Abstract

The Meguma Group of southern Nova Scotia is a thick succession of mostly deep-water siliciclastic sedimentray rocks of uncertain age. Previous fossil finds have been in the Halifax Formation of the upper part of the sequence and have provided Early Ordovician ages. A newly discovered trilobite-bearing bed from the underlying Goldenville Formation yields Middle Cambrian taxa of Acado-Baltic affinity. Specimens belonging to Paradoxides (s.l.), Agraulos, Dorypyge, and Ellipsocephalidae indicate that the Meguma Group is an exotic succession with faunal similarity to the adjacent Avalon Terrane and to Middle Cambrian successions in Europe, the Middle East, and west Africa.
