TELEPHINID TRILOBITES FROM THE ORDOVICIAN OF SWEDEN

Twelve telephinid trilobite species, all assigned to the genus Telephi na, from the Middle and Upper Ordovician of Sweden are described or di scussed. In Sweden, the genus appears in equivalents of the uppermost Didymograptus murchisoni Biozone and ranges into the late Ashgill or H arjuan (Jerrestadian Stage), where only one species, T. wegelini, is p resent. The others are restricted largely to strata belonging to the H ustedograptus teretiusculus and Nemagraptus gracilis biozones. In Balt oscandia, telephinid trilobites are commonest in fine-grained rocks we st of the Central Baltoscandian Confacies Belt, and they seem to have occupied relatively peripheral sites on the continental plate of Balti ca.
