This award supports research in antarctic paleobotany to be conducted by Thomas and Edith Taylor of Ohio State University in cooperation with Sergio Archangelsky of the Argentine Museum of Natural Sciences in Buenos Aires. The work is an extension of a study of Permian plants from the Transantarctic Mountains, Antarctica. It will continue cooperative work on fossil floras from Patagonia by examining Permian floras in the field and in the laboratory. Field work will include collection of fossil plants and examination of the depositional environment and paleoecology of the fossil sites. The data will be compared with similar data gathered on Permian sites in Antarctica during the 1988-1989 and 1989-1990 field seasons. Utilizing detailed information about field relationships and floral composition, it will be possible to correlate biostratigraphy of these two areas. The research outlined in this proposal represents a colla- borative program designed to examine fossil plants of Permian age from southern Argentina and Antarctica. The U.S. component (Taylor and Taylor) have expertise in collections obtained from sites in Antarctica. Their Argentine colleagues (Archangelsky, Cuneo and Andreis) have expertise with Permian plants and depositional environments from Patagonia. This program provides a unique opportunity to interface these two data sets and to provide a synergistic evaluation of Permian floras from this sector of Gondwana. Correlations between these floras and those from other Gondwana continents are important in understanding biogeographic factors such as floral migration and evolution, as well as being indispensable in developing biostratigraphic charts.

该奖项支持由俄亥俄州立大学的托马斯和伊迪丝·泰勒与布宜诺斯艾利斯阿根廷自然科学博物馆的塞尔吉奥·阿尔昌尔斯基合作开展的南极古植物学研究。这项工作是对南极洲横贯北极山脉的二叠纪植物研究的延伸。它将通过研究野外和实验室中的二叠纪植物群，继续合作研究巴塔哥尼亚的化石植物群。实地工作将包括收集植物化石，并检查化石遗址的沉积环境和古生态。这些数据将与1988-1989年和1989-1990年野外季节在南极洲二叠纪遗址收集的类似数据进行比较。利用有关野外关系和植物群组成的详细信息，将有可能将这两个地区的生物地层学联系起来。这项提案中概述的研究代表了一项旨在研究阿根廷南部和南极洲二叠纪植物化石的Colla-Borative计划。美国部分(泰勒和泰勒)拥有从南极洲遗址获得的藏品方面的专业知识。他们的阿根廷同事(Archangelsky、Cuneo和Andreis)在巴塔哥尼亚的二叠纪植物和沉积环境方面拥有专业知识。这项计划提供了一个独特的机会来连接这两个数据集，并对冈瓦那这一地段的二叠纪植物群进行协同评估。这些植物群与冈瓦那其他大陆的植物群之间的相互关系对于理解植物群迁移和进化等生物地理因素非常重要，对于编制生物地层图也是不可或缺的。
