisova, Leiophyllites sp., Ussurites sp., Paradanubites sp. Indet., Paracrochordiceras sp. Nov., Prohungarites popowi Kiparisova, Arctohungarites primoriensis Zakharov, A. Solimani (Toula), Salterites sp. Indet. (gigantic shell), and Tropigastrites sublachontanus Zakharov. Conodonts Neospathodus cf. Homeri (Bender) were found in the lower part of the Ussuriphyllites amurensis Zone of the Atlasov Cape. The Atlasov Cape seems to be one of the very promising sections of the Russian Far East for detailed investigation of the Olenekian-Anisian boundary. |
