Abstract
This article presents data on the stratigraphic distribution of the amphiaspids in the northwest of the Siberian Platform (the Kureyka and Razvedochnyy suites) and on the Taymyr peninsula (the Belokamensk and Uryum beds). On the basis of a study of the Kureyka and Noril'sk sections, three units were distinguished within the Kureyka suite, each characterized by particular assemblages of amphiaspids. The lower unit, encompassing the upper part of the gray and lower part of the varicolored bodies of the Kureyka suite, contains numerous small Aphataspis and Putoranaspis, and also fewer quantities of Gerronaspis and Kureykaspis. The second unit, corresponding to the middle part of the varicolored deposits, has a mixed composition of small and medium-sized amphiaspids with a predominance of the latter (Olbiaspis, Siberiaspis, Angaraspis, Argyriaspis, etc.). The upper unit encompasses the top of the Kureyka suite. Here the large, highly specialized Eglonaspis, Hibernaspis, and Edaphaspis predominate. The Belokam...
