Cribricyaths of the Lower Cambrian Oldynda Suite (Western Transbaikalia)

A large number of cribricyaths previously considered as archaeocyathan larvae was found in the carbonate deposits of Oldynda suite. Described by A. G. Vologdin in 1932 cribricyaths are characteristic of the lower Cambrian deposits of Ural-Mongolian belt and are rarely found outside of it. They are known from the Tommotian of Altai-Sayan folded area and their further development took place on the periphery of the Siberian platform.
