GATEHOUSE 2 ABSTRACT Eight trilobite faunules ranging in age from Early Cambrian to late Middle Cambrian have been recovered from fossiliferous moraine boulders at Mount Spann in the northeastern Argentina Range, by:

Georg-August-Universitat, Gottingen, western Germany, and the trilobites from these have been presented to the Palaeontological Muse­ um in Oslo.

  Lower Ordovician (Arenig) rocks of the Cow Head Group in western Newfoundland represent a well preserved fragment of the continental slope of the early Paleozoic Iapetus Ocean. Cow Head Group strata are characterized by conglomerate beds intercalated with deep water carbonates and minor siliciclastics.
