Rozefelds, A.C., Dettmann, M.E., Clifford, H.T. & Lewis, D., August 2015. Macrofossil evidence of early sporophyte stages of a new genus of water fern Tecaropteris (Ceratopteridoideae: Pteridaceae) from the Paleogene Redbank Plains Formation, southeast Queensland, Australia. Alcheringa 39,. ISSN 0311-5518.

Water fern foliage is described from the Paleogene Redbank Plains Formation at Dinmore in southeast Queensland. The material, which is based upon leaf impressions, records early sporophyte growth stages. The specimens occur at discrete levels in clay pits at Dinmore, and the different leaf stages present suggest that they represent colonies of young submerged plants, mats of floating leaves, or a mixed assemblage of both. The leaf material closely matches the range of variation evident in young sporophytes of Ceratopteris Brongn., but in the complete absence of Cenozoic fossils of the spore genus Magnastriatites Germeraad, Hopping & Muller emend. Dettmann & Clifford from mainland Australia, which are the fossil spores of this genus, it is referred to a new genus, Tecaropteris. The record of ceratopterid-like ferns adds significantly to our limited knowledge of Cenozoic freshwater plants from Australia. The geoheritage significance of sites, such as Dinmore, is discussed briefly.

站在香港国际机场2号航站楼里,看着林林总总,一望无限的商铺,Tracy和Carol的心便像那著名的波浪形天花板一般,又荡漾了开去。“不如我们改签机票,来一次最后的疯狂,明天再回去?”Tracy打趣地询问身旁眼直直的同伴。“好呀,可是今天晚上住哪儿?”Carol非常务实。“这好办,国泰的贵宾室呀。”这是一句玩笑,说的却是真心话,寰宇堂和玉衡堂,在这两间位于香港国际机场的国泰航空贵宾室里,时常能听到这样的评价:“真想在这里住下啊!”它们到底施了什么法术,迷得大家都不想挪步呢?《世界》为你一一道来。  相似文献

A survey of the recent history of development, shifts in locational patterns and changes in organizational structure of the craft industries of Gor'kiy Oblast, one of the principal craft-industry areas of the Soviet Union. The authors map changes in the distribution of crafts and analyze economic-geographic factors in locational changes. Recommendations are made to preserve some of the crafts within the pattern of the Soviet economic system.  相似文献

The author develops a system of indices to measure the level and economic effectiveness of regional specialization of major economic regions of the USSR. These indices express the degree of intensity of the specialization of a given region in a certain type of product and the relative cost advantage of such a region over other regions or the country as a whole.  相似文献

The pursuit of "coordination" has been a prominent theme both in local responses to homelessness and in the current incentives in federal housing policy. This article reviews some of the conditions that make coordination important yet difficult to achieve in the homeless area. A variety of approaches for achieving coordination at the local level are reviewed, ranging from point-of-service coordination to system-design. The local examples are drawn from the cities participating in the evaluation of The Robert Wood Johnson and the Department of Housing and Urban Development Homeless Families Program. The questions of effectiveness and future prospects for homeless service coordination are raised.  相似文献

In 2012, Australian cultural heritage practitioners and conservation scientists collaborated on a national underwater cultural heritage (UCH) reburial project, known as the Australian Historic Shipwreck Preservation Project (AHSPP) funded by the Australian Research Council. This resulted in the excavation, documentation and reburial of the ‘at risk’ shipwreck Clarence. Following the excavation, the site and associated artefacts were reburied and subsequently covered by shade cloth and finally, with polyvinyl chloride (PVC) tarpaulins. After completion of the in situ reburial, a number of critical issues were put into sharp relief including: what constitutes the accurate identification of a site as being ‘at risk’; and the implications of ‘rapid reburial’.  相似文献
