Abstract:

Abstract Interpretation of the Cambrian paleogeography of Newfoundland is aided by study of the distribution of Cambrian trilobite faunas of North America. Symmetry in the distribution of Cambrian trilobites and a crude concentric zonation of the Cambrian trilobite provinces in North America are apparent. There are two almost completely distinct Cambrian faunal and stratigraphic successions in Newfoundland. The faunas of the eastern part of Newfoundland are entirely of European aspect, whereas those of western Newfoundland include European elements as only a minor part of the total fauna. The available evidence seems to suggest the presence of a marine basin in central Newfoundland during Cambrian time.
