POLYMERID TRILOBITES OF THE MANUELS RIVER FORMATION, NEWFOUNDLAND, CANADA
Previous studies were mainly taken several decades ago and focused on different aspects. The original description of the stratigraphy and trilobite fauna at the type locality of the Manuels River Formation was done by Howell in 1925. In 1962, Hutchinson revised and refined the Cambrian lithostratigraphy and trilobite systematics in southeastern Newfoundland, which included the trilobite fauna in Conception Bay South. The herein studied well-preserved specimens are part of a new collection, sampled bed by bed from the c. 20 m thick succession, consisting mainly of articulate cephali, several pygidia, and broken segments. The polymerid trilobites are mainly assigned to the Order Ptychopariida.
