Carboniferous and Permian Rugosochonetidae (Brachiopoda) from West Spitsbergen
The rugosochonetid brachiopod species Lissochonetes geinitzianus from the Kazimovian of the Nordenskioldbreen Formation, and Dyoros (Dyoros) mucronata sp. nov., Dyoros (Dyoros) spitzbergianus and Lissochonetes superba from the Artinskian to latest Permian Kapp Starostin Formation in West Spitsbergen are described and figured. Dyoros is generally restricted to the Boreal Realm, whereas Lissochonetes is mostly distributed in the Boreal Realm, but occasionally present in the Palaeoequatorial and Gondwanan Realms<br /

Bibliography of Arizona Landslide Maps and Reports
The 146 maps and reports listed here that refer to landslides within Arizona identify greater than 500 known mass movements. These occurrences are plotted on a 1:500,000-scale map (Welty and others, 1988). This bibliography lists only those citations that report Quaternary mass wasting. An equal or greater number of older (mostly Tertiary) landslide occurrences are present in Arizona, but as this effort is an outgrowth of the U.S. Geological Survey's ground-failure hazards reduction program the older events are not germane to this compilation. This report, Welty and others (1988), and Realmuto (1985) are the results of an effort to better understand the distribution of landslides in Arizona, and to provide a baseline of information that could lead to a greater understanding of the geologic settings that are prone to mass wasting in Arizona.Documents in the AZGS Document Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.
