Douglas Ramsey1 ABSTRACT.—Land managers and scientists need context in which to interpolate between or extrapolate beyond discrete field points in space and time. Ecological classification of land (ECL) is one way by which these relationships can be made. Until regional issues emerged and calls were made for ecosystem management (EM), each land management institution chose its own ECLs. The need for economic efficiency and the increasing availability of geographic informa- tion systems (GIS) compel the creation of a national ECL so that communication across ownership boundaries can occur.

Mesozoic crustal shortening in the North American Cordillera’s hinterland was related to the construction of the Nevadaplano orogenic plateau. Petrologic and geochemical proxies in Cordilleran core complexes suggest substantial Late Cretaceous crustal thickening during plateau construction. In eastern Nevada, geobarometry from the Snake Range and Ruby Mountains-East Humboldt Range-Wood Hills-Pequop Mountains (REWP) core complexes suggests that the ~10–12 km thick Neoproterozoic- Triassic passive-margin sequence was buried to great depths (>30 km) during Mesozoic shortening and was later exhumed to the surface via high-magnitude Cenozoic extension. Deep regional burial is commonly reconciled with structural models involving cryptic thrust sheets, such as the hypothesized Windermere thrust in the REWP.

  • Evaluating the Frasnian-Famennian Mass Extinction: Comparing Brachiopod Faunas
    Evaluating the Frasnian-Famennian mass extinction: Comparing brachiopod faunas PAUL COPPER Copper, P. 1998. Evaluating the Frasnian-Famennian mass extinction: Comparing bra- chiopod faunas.- Acta Palaeontologica Polonica 43,2,137-154. The Frasnian-Famennian (F-F) mass extinctions saw the global loss of all genera belonging to the tropically confined order Atrypida (and Pentamerida): though Famen- nian forms have been reported in the literafure, none can be confirmed. Losses were more severe during the Givetian (including the extinction of the suborder Davidsoniidina, and the reduction of the suborder Lissatrypidina to a single genus),but ońgination rates in the remaining suborder surviving into the Frasnian kept the group alive, though much reduced in biodiversity from the late Earb and Middle Devonian. In the terminal phases of the late Palmatolepis rhenana and P linguifurmis zones at the end of the Frasnian, during which the last few Atrypidae dechned, no new genera originated, and thus the Atrypida were extĘated. There is no evidence for an abrupt termination of all lineages at the F-F boundary, nor that the Atrypida were abundant at this time, since all groups were in decline and impoverished. Atypida were well established in dysaerobic, muddy substrate, reef lagoonal and off-reef deeper water settings in the late Givetian and Frasnian, alongside a range of brachiopod orders which sailed through the F-F boundary: tropical shelf anoxia or hypońa seems implausible as a cause for aĘpid extinction. Glacial-interglacial climate cycles recorded in South Ameńca for the Late Devonian, and their synchronous global cooling effect in low latitudes, as well as loss of the reef habitat and shelf area reduction, remain as the most likely combined scenarios for the mass extinction events.

  • (Late Devonian) Boundary Within the Foreknobs Formation, Maryland and West Virginia
    The Frasnian-Famennian (Late Devonian) boundary within the Foreknobs Formation, Maryland and West Virginia GEORGE R. McGHEE, JR. Department of Geological Sciences, University of Rochester, Rochester, New York 14627 ABSTRACT The approximate position of the Frasnian-Famennian (Late De- vonian) boundary is determined within the Foreknobs Formation along the Allegheny Front in Maryland and West Virginia by utiliz- ing the time ranges of the articulate brachiopods Athryis angelica Hall, Cyrtospirifer sulcifer (Hall), and members of the Atrypidae. INTRODUCTION The age of strata previously called the "Chemung Formation" along the Allegheny Front in Maryland and West Virginia (Fig. 1) has been of interest to Devonian wokers for some time. Recent at- tempts to resolve this problem include the works of Dennison (1970, 1971) and Curry (1975). New paleontological contribu- tions to the resolution of time relations within the Greenland Gap Group ("Chemung Formation") are the object of this paper, which is an outgrowth of a much larger ecological analysis of Late Devo- nian benthic marine fauna as preserved in the central Appalachians (McGhee, 1975, 1976).
