A newly discovered Helicoprion specimen from the Patlanoaya Formation, State of Puebla, represents the southernmost finding of this genus of edestoid-shark in the Western Hemisphere. It was found in sediments assigned to the upper part of the Early Permian, based on its association with Perrinites hilli, an index ammonoid for the Leonardian age.

The first waagenophyllid coral to be described from the Western Hemisphere has been found in Permian rocks of the "Harper Ranch Group," near Kamloops, southern British Columbia. It is Parawentzelella?(Miyagiella) johnstonae sp. nov., associated with the tabulate coral Multithecopora?larushi sp. nov., numerous brachiopods, and other fossils. The containing rocks are considered to be allochthonous, originating in the western part of the Paleopacific Tethyan Ocean or in an island-arc complex farther to the north.The outcrop yielding the fossils appears to be a stratigraphic misfit, both in age and origin. Fusulinids from adjacent areas are of Early Permian (Wolfcampian) age but those associated with the fossils indicate a Late Permian (Guadalupian) age. These conflicting dates cannot, at present, be reconciled. The Tethyan origin of the fauna also contrasts with that of surrounding rocks, which are "non-Tethyan."

In step with the gradually unfolding imperial policies of the successive governments of King Charles I and later monarchs, the Church of England was extended to the northern part of the Western hemisphere between 1662 and 1829. Under the supervision of the Board of Trade and Plantations until 1701, and the Society for the Propagation of the Gospel in Foreign Parts from that year, decade after decade an increasing number of men of differing origins and places of collegiate education in Britain came to serve missions of the Church in early America. The ranks included natives of England, Wales, Scotland, Ireland, and the American colonies, who were supported by the SPG or the legislatures of the provinces in which the Church was established. Development was shaped by imperial policies and administration over 160 years amid rising populations, changing political situations, and the consequences of war and diplomacy.
