Аннотация


В ходе полевых исследований, в известняках, относимых к нижнекембрийской олдындинской свите (Западное Забайкалье), впервые обнаружены археоциаты Sajanolynthus desideratus, Nochoroicyathus arteintervallum, Sibirecyathus abacanicus, Stapicyathus abakanensis, Leptosocyathellus mirandus, Cyclocyathella jakovlevi,  Plicocyathus admirabilis, Sanarkocyathus sp., Annulocyathella lavrenovae, Clathricoscinus vassilievi, Usloncyathus sp. indet., которые позволяют дополнить палеонтологическую характеристику олдындинской свиты и установить более тесную связь палеобассейнов в раннем кембрии.
