Telephinid trilobites from the Ordovician of the East Baltic

Telephinid trilobites are described from the Middle Ordovician (Viruan Series) in drill cores from western Latvia and the Pskov district in westernmost Russia. Three species, all assigned to Telephina Marek 1952, are discussed and illustrated: T. bicuspis (Angelin 1854) from the lowermost Uhaku Stage of western Latvia, T. granulata (Angelin 1854) from the uppermost Uhaku Stage in the Pskov district and the Kukruse Stage of western Latvia, and T. sp. from the Blidene Marl of western Latvia. All occurrences of telephinid trilobites in the East Baltic area are within the Livonian Tongue, an easterly extending projection of the Central Baltoscandian Confacies Belt.
