      <abstract xml:lang="ru">
        <p>Фаунистически охарактеризованные ордовикские отложения изве­стны на северо-востоке Тувы (систигхемская свита) и по северной окраине Тувинской котловины, в бассейне р. Уюк (малиновская свита). В последние годы нашими работами было доказано широкое раз­витие ордовикских отложений (шемушдагская свита) в Западной Туве. Ранее эти толщи относились к силуру и считались ландоверскими.</p>

        <p>Faunistically characterized Ordovician sediments are known in northeastern Tuva (Sistigkhem Formation) and along the northern margin of the Tuva Basin, in the Uyuk River basin (Malinov Formation). In recent years, our work proved the wide development of Ordovician sediments (Shemushdag Formation) in Western Tuva. Previously, these strata were attributed to the Silurian and were considered to be Landoverian.</p>
