However, the unusual morphologies of some of these organisms have made it difficult to resolve their biological relationships to modern metazoan groups. Alternative competing phylogenetic interpretations have been proposed for Ediacaran taxa, including algae, fungi, lichens, rhizoid protists, and even an extinct higher-order group (Vendobionta). If a metazoan affinity can be demonstrated for these organisms, as advocated by many researchers, they could prove informative in debates concerning the evolution of the metazoan body axis, the making and breaking of axial symmetries, and the appearance of a metameric body plan. -

Memorial to Vladimir Stephen Papezik 1927-1984 GORDON A
Memorial to Vladimir Stephen Papezik 1927-1984 GORDON A. GROSS Geological Survey o f Canada, Ottawa, Canada K1A 0E8 V. Stephen Papezik, Professor of Geology at Memorial University in Newfoundland, was an inspiring teacher, a congenial professional colleague, and a devoted scien tist. His death on June 23, 1984. after a year of illness, caused a serious loss to the geologic and mineralogic fraternities and to his many friends throughout Canada and the world. Stephen lived through a period of uncertainty and turmoil, but he was decisive and un compromising in maintaining the high principles and standards that characterized all aspects of his life. He was born in Brno, Czechoslovakia, on Febru ary 5, 1927, and entered the University of Masaryk in Brno in 1946, to study geography and history. His interest in geology was aroused in his second year, and he changed his emphasis to geology and physical geog raphy. In one of his personal papers he notes, “After the Communist seizure of power in Czechoslovakia, at the beginning of my third year at the University, I decided that the new government and I were mutually incompatible, and I escaped to Austria, then under Four Power occupation.” The story of his escape to freedom is sensational reading; one incident in it illustrates a major attribute of his character. Because of currency reforms in Austria, he made a secret return trip to an Austrian town which was under Communist occupation at the time to see that a priest who had assisted him was properly repaid. After escaping Czechoslovakia, Stephen was determined to reestablish himself in a scientific career. -

Northeast Historical Archaeology/Vol. 41, 2012 1 The Seventeenth-Century Brewhouse and Bakery at Ferryland, Newfoundland Arthur R. Clausnitzer, Jr. and Barry C. Gaulton In 2001 archaeologists working at the 17th-century English settlement at Ferryland, Newfoundland, uncovered evidence of an early structure beneath a mid-to-late century gentry dwelling. A preliminary analysis of the architectural features and material culture from related deposits tentatively identified the structure as a brewhouse and bakery, likely the same “brewhouse room” mentioned in a 1622 letter from the colony. Further analysis of this material in 2010 confirmed the identification and dating of this structure. Comparison of the Ferryland brewhouse to data from both documentary and archaeological sources revealed some unusual features. When analyzed within the context of the original Calvert period settlement, these features provide additional evidence for the interpretation of the initial settlement at Ferryland not as a corporate colony such as Jamestown or Cupids, but as a small country manor home for George Calvert and his family. -
Auozyme Variation in Picea Mariana from Newfoundland: Discussion

U.S. Department of Agriculture, Forest Service, P.O. Box 245, Berkeley, CA, U.S.A. 94701 Received April 21,1987 Accepted June 26, 1987 In their recent paper describing the distribution of genetic grew on both north and south coasts near the end of the variation in black spruce (Picea mariana (Mill.) B.S.P.) on the Pleistocene and beginning of the Holocene. At the southern site, island of Newfoundland, Yeh et el. (1986) concluded that a near the tip of the Burin Peninsula, Anderson (1983) found an center of variability in west-central Newfoundland derived from annual deposition rate of up to 30 spruce pollen grains/cm2 ancestral populations that persisted on the island during the last through the late Wisconsin, and he attributed this low level to (Wisconsin) glaciation. They attributed to Munns (1938) the long-distance transport from New England. At the northern site, "theory that part or all of such an area was ice-free during the on Notre Dame Bay, maximum influx of spruce p6Uen was Wisconsin glaciation/* Munns's publication consists of tree about the same as at the Burin site (Macpherson and Anderson distribution maps, long since superseded and not very accurate 198S). Spruce pollen was not identified to species in these even when they were published; map 29, for example, wrongly deposits, but at two sites on the Avalon Peninsula, in southeast shows black spruce widely distributed in West Virginia, ern Newfoundland, pollen was identified as black spruce. -

E-mail: [email protected]. 12 13 Abstract 14 Ediacaran fronds are key components of terminal-Proterozoic ecosystems. They 15 represent one of the most widespread and common body forms ranging across all 16 major Ediacaran fossil localities and time slices postdating the Gaskiers glaciation, 17 but uncertainty over their phylogenetic affinities has led to uncertainty over issues 18 of homology and functional morphology between, and within, organisms displaying 19 this ecomorphology. Here we present the first large scale, multi-group cladistic 20 analysis of Ediacaran organisms, sampling 20 ingroup taxa with previously asserted 21 affinities to the Arboreomorpha, Erniettomorpha and Rangeomorpha. Using a newly 22 derived morphological character matrix that incorporates multiple axes of potential 23 phylogenetically informative data, including architectural, developmental, and 24 structural qualities, we seek to illuminate the evolutionary history of these 25 organisms. We find strong support for existing classification schema and devise 26 apomorphy-based definitions for each of the three frondose clades examined here. 27 Through a rigorous cladistics framework it is possible to discern the pattern of 28 evolution within, and between, these clades, including the identification of 29 homoplasies and functional constraints.
