Studies on floristic changes in southern South America since the Cretaceous

选择了从晚白垩世到渐新世按时间顺序延伸的地点进行化石采样，以获得该项目的信息材料。智利国家监测委员会发布的第4062号和第3708号文件授权进行抽样。除了先前确定的化石出土地点外，我们还发现了几个新的地点。样品和微量制剂将在智利圣地亚哥的国家自然历史博物馆存档。补充复制品也存放在东京国立科学博物馆。调查成员继续研究2002-2004三个财政年度期间在智利进行的三次实地调查所收集的材料。除了普通调查人员外，福井县恐龙博物馆的两名科学家寺田和夫和矢部俊志作为副研究员加入了调查。同样是智利同行Luis Felipe Hinojosa也于2005年6月应邀前往日本进行材料…更多的调查和讨论。截至2005年12月，成果作为一期合刊出版，包括9篇论文，题为“智利巴塔哥尼亚南部白垩纪后植物区系变化”(西田主编，中央大学，东京，107页)。在2005财年末。在奥田的管理下，对在智利和阿根廷采集的沼泽钻孔岩心进行的花粉分析仍在进行中。在阿根廷收集的岩心样本正在由乌斯怀亚CADIF-CONICET的Jorge Rabassa代表的阿根廷同行科学家进行调查。这项调查在了解巴塔哥尼亚的植物区系和气候变化方面取得了进展，促进了与巴塔哥尼亚和南极地区已知的其他化石组合的详细比较。新的化石地点，如多罗塔和圣塞巴斯蒂安部分，以及非凡的保存，如来自Riesco岛的过矿化植物碎片，将在未来进行广泛研究时提供进一步的有用数据。较少

Localities extending chronologically from the Late Cretaceous to the Oligocene were selected for fossil sampling to obtain informative materials for the project. Sampling was authorized by documents #4062, and #3708 issued by the Concejo de Monumentos Nacionales de Chile. In addition to previously targeted fossil-bearing sites, we found several new sites. Samples and micropreparations will be archived at the Museo Nacional de Historia Natural in Santiago, Chile. Supplementary duplicates are also deposited in the National Science Museum, Tokyo. The investigation members have continued to study materials collected in the three field researches that had been carried out in Chile during three fiscal years 2002-2004. In addition to the ordinary investigators, two scientists of Fukui Prefectural Dinosaur Museum, Kazuo Terada and Atsushi Yabe, joined the investigation as associate research members. Also a Chilean counterpart Luis Felipe Hinojosa was invited to Japan in June 2005 for material … More investigation and discussion. The results obtained until December 2005 were published as an joint issue including 9 papers, which is entitled "Post-Cretaceous Floristic Changes in Southern Patagonia, Chile" (Nishida H. ed., Chuo University, Tokyo, 107 pp.) at the end of 2005 fiscal year. Pollen analysis on bog-boring cores collected in Chile and Argentina is still in progress under management by Okuda. The core samples collected in Argentina are being investigated by Argentine counterpart scientists represented by Jorge Rabassa of CADIF-CONICET, Ushuaia. The results will be published elsewhere separately.This investigation made progress in understanding the floristic and climatic changes in Patagonia, promoting detailed comparisons with studies on other fossil assemblages known from Patagonia and the Antarctic regions. The new fossil localities, such as the Dorotea and San Sebastian sections, and the extraordinary preservation, such as permineralized plant debris from Riesco Island, will provide further useful data when studied extensively in the future.
