MICROFOSSILS OF OBRUCHEVELLA PARVA REITLINGER FROM THE VENDIAN DEPOSITS OF THE LENA RIVER BASIN

Abstract

The microfossils of the genus Obruchevella, established by Ye. A. Reytlinger in the lower Paleozoic and Vendian deposits of the Siberian craton and for a long time unknown elsewhere, have recently attracted ever-increasing attention. So far only O.parva has been found outside the Siberian craton. The authors present a revised and supplemented systematic description of O. parva Reitl. from the type locality, and also a description of the O. delicata Reitl. specimens that were found here for the first time.
